The Japanese counter suffix 「つ」 is commonly used to count everyday items such as apples, rice balls, and snacks. It can also be used to count questions, reasons, and options. 「一つ、二つ、三つ」 are pronounced 「ひとつ、ふたつ、みっつ」, respectively. However, when counting to ten, you say 「十（とお）」, not 「十つ」. This counting system also cannot be extended in the same way to eleven or higher.
When shopping in Japan, you can say 「おにぎりを二つください」 if you want to buy two rice balls. However, when counting tickets, books, or drinks, Japanese generally uses specific counters such as 「枚」「冊」 and 「杯」. So what is the difference between 「つ」 and 「個」? When can you simply use 「つ」? In addition to explaining how to pronounce the numbers from one to ten, this article introduces the uses of 「いくつ」「一つずつ」 and 「二つ目」, with everyday examples involving shopping and ordering food to show how these expressions are used in practice.
How to Use the Japanese Counter 「つ」: What Objects and Things Can It Count?
The Japanese counter 「つ」 is used to count ordinary objects, but it can also count abstract things such as questions, reasons, and options. Common expressions include 「一つ（ひとつ）」「二つ（ふたつ）」 and 「三つ（みっつ）」. In Chinese, these may be translated using different measure words depending on what is being counted, such as 「一個」「兩份」 or 「三項」.
「つ」 has a wide range of uses. Items such as apples, cookies, and rice balls can all be counted using the same system, even though they have different shapes. Japanese also uses expressions such as 「質問が一つ」 and 「理由が二つ」 to indicate the number of questions or reasons. However, 「つ」 cannot replace every counter. Paper is usually counted with 「枚」, pens with 「本」, and books with 「冊」. Each of these items has its own conventional counter.
For example, 「ケーキを一つください」 means that you would like one serving of cake. When ordering food in everyday situations, there is no need to distinguish the cake's shape. However, if you want two tickets, you would normally say 「切符を二枚ください」 rather than simply using 「二つ」. Therefore, when deciding whether to use 「つ」, consider what you are counting and whether Japanese has a more commonly used counter for that item.
- Example: 質問が一つあります。
Kana: しつもんがひとつあります。
Translation: I have one question.
Although 「質問」 is not a physical object, it can still be counted using 「一つ」. Here, the expression indicates that there is one question someone would like to ask. - Example: りんごを二つ買いました。
Kana: りんごをふたつかいました。
Translation: I bought two apples.
「二つ」 indicates the quantity purchased and appears before the verb 「買いました」. Apples can also be counted using 「個」, so 「りんごを二個買いました」 is equally correct. - Example: 理由は三つあります。
Kana: りゆうはみっつあります。
Translation: There are three reasons.
「理由」 is an abstract concept, and 「三つ」 indicates that there are three reasons in total. This expression is also commonly used when listing questions, conditions, or options.
Sentence Patterns and Position of the Japanese Counter 「つ」: Expressing and Asking About Quantities
The most common sentence pattern using the Japanese counter 「つ」 is "noun + particle + quantity + verb," as in 「りんごを二つ買う」 and 「りんごが三つある」. The quantity usually appears after the particle 「を」 or 「が」 and before the verb. There is no need to add another particle after 「二つ」 or 「三つ」. If you want the quantity to directly modify a noun, use "quantity + の + noun," as in 「二つのりんご」. You cannot write 「二つりんご」 without 「の」.
To ask about a quantity, you can replace a specific number such as 「一つ」 or 「二つ」 with 「いくつ」, creating the pattern "noun + は／が／を + いくつ + verb." You can also attach 「ずつ」 or 「目」 directly to quantity expressions using 「つ」, as in 「一つずつ」 and 「二つ目」. If a noun follows 「二つ目」, you need to add 「の」 to form 「二つ目の角」. The main differences between these patterns concern where the quantity expression appears and whether a particle is needed after it.
| Construction type | Pattern | Example | Note |
| Quantity before the verb | N＋が／を＋quantity＋V | りんごを二つ買う | Usually no additional particle after the quantity |
| Quantity directly modifying a noun | Quantity＋の＋N | 二つのりんご | 「の」 is required between the quantity and the noun |
| Asking about quantity | N＋は／が／を＋いくつ＋V | りんごはいくつありますか | Replace the specific quantity with 「いくつ」 |
| Distributing a quantity | Quantity＋ずつ＋V | 一つずつ取る | 「ずつ」 attaches directly after the quantity |
| Indicating order | Quantity＋目＋の＋N | 二つ目の角 | 「目」 attaches directly to the quantity; add 「の」 when modifying a noun |
Japanese 「つ」 Pattern ① | Add 「が／を」 After the Noun and Place the Quantity Before the Verb
When using 「つ」 to express a quantity, the most common word order is "noun + が／を + quantity + verb." For example, in 「りんごを二つ買いました」, the particle 「を」 first identifies what was purchased, and 「二つ」 appears before the verb 「買いました」. Here, 「二つ」 already expresses the quantity, so another 「を」 is unnecessary.
If you want to place the quantity directly before a noun, you can use "quantity + の + noun," as in 「二つの箱」. Both sentence patterns are grammatically correct, but when describing purchases or the number of objects in everyday Japanese, expressions such as 「箱を二つ運ぶ」 and 「りんごを二つ買う」, which place the quantity before the verb, are common.
- Example: りんごを二つ買いました。
Kana: りんごをふたつかいました。
Translation: I bought two apples.
This sentence follows the order 「りんご＋を＋二つ＋買いました」. The particle 「を」 follows the noun, while 「二つ」 appears directly before the verb without an additional particle. - Example: 質問が三つあります。
Kana: しつもんがみっつあります。
Translation: There are three questions.
The particle 「が」 follows 「質問」, followed by the quantity 「三つ」 and the existence verb 「あります」, forming the pattern "N + が + quantity + あります." - Example: 二つの箱を運びました。
Kana: ふたつのはこをはこびました。
Translation: I carried two boxes.
When the quantity appears directly before the noun 「箱」, the construction must be 「二つ＋の＋箱」. The particle 「の」 connects the quantity to the noun and cannot be omitted.
Japanese 「つ」 Pattern ② | Replace a Specific Number With 「いくつ」 to Ask About Quantity
「いくつ」 is the question word corresponding to 「一つ、二つ、三つ……」. It follows the same placement rules as ordinary quantity expressions and can appear before predicates such as 「あります」「買いました」 and 「必要です」. For example, changing 「りんごが二つあります」 to 「りんごはいくつありますか」 turns a statement about two apples into a question about how many apples there are.
If the object being counted has already been mentioned in the sentence, you can generally replace the quantity with 「いくつ」 without adding 「つ」 or another counter. Choose the particle after the noun according to the original sentence structure. For example, 「が」 marks something that exists, 「を」 marks the object of an action, and 「は」 introduces the topic being asked about.
- Example: みかんはいくつありますか。
Kana: みかんはいくつありますか。
Translation: How many mandarins are there?
This sentence uses the structure 「みかん＋は＋いくつ＋ありますか」. Simply replace the position normally occupied by 「一つ」 or 「二つ」 with 「いくつ」. - Example: お菓子をいくつ買いましたか。
Kana: おかしをいくつかいましたか。
Translation: How many snacks did you buy?
The particle 「を」 follows 「お菓子」, and 「いくつ」 appears before the verb 「買いました」, following the same word order as 「お菓子を三つ買いました」. - Example: チケットはいくつ必要ですか。
Kana: チケットはいくつひつようですか。
Translation: How many tickets do you need?
「いくつ」 appears before 「必要です」, forming the pattern "N + は + いくつ + 必要ですか." If you want to use the specific counter for tickets, you can also say 「チケットは何枚必要ですか」.
Japanese 「つ」 Pattern ③ | Attach 「ずつ」 and 「目」 Directly to Quantities, Adding 「の」 Before a Noun
「一つずつ」 and 「二つ目」 are expressions formed by adding another element to a quantity word. 「ずつ」 attaches directly to the complete quantity expression, creating the pattern "quantity + ずつ," as in 「一つずつ」 and 「二つずつ」. You can then add verbs such as 「取る」「配る」 or 「渡す」 to describe an action. No particle is needed between the quantity and 「ずつ」.
「目」 follows the pattern "quantity + 目," as in 「一つ目」「二つ目」 and 「三つ目」. To modify a following noun, add 「の」, forming expressions such as 「二つ目の信号」 and 「三つ目の質問」. Therefore, 「二つ目の角」 is a complete noun-modifying construction. You cannot omit 「の」 and write 「二つ目角」.
- Example: クッキーを一つずつ配りました。
Kana: クッキーをひとつずつくばりました。
Translation: I handed out the cookies one at a time.
This uses the construction 「一つ＋ずつ」. The element 「ずつ」 attaches directly to the quantity expression, followed by the verb 「配りました」, without an additional particle. - Example: 二つ目の角を右に曲がってください。
Kana: ふたつめのかどをみぎにまがってください。
Translation: Please turn right at the second corner.
「二つ＋目＋の＋角」 forms a noun-modifying construction. 「目」 attaches directly to 「二つ」, while 「の」 connects the expression to the following noun 「角」. - Example: 三つ目の質問に答えてください。
Kana: みっつめのしつもんにこたえてください。
Translation: Please answer the third question.
This follows the pattern 「三つ＋目＋の＋質問」. First, 「目」 is added to 「三つ」, then 「の」 connects it to the noun 「質問」, followed by the particle 「に」 and the verb 「答えてください」.
How to Use the Japanese Counter 「つ」: What Objects and Things Can It Count?
The Japanese counter 「つ」 can count ordinary objects as well as abstract things such as questions, reasons, and options. In addition to basic counting expressions such as 「一つ」「二つ」 and 「三つ」, everyday Japanese uses 「いくつ」 to ask about quantities, 「一つずつ」 to indicate distributing items one by one, and 「二つ目」 to indicate order.
The meaning depends on what you want to express. When shopping, 「二つ」 might refer to two products, while in a restaurant it might mean two servings of food. When discussing a topic, 「三つ」 can refer to three reasons or three conditions. The following six common uses are explained with example sentences to show how the meaning changes across situations.
Japanese Counter 「つ」 Usage ① | Counting Ordinary Objects
「つ」 is most commonly used to count ordinary objects such as apples, cookies, rice balls, and boxes. Although these items have different shapes and sizes, you can use 「一つ」「二つ」「三つ」 and similar expressions when counting individual items.
For example, 「りんごを二つ買いました」 means that you bought two apples, while 「箱が四つあります」 means that there are four boxes. However, when an item has a more conventional specific counter, such as 「枚」 for paper or 「冊」 for books, that counter is usually preferred.
- Example: りんごを二つ買いました。
Kana: りんごをふたつかいました。
Translation: I bought two apples.
Apples are ordinary objects that can be counted using 「つ」, so 「二つ」 directly indicates two apples. You can also replace it with 「二個」. - Example: 箱が四つあります。
Kana: はこがよっつあります。
Translation: There are four boxes.
「四つ」 indicates the number of boxes. Even if the boxes differ in size, this expression can be used as long as you are counting individual boxes. - Example: みかんを六つ買いました。
Kana: みかんをむっつかいました。
Translation: I bought six mandarins.
Fruits can often be counted using 「つ」. 「六つ」 is pronounced 「むっつ」, and the small 「っ」 indicates a pause in pronunciation known as a geminate consonant. It cannot be pronounced 「ろくつ」.
Japanese Counter 「つ」 Usage ② | Counting Abstract Things Such as Questions, Reasons, and Options
「つ」 can also count things that cannot be seen or touched, such as questions, reasons, conditions, methods, and options. For example, 「質問が一つあります」 means that there is one question, while 「理由は三つあります」 means that there are three reasons. The items being counted do not have to be physical objects.
This usage frequently appears in discussions, meetings, and explanations. In particular, when listing several points, 「一つ」「二つ」 and 「三つ」 can indicate the total number of items without requiring a different counter.
- Example: 質問が一つあります。
Kana: しつもんがひとつあります。
Translation: I have one question.
Although 「質問」 is an abstract concept, it can still be counted with 「一つ」. You can use this sentence to indicate that you would like to ask a question during a meeting, class, or discussion. - Example: 理由は三つあります。
Kana: りゆうはみっつあります。
Translation: There are three reasons.
「三つ」 indicates that there are three reasons in total. This is common when explaining a decision, analyzing causes, or preparing to list reasons. - Example: 確認したいことが二つあります。
Kana: かくにんしたいことがふたつあります。
Translation: There are two things I would like to confirm.
「確認したいこと」 refers to matters someone wants to confirm, and 「二つ」 indicates that there are two of them. Here, the expression counts matters rather than physical objects.
Japanese Counter 「つ」 Usage ③ | Expressing Quantities of Products or Servings When Shopping and Ordering Food
At convenience stores, bakeries, and restaurants, 「つ」 is often used to indicate how many products you want to purchase or how many servings you want to order. For example, 「ケーキを二つお願いします」 means that you would like two servings of cake, while 「カレーを一つください」 means that you would like one serving of curry.
In these situations, 「つ」 counts products or servings listed on the menu, not necessarily the containers holding them. Therefore, even if the curry is served on a plate, you do not need to use a counter for plates. However, if you want to specify the number of cups of a drink, using 「杯」 is more precise, as in 「コーヒーを二杯ください」.
- Example: このおにぎりを三つください。
Kana: このおにぎりをみっつください。
Translation: Please give me three of these rice balls.
When shopping at a convenience store, you can use 「三つ」 directly to indicate that you want three rice balls, without using a specialized counter. - Example: ケーキを二つお願いします。
Kana: ケーキをふたつおねがいします。
Translation: Two servings of cake, please.
Here, 「二つ」 indicates two servings. This is a natural way to order from a staff member, and you do not need to specify the shape of the cake. - Example: カレーを一つください。
Kana: カレーをひとつください。
Translation: One serving of curry, please.
「一つ」 indicates one serving of curry on the menu rather than counting the plate itself. In restaurants, an entire dish is often treated as one counting unit.
Japanese Counter 「つ」 Usage ④ | Using 「いくつ」 to Ask About the Number of Objects or Things
When you do not know how many items there are, you can use 「いくつ」 to ask about the quantity. For example, 「みかんはいくつありますか」 asks how many mandarins there are, while 「質問はいくつありますか」 asks how many questions there are.
「いくつ」 generally corresponds to the 「一つ」「二つ」「三つ」 counting system and is suitable for asking about the number of ordinary objects or abstract things. However, if an item has a conventional specific counter, you can also use expressions such as 「何枚」「何本」 or 「何冊」. For example, when asking how many tickets there are, 「何枚」 is generally more specific than 「いくつ」.
- Example: みかんはいくつありますか。
Kana: みかんはいくつありますか。
Translation: How many mandarins are there?
「いくつ」 asks about the number of mandarins. You can answer 「三つあります」 to indicate that there are three. - Example: お菓子をいくつ買いましたか。
Kana: おかしをいくつかいましたか。
Translation: How many snacks did you buy?
「いくつ」 asks about the quantity purchased without specifying the type of snack. Depending on the actual quantity, you can answer using expressions such as 「二つ」 or 「四つ」. - Example: 質問はいくつありますか。
Kana: しつもんはいくつありますか。
Translation: How many questions are there?
「いくつ」 can also ask about the number of abstract things. Here, the question concerns the total number of questions rather than the number of physical objects.
Japanese Counter 「つ」 Usage ⑤ | Using 「一つずつ」 to Process or Distribute Items One by One
「一つずつ」 means one per person, one at a time, or handling things individually in sequence. 「ずつ」 conveys the idea of equal distribution or proceeding step by step, so it is commonly used when handing out items, assigning tasks, or working through problems.
For example, 「一人一つずつ取ってください」 means that each person should take one, while 「問題を一つずつ解きましょう」 means working through problems one at a time. If two items are distributed to each person or handled at each step, you can use 「二つずつ」. The pattern is not limited to 「一つずつ」.
- Example: 一人一つずつ取ってください。
Kana: ひとりひとつずつとってください。
Translation: Please take one each.
「一つずつ」 expresses equal distribution, meaning that each person takes one. It is commonly used when handing out snacks, souvenirs, or supplies at an event. - Example: 問題を一つずつ解きましょう。
Kana: もんだいをひとつずつときましょう。
Translation: Let's solve the problems one at a time.
Here, 「一つずつ」 indicates working through something in sequence, completing one problem before moving on to the next. It does not refer to distributing physical objects. - Example: お皿にクッキーを二つずつ置いてください。
Kana: おさらにクッキーをふたつずつおいてください。
Translation: Please put two cookies on each plate.
「二つずつ」 indicates that two cookies should be placed on each plate. Compared with 「一つずつ」, the number distributed changes from one to two, but the meaning of equal distribution remains the same.
Japanese Counter 「つ」 Usage ⑥ | Using 「二つ目」 and 「三つ目」 to Indicate Order
「一つ目」「二つ目」 and 「三つ目」 indicate positions in a sequence, corresponding to "first," "second," and "third." For example, 「二つ目の角」 means the second corner, while 「三つ目の質問」 means the third question.
These expressions are common when giving directions, listing options, or discussing a topic. Pay attention to the difference between 「二つ」 and 「二つ目」: the former indicates that there are two items in total, while the latter identifies the second item in a sequence. Therefore, 「質問が二つあります」 and 「二つ目の質問」 describe different things.
- Example: 二つ目の信号を右に曲がってください。
Kana: ふたつめのしんごうをみぎにまがってください。
Translation: Please turn right at the second traffic light.
「二つ目」 identifies the second traffic light encountered in the direction of travel. The focus is on its position in the sequence, not the total number of traffic lights. - Example: 三つ目の質問に答えてください。
Kana: みっつめのしつもんにこたえてください。
Translation: Please answer the third question.
「三つ目」 identifies the third question in a sequence. You can use this expression even if there are more than three questions in total. - Example: 一つ目の案を採用しました。
Kana: ひとつめのあんをさいようしました。
Translation: We adopted the first proposal.
「一つ目」 identifies the proposal that appears first in the sequence. When discussing several proposals or options, you can use 「一つ目」 and 「二つ目」 to refer to specific items.
The Difference Between Japanese 「つ」 and 「個」: When to Use 「枚」「本」「冊」 or 「杯」
The Japanese counter 「つ」 can count many ordinary objects as well as abstract things such as questions and reasons. In contrast, 「個」 is commonly used to count individual objects, such as apples, eggs, and erasers. Their uses overlap considerably. For example, both 「りんごを二つ」 and 「りんごを二個」 can mean two apples.
However, Japanese uses different counters depending on an object's shape, type, or how it is counted. Paper is usually counted with 「枚」, pens with 「本」, books with 「冊」, cups of drinks with 「杯」, and people with 「人」. These counters have their own counting categories and cannot all be replaced directly with 「つ」. In addition, 「つ」 uses the native Japanese counting system from one to ten, so quantities of eleven or more require a different counting system or counter.
| Comparison | 「つ」 | 「個（こ）」 | 「枚（まい）」 | 「本（ほん）」 | 「冊（さつ）」 | 「杯（はい）」 | 「人（にん）」 |
| Basic meaning | Items, servings, or points | Individual items | Sheets or flat pieces | Long, thin items or bottles | Volumes or books | Cups or glasses | People |
| Main counting targets | Ordinary objects and abstract things | Individual or small objects | Paper, tickets, and other thin objects | Pens, umbrellas, bottles, and other long objects | Books, notebooks, and magazines | Drinks served in cups or glasses | People |
| What is counted | The quantity itself | Separate individual units | Number of flat items | Number of long or cylindrical items | Number of books or volumes | Number of cups or glasses | Number of people |
| Common situations | Shopping, ordering food, listing points | Shopping, counting inventory | Buying tickets, distributing paper | Buying pens, counting bottles | Buying and organizing books | Ordering drinks | Reservations, counting people |
| How to say two | 二つ（ふたつ） | 二個（にこ） | 二枚（にまい） | 二本（にほん） | 二冊（にさつ） | 二杯（にはい） | 二人（ふたり） |
| Can it count abstract things? | Yes, with a wide range of uses | Also possible in conversational Japanese | Generally not applicable | Generally not applicable | Generally not applicable | Generally not applicable | Cannot directly count abstract things |
| Can it be interchanged with 「つ」? | — | Yes, for some objects | Sometimes, but the counting focus differs | Sometimes, but the counting focus differs | 「冊」 is usually preferred | Sometimes when ordering, but the counting focus differs | Cannot be directly interchanged |
| Eleven or more | Cannot continue adding 「つ」 | Yes | Yes | Yes | Yes | Yes | Yes |
| Example | りんごを二つ買う。 | 卵を三個買う。 | 切符を二枚買う。 | ペンを三本買う。 | 本を二冊買う。 | コーヒーを二杯頼む。 | 学生が三人いる。 |
▌「つ」 vs. 「個」 | General Quantities vs. Individual Objects
「つ」 and 「個」 overlap in many situations, particularly when counting objects such as apples, eggs, and snacks. Both 「りんごを二つ買いました」 and 「りんごを二個買いました」 mean that you bought two apples, with no noticeable difference in politeness.
The main difference lies in the range of things they can count. In addition to physical objects, 「つ」 is frequently used for abstract things such as questions, reasons, and conditions. 「個」 is more commonly used for separate individual objects. However, you may also hear 「質問が二個ある」 in everyday speech, so it would be inaccurate to say that 「個」 can never count abstract things.
Another difference is the range of numbers. The native Japanese counting system using 「つ」 only goes up to ten. Beyond ten, you cannot continue adding 「つ」. In contrast, 「個」 can be used with numbers such as eleven and twelve.
- Example: りんごを二つ買いました。
Kana: りんごをふたつかいました。
Translation: I bought two apples.
「二つ」 indicates the number purchased. You can also use 「二個」 here. Both sentences sound natural, and their meanings are essentially the same. - Example: 卵を三個買いました。
Kana: たまごをさんこかいました。
Translation: I bought three eggs.
「三個」 counts the eggs as separate individual objects. You can also say 「卵を三つ買いました」 because eggs can be counted using 「つ」 as well. - Example: 理由は三つあります。
Kana: りゆうはみっつあります。
Translation: There are three reasons.
「理由」 is an abstract concept, and using 「三つ」 is natural. You may also hear 「理由が三個ある」 in conversation, but 「三つ」 is generally more appropriate in explanations and written articles.
▌「つ」 vs. 「枚」 | General Quantities vs. Flat Objects
「つ」 is used to count ordinary objects, while 「枚」 is mainly used for flat, thin items such as paper, tickets, photographs, and postcards. When you need to specify the number of sheets of paper or tickets, using 「枚」 sounds more natural than 「つ」.
For example, 「切符を二枚ください」 means that you want two tickets. If you change this to 「切符を二つください」, the listener might still understand that you want two items in certain shopping situations. However, Japanese normally uses 「枚」 to count tickets.
The two counters may also produce different meanings when the counting units differ. For example, if paper is sold in packs, 「一つ」 might refer to one pack of paper, while 「一枚」 refers to a single sheet inside it.
- Example: 紙を三枚ください。
Kana: かみをさんまいください。
Translation: Please give me three sheets of paper.
Paper is a thin, flat object, so 「三枚」 clearly specifies three sheets. Saying only 「三つ」 does not directly indicate the number of sheets. - Example: 切符を二枚買いました。
Kana: きっぷをにまいかいました。
Translation: I bought two tickets.
Tickets are usually counted using 「枚」, so 「二枚」 is the natural expression. When buying tickets, 「枚」 is more appropriate than 「つ」 if you want to specify how many tickets you need.
▌「つ」 vs. 「本」 | General Quantities vs. Long, Thin Objects
「つ」 can express the number of objects in general, while 「本」 is commonly used to count long, thin objects such as pencils, ballpoint pens, umbrellas, and bottled drinks. Japanese chooses counters according to the characteristics of the object, so when counting pens, you would normally say 「ペンを二本」 rather than 「ペンを二つ」.
「本」 also changes pronunciation depending on the number, taking the forms 「ほん」「ぼん」 and 「ぽん」. For example, 「一本（いっぽん）」「二本（にほん）」 and 「三本（さんぼん）」. In contrast, 「つ」 uses native Japanese counting expressions such as 「ひとつ、ふたつ、みっつ」. You cannot mix the pronunciations of these two systems.
Furthermore, 「本」 is not limited to pens or stick-shaped objects. It is also commonly used for bottled drinks. For example, 「水を二本買いました」 generally means that you bought two bottles of water, rather than simply two servings of water.
- Example: ペンが二本あります。
Kana: ペンがにほんあります。
Translation: There are two pens.
Pens are long, thin objects, so 「二本」 is the most natural expression. Although 「二つ」 may sometimes indicate two products in shopping situations, 「本」 is generally used when clearly counting individual pens. - Example: 水を三本買いました。
Kana: みずをさんぼんかいました。
Translation: I bought three bottles of water.
Here, 「三本」 generally refers to three bottles of water, counting the bottles themselves. 「本」 is pronounced 「ぼん」 in this expression, not 「さんほん」.
▌「つ」 vs. 「冊」 | General Quantities vs. Books and Bound Volumes
「冊」 is mainly used to count bound items such as books, notebooks, dictionaries, and magazines. Although 「つ」 can count a broad range of objects, Japanese normally uses 「冊」 when counting books.
For example, 「本を二冊買いました」 means that you bought two books. Using 「二冊」 makes it clear that you are counting individual volumes. Although 「本を二つ買いました」 might be understood as two products in certain situations, it is not the most conventional way to count books.
Also, because Chinese uses the measure word 「本」 to count books, it is important not to confuse the Japanese counters 「冊」 and 「本」. In Japanese, 「本（ほん）」 is a counter for long, thin objects, while 「冊（さつ）」 is the counter used for books.
- Example: 本を二冊買いました。
Kana: ほんをにさつかいました。
Translation: I bought two books.
「二冊」 indicates two books and follows the conventional Japanese counting system for books. The fact that Chinese uses 「兩本書」 does not mean that the Japanese counter 「本」 should be used. - Example: ノートを三冊使いました。
Kana: ノートをさんさつつかいました。
Translation: I used three notebooks.
Notebooks are also bound items, so 「三冊」 is used. If you want to specify the number of notebooks, 「三つ」 would not normally be the preferred counter.
▌「つ」 vs. 「杯」 | Servings of Food vs. Cups of Drinks
Both 「つ」 and 「杯」 are frequently used when ordering at restaurants and cafés, but they focus on different counting units. 「つ」 can count a dish or drink as one item on the menu, while 「杯」 is used to count drinks served in cups or glasses.
For example, saying 「コーヒーを二つください」 at a café will generally be understood as ordering two coffees. Saying 「コーヒーを二杯ください」 explicitly indicates that you want two cups of coffee.
Therefore, in some ordering situations, both expressions may refer to the same quantity, but their nuances are not identical. The former focuses on the number of products ordered, while the latter directly specifies the conventional counting unit for drinks. 「杯」 also changes pronunciation depending on the number, as in 「一杯（いっぱい）」「二杯（にはい）」 and 「三杯（さんばい）」.
- Example: コーヒーを二つください。
Kana: コーヒーをふたつください。
Translation: Two coffees, please.
「二つ」 counts coffee as an item on the menu. It can be used when ordering two coffees at a café. - Example: コーヒーを二杯ください。
Kana: コーヒーをにはいください。
Translation: Two cups of coffee, please.
「二杯」 explicitly indicates two cups of coffee, making the counting unit clearer than 「二つ」. - Example: ケーキを一つ、紅茶を一杯お願いします。
Kana: ケーキをひとつ、こうちゃをいっぱいおねがいします。
Translation: One serving of cake and one cup of black tea, please.
Different counters can be used in the same order. The cake is counted as one item using 「一つ」, while the tea is counted by the cup using 「一杯」.
▌「つ」 vs. 「人」 | Numbers of Objects vs. Numbers of People
「つ」 is mainly used to count objects and things, and it cannot directly be used to count people. When counting people in Japanese, you must use 「人」, as in 「一人（ひとり）」「二人（ふたり）」 and 「三人（さんにん）」.
This distinction frequently arises when making restaurant reservations, checking into hotels, or buying tickets. For example, 「二人です」 means that there are two people, while 「二つください」 means that you want two items. These expressions cannot be used interchangeably.
It is also important to note that 「人」 has special pronunciation patterns. One person is 「一人（ひとり）」, and two people is 「二人（ふたり）」. From three people onward, Japanese generally uses Sino-Japanese numbers with 「人」, as in 「三人（さんにん）」.
- Example: 学生が三人います。
Kana: がくせいがさんにんいます。
Translation: There are three students.
「三人」 indicates three people. Because the subjects being counted are students, you must use the counter for people. You cannot replace it with 「学生が三ついます」. - Example: 二人分のチケットをください。
Kana: ふたりぶんのチケットをください。
Translation: Please give me tickets for two people.
「二人分」 indicates the amount or allocation required for two people, emphasizing the number of people. If you simply want two tickets, you can also say 「チケットを二枚ください」. - Example: 椅子が二つあります。
Kana: いすがふたつあります。
Translation: There are two chairs.
「二つ」 counts the chairs. If you change this to 「二人います」, you would be counting two people instead. Just because two chairs can seat two people does not mean that 「つ」 and 「人」 can be used interchangeably.
▌How Different Counters Change the Nuance in the Same Situation
Imagine ordering two servings of cake and two cups of coffee at a café in Japan. Even when the quantity is the same—two—the nuances change depending on whether you use 「つ」「個」 or 「杯」.
「つ」 can count cake or coffee as items on the menu. 「個」 places more emphasis on treating each cake as a separate individual object, while 「杯」 explicitly indicates the number of cups of coffee. Even when you receive the same quantity of products, the unit of measurement being emphasized is different.
- Example: ケーキを二つお願いします。
Kana: ケーキをふたつおねがいします。
Translation: Two servings of cake, please.
「二つ」 treats the cakes as two items on the menu and is a very natural expression when ordering at a café. There is no need to specify their shape or size. - Example: ケーキを二個お願いします。
Kana: ケーキをにこおねがいします。
Translation: Two individual cakes, please.
「二個」 counts the cakes as two separate products. This expression can also be used when buying cakes sold individually, although 「二つ」 is generally more natural when ordering at a café. - Example: コーヒーを二つお願いします。
Kana: コーヒーをふたつおねがいします。
Translation: Two coffees, please.
「二つ」 counts coffee as two items on the menu. As long as the ordering context is clear, the staff will generally understand that you want two coffees, even without the counter 「杯」. - Example: コーヒーを二杯お願いします。
Kana: コーヒーをにはいおねがいします。
Translation: Two cups of coffee, please.
「二杯」 directly indicates the number of cups of coffee. Compared with 「二つ」, this expression uses the conventional counter for drinks and specifies the counting unit more clearly.
All of these expressions may appear in the same ordering situation. Both 「ケーキを二つ」 and 「ケーキを二個」 refer to two servings of cake, but the former counts them as general menu items, while the latter emphasizes the number of separate individual objects. Similarly, 「コーヒーを二つ」 and 「コーヒーを二杯」 can both indicate two coffees, but the latter explicitly specifies the number of cups.
If the items being counted are tickets, pens, or books instead, you would normally use 「枚」「本」 and 「冊」, respectively. Therefore, Japanese counters are not simply different Japanese equivalents of the Chinese measure word 「個」. You need to choose a counter according to the type of object and the specific unit being counted in the situation.
How to Use 「つ」 When Traveling in Japan: Convenience Store Shopping, Restaurant Orders, and Sharing Snacks
The Japanese counter 「つ」 is frequently used when shopping, ordering food, or checking quantities while traveling in Japan. For example, you can use expressions such as 「一つ」「二つ」 and 「三つ」 when buying three rice balls at a convenience store, ordering two servings of cake at a café, or sharing snacks with travel companions. When you need to ask about the quantity, you can use 「いくつ」.
However, although 「つ」 is convenient, it does not mean that every item should be counted in the same way. You can say 「ケーキを二つお願いします」 at a restaurant, but when specifically ordering two cups of coffee, you would normally say 「コーヒーを二杯お願いします」. Also, customers generally pick up products themselves at Japanese convenience stores, so 「つ」 often appears when friends traveling together discuss how many items to buy. The following three travel situations show how these expressions are used in actual conversations.
▌Situation ① | Buying Three Rice Balls at a Convenience Store Using 「三つ」
A：このおにぎり、いくつ買う？
このおにぎり、いくつかう？
How many of these rice balls should we buy?
B：三つ買おう。三人で一つずつ食べよう。
みっつかおう。さんにんでひとつずつたべよう。
Let's buy three. There are three of us, so we can each have one.
📌 Grammar Point: 「いくつ買う？」 asks how many items to buy. To answer, simply say 「三つ買おう」, placing 「三つ」 before the verb 「買う」. The following expression, 「一つずつ」, indicates that one item will be distributed to each person, which differs from simply saying 「三つ」. Pay attention to the small 「っ」 in 「三つ（みっつ）」, which represents a pause in pronunciation. It should not be pronounced 「みつ」. In Japanese convenience stores, customers usually select products directly from the shelves, so this conversation between friends discussing how many items to buy is more typical of an ordinary shopping situation than telling the cashier 「三つください」.
▌Situation ② | Ordering Two Servings of Cake at a Café Using 「二つ」
A：このケーキを二つお願いします。
このケーキをふたつおねがいします。
Two servings of this cake, please.
B：かしこまりました。お飲み物はいかがなさいますか。
かしこまりました。おのみものはいかがなさいますか。
Certainly. Would you like anything to drink?
📌 Grammar Point: 「ケーキを二つお願いします」 follows the pattern "noun + を + quantity + お願いします". 「二つ」 indicates two servings of cake, without requiring any distinction based on the cake's shape or container. You can also use 「二個」 when buying cakes sold as individual items, but 「二つ」 is very natural when ordering at a typical café. Here, 「お願いします」 is a polite way to place an order with a staff member. If you also want two cups of coffee, you can continue with 「コーヒーを二杯お願いします」, using 「杯」 to specify the number of cups.
▌Situation ③ | Using 「いくつ」 and 「一つずつ」 to Check and Share the Remaining Snacks
A：お菓子、あといくつある？
おかし、あといくつある？
How many snacks are left?
B：四つあるよ。四人だから、一人一つずつね。
よっつあるよ。よにんだから、ひとりひとつずつね。
There are four left. There are exactly four of us, so that's one each.
📌 Grammar Point: 「あといくつある？」 asks about the remaining quantity, with 「あと」 conveying the meaning of "still left" or "remaining." 「四つあるよ」 answers the quantity directly using 「四つ」, which is pronounced 「よっつ」, not 「よんつ」. The following expression, 「一人一つずつ」, indicates that each person receives one item. Here, 「一人（ひとり）」 counts people, while 「一つ（ひとつ）」 counts snacks. These two counters can appear in the same sentence to indicate the number of people and the quantity of objects separately. They cannot all be replaced with 「つ」 simply because both involve counting.
Additional Usage Notes:
- When shopping or ordering food in Japan, 「つ」 is commonly used to indicate the quantity of products or servings. Expressions such as 「おにぎりを三つ」 and 「ケーキを二つ」 are natural because they describe how many items or servings are being purchased. However, tickets, notebooks, and cups of drinks are usually counted with counters such as 「枚」「冊」 and 「杯」, depending on the item. For example, 「チケットを二枚ください」 means that you want two tickets, while 「コーヒーを二杯ください」 means that you want two cups of coffee. These are common quantity expressions when traveling.
- In addition to asking how many items to buy, 「いくつ」 can be used to check how many items are available or remaining. For example, 「いくつありますか」 means "How many are there?" while 「あといくつありますか」 means "How many are left?" Among friends, you can use more casual expressions such as 「いくつある？」 and 「いくつ買う？」. When asking a staff member, you can use a polite form such as 「いくつありますか」. However, if you are asking how many tickets there are or how many cups of a drink are needed, 「何枚」 and 「何杯」 generally follow Japanese counting conventions more closely.
- When traveling, pay attention to both the pronunciation and the limits of 「つ」. 「一つ（ひとつ）」「二つ（ふたつ）」 and 「三つ（みっつ）」 cannot simply be pronounced using the Sino-Japanese number readings 「いち、に、さん」. In particular, 「三つ（みっつ）」 and 「六つ（むっつ）」 sound similar, making them easy to confuse when a staff member confirms a quantity. In addition, this native Japanese counting system ends at 「十（とお）」. You cannot continue adding 「つ」 for numbers of eleven or higher. For example, if you want to buy eleven apples, you can say 「りんごを十一個ください」 rather than 「十一つ」.
How Does Japanese 「つ」 Compare With Korean 「개」?
Both the Japanese counter 「つ」 and the Korean counter 「개」 can be used to count everyday objects such as apples, bread, and cookies. Japanese uses the native counting system 「一つ（ひとつ）」「二つ（ふたつ）」「三つ（みっつ）」, while Korean places native Korean numbers before the counter 「개」 to form 「한 개」「두 개」 and 「세 개」. Both systems can express one, two, and three items, but the way numbers and counters are combined is different.
In addition to counting objects, Japanese 「つ」 can count abstract things such as questions and reasons. It also appears in expressions such as 「いくつ」「一つずつ」 and 「二つ目」. In these situations, Korean uses not only 「개」 but also expressions such as 「하나」「가지」「몇 개」「씩」 and 「번째」. Therefore, when comparing Japanese and Korean, it is helpful to understand the intended quantity first, then choose the appropriate Korean expression for the situation.
◆ Similar Expression ①: 「한 개／두 개／세 개」 for Counting Ordinary Objects
The Korean counter 「개」 is commonly used to count many everyday objects. Unlike Japanese 「つ」, Korean requires a native Korean number before the counter. For example, 「한 개」 means one item, 「두 개」 means two, and 「세 개」 means three. Here, 「한、두、세、네」 are the forms that 「하나、둘、셋、넷」 take before a counter. You cannot simply say 「하나 개」「둘 개」 or 「셋 개」.
Japanese 「つ」 is used only up to 「十（とお）」, and you cannot continue adding 「つ」 for eleven or higher. Korean 「개」 does not have this restriction and can continue to be used in expressions such as 「열 개」 and 「열한 개」. The two languages are quite similar when comparing basic quantities from one to ten, but beyond ten, Japanese needs to use counters such as 「個」 according to the object being counted.
- Example: 사과 두 개 주세요.
Romanization: sa-gwa du gae ju-se-yo.
Translation: Please give me two apples.
Japanese: りんごを二つください。
Kana: りんごをふたつください。
Korean uses 「두 개」 to count two apples, while Japanese uses 「二つ」. Both sentences can be used when buying fruit. The main difference is how the number and counter are combined. - Example: 빵 세 개 샀어요.
Romanization: ppang se gae sa-sseo-yo.
Translation: I bought three pieces of bread.
Japanese: パンを三つ買いました。
Kana: パンをみっつかいました。
Korean 「세 개」 and Japanese 「三つ」 both indicate three items. Korean places 「세 개」 before the verb, while Japanese uses 「三つ」. The position of the quantity is similar in both languages. - Example: 귤 네 개 있어요.
Romanization: gyul ne gae i-sseo-yo.
Translation: There are four mandarins.
Japanese: みかんが四つあります。
Kana: みかんがよっつあります。
Korean uses 「네 개」, while Japanese uses 「四つ」. Japanese 「四つ」 is pronounced 「よっつ」, while Korean combines the native number 「네」 with the counter 「개」. Neither language can simply apply the ordinary Sino-derived number readings in these expressions.
◆ Similar Expression ②: 「하나／가지／개」 for Counting Questions, Reasons, and Abstract Things
Japanese 「つ」 can count abstract things, as in 「質問が一つあります」 and 「理由が三つあります」. Korean can express the same meanings, but it does not necessarily use 「개」 in every case. For example, "I have one question" is commonly expressed as 「질문이 하나 있어요」, while "There are three reasons" can be expressed as 「이유가 세 가지 있어요」.
Korean 「하나」 is the native number for one and can independently indicate a single item. 「가지」 is often used to count methods, reasons, and types, with a nuance of distinguishing different items or categories. 「개」 can also count certain abstract things, as in 「문제가 두 개 있어요」. Therefore, situations that can be expressed using 「つ」 alone in Japanese may require different forms in Korean depending on the noun and conventional usage.
- Example: 질문이 하나 있어요.
Romanization: jil-mu-ni ha-na i-sseo-yo.
Translation: I have one question.
Japanese: 質問が一つあります。
Kana: しつもんがひとつあります。
Japanese uses 「一つ」 to count the question, while Korean uses 「하나」 directly. 「질문이 하나 있어요」 sounds natural when introducing a question, and it is not always necessary to add 「개」. - Example: 이유가 세 가지 있어요.
Romanization: i-yu-ga se ga-ji i-sseo-yo.
Translation: There are three reasons.
Japanese: 理由は三つあります。
Kana: りゆうはみっつあります。
Korean 「세 가지」 indicates three reasons, with a sense of dividing the reasons into three distinct points. Japanese simply uses 「三つ」 without needing another counter equivalent to 「가지」. - Example: 문제가 두 개 있어요.
Romanization: mun-je-ga du gae i-sseo-yo.
Translation: There are two problems.
Japanese: 問題が二つあります。
Kana: もんだいがふたつあります。
The Korean noun 「문제」 can be counted using 「개」, especially when counting individual problems or questions in an exercise. Both 「두 개」 and Japanese 「二つ」 can indicate two problems, but Korean does not always use 「개」 for every abstract concept.
◆ Similar Expression ③: 「몇 개」 Corresponds to Japanese 「いくつ」 When Asking About Quantity
Japanese 「いくつ」 is used to ask about the number of ordinary objects or abstract things, while Korean commonly uses 「몇 개」. For example, 「りんごはいくつありますか」 corresponds to 「사과가 몇 개 있어요?」. Both sentences ask how many apples there are.
Japanese 「いくつ」 is already a complete question word for quantity, so there is no need to add 「つ」 after it. In Korean, 「몇」 means "how many," and it generally needs to be combined with a counter such as 「개」 to ask clearly about the number of ordinary objects. If the object being counted changes to books, drinks, or people, Korean also uses 「몇 권」「몇 잔」 and 「몇 명」, similar to the Japanese expressions 「何冊」「何杯」 and 「何人」.
- Example: 사과가 몇 개 있어요?
Romanization: sa-gwa-ga myeot kkae i-sseo-yo?
Translation: How many apples are there?
Japanese: りんごはいくつありますか。
Kana: りんごはいくつありますか。
Both Korean 「몇 개」 and Japanese 「いくつ」 ask about an unknown quantity. Korean requires the counter 「개」, while Japanese uses 「いくつ」 directly. - Example: 빵을 몇 개 샀어요?
Romanization: ppang-eul myeot kkae sa-sseo-yo?
Translation: How many pieces of bread did you buy?
Japanese: パンをいくつ買いましたか。
Kana: パンをいくつかいましたか。
Both sentences place the expression asking about quantity before the verb. Japanese uses 「いくつ買いましたか」, while Korean uses 「몇 개 샀어요?」. Their basic functions are the same. - Example: 쿠키가 몇 개 필요해요?
Romanization: ku-ki-ga myeot kkae pi-ryo-hae-yo?
Translation: How many cookies do you need?
Japanese: クッキーはいくつ必要ですか。
Kana: クッキーはいくつひつようですか。
This example asks about the required quantity rather than how many items are currently available. Both Korean 「몇 개 필요해요?」 and Japanese 「いくつ必要ですか」 can be used to confirm how many items are needed when preparing supplies.
◆ Similar Expression ④: 「한 개씩／하나씩」 Corresponds to Japanese 「一つずつ」 for Distribution
Japanese 「一つずつ」 can mean one per person, one at a time, or handling things individually in sequence. Korean has similar expressions, usually using the pattern "quantity + 씩." For example, 「한 개씩」 means one item per person or at a time, while 「두 개씩」 means two items per person or at a time.
Korean can also use 「하나씩」 directly, without necessarily adding the counter 「개」. For example, 「문제를 하나씩 풀어요」 means solving problems one by one, which is very similar to Japanese 「問題を一つずつ解きます」. Both languages add an element after the quantity to indicate distribution or proceeding one item at a time. Japanese uses 「ずつ」, while Korean uses 「씩」.
- Example: 한 사람당 한 개씩 가져가세요.
Romanization: han sa-ram-dang han gae-ssik ga-jyeo-ga-se-yo.
Translation: Please take one each.
Japanese: 一人一つずつ取ってください。
Kana: ひとりひとつずつとってください。
Korean 「한 사람당」 means "per person," while 「한 개씩」 means one item each. Japanese uses 「一人一つずつ」. Both expressions describe distributing objects equally among people. - Example: 과자를 두 개씩 나눠 주세요.
Romanization: gwa-ja-reul du gae-ssik na-nwo ju-se-yo.
Translation: Please divide the snacks into portions of two.
Japanese: お菓子を二つずつ配ってください。
Kana: おかしをふたつずつくばってください。
Both Korean 「두 개씩」 and Japanese 「二つずつ」 indicate distributing items in groups of two. When handing out snacks, both sentences can mean giving two snacks to each person. - Example: 문제를 하나씩 풀어요.
Romanization: mun-je-reul ha-na-ssik pu-reo-yo.
Translation: Solve the problems one at a time.
Japanese: 問題を一つずつ解きます。
Kana: もんだいをひとつずつときます。
Korean uses 「하나씩」 here without adding 「개」. Since the focus is on working through the problems in order rather than emphasizing the counting unit for each individual problem, 「하나씩」 alone sounds natural. Japanese, meanwhile, continues to use 「一つずつ」.
◆ Similar Expression ⑤: 「첫 번째／두 번째／세 번째」 Corresponds to Japanese 「一つ目／二つ目／三つ目」 for Order
Japanese 「一つ目」「二つ目」 and 「三つ目」 indicate the first, second, and third items in a sequence. Korean commonly uses 「첫 번째」「두 번째」 and 「세 번째」 to describe the positions of objects, questions, or places in an ordered sequence.
The difference lies in how these expressions are formed. Japanese adds 「目」 after 「一つ、二つ、三つ」, while Korean uses 「번째」 to indicate order. Also, Korean normally uses 「첫 번째」 for the first item rather than simply adding 「번째」 after 「한 개」. Therefore, Japanese 「一つ目」 cannot be translated word for word into Korean as 「한 개 번째」.
- Example: 첫 번째 상자를 여세요.
Romanization: cheot beon-jjae sang-ja-reul yeo-se-yo.
Translation: Please open the first box.
Japanese: 一つ目の箱を開けてください。
Kana: ひとつめのはこをあけてください。
Korean 「첫 번째」 indicates the first box in a sequence, while Japanese uses 「一つ目」. Both sentences specify the first item in order, rather than indicating that only one box exists. - Example: 두 번째 신호등에서 오른쪽으로 도세요.
Romanization: du beon-jjae sin-ho-deung-e-seo o-reun-jjo-geu-ro do-se-yo.
Translation: Please turn right at the second traffic light.
Japanese: 二つ目の信号を右に曲がってください。
Kana: ふたつめのしんごうをみぎにまがってください。
Both Korean 「두 번째」 and Japanese 「二つ目」 refer to the second traffic light encountered in the direction of travel. This is a common expression when giving directions, where the order of the traffic lights is what matters. - Example: 세 번째 질문이에요.
Romanization: se beon-jjae jil-mu-ni-e-yo.
Translation: This is the third question.
Japanese: 三つ目の質問です。
Kana: みっつめのしつもんです。
Both Korean 「세 번째」 and Japanese 「三つ目」 identify the third question in a sequence. This does not mean that there are only three questions in total. Rather, it identifies the third question among several.
◆ Key Differences Between Korean 「개」 and Related Quantity Expressions:
The strongest similarity between Japanese 「つ」 and Korean 「개」 is that both can count ordinary objects. For example, 「りんごを二つください」 corresponds to 「사과 두 개 주세요」, while 「パンを三つ買いました」 corresponds to 「빵 세 개 샀어요」. However, Japanese uses the native counting system 「ひとつ、ふたつ、みっつ」, whereas Korean combines native Korean numbers with a counter, producing 「한 개、두 개、세 개」. Korean 「개」 can also continue to be used for quantities of eleven or more.
If the items being counted are questions, reasons, or methods, Japanese can continue using 「つ」, while Korean chooses between 「하나」「개」 and 「가지」 depending on the situation. For example, 「質問が一つあります」 can usually be expressed as 「질문이 하나 있어요」, while 「理由は三つあります」 can be expressed as 「이유가 세 가지 있어요」. These sentences can all be translated into Chinese using expressions such as 「一個」 or 「三個」, but Korean does not necessarily use 「개」 in every case.
The two languages also differ in how they form expressions for asking about quantities, distributing items, and indicating order. Japanese 「いくつ」 corresponds to Korean 「몇 개」, 「一つずつ」 can correspond to 「한 개씩」 or 「하나씩」, and 「二つ目」 often corresponds to 「두 번째」. Therefore, Japanese 「つ」 cannot always be translated as Korean 「개」. You need to distinguish whether the sentence is counting objects, asking about quantities, distributing items, or indicating a position in a sequence.
The Japanese counter 「つ」 is very common in shopping, ordering food, and everyday conversation. From 「一つ（ひとつ）」 to 「九つ（ここのつ）」, each number has a fixed pronunciation, while ten is pronounced 「とお」 without adding 「つ」. In particular, expressions containing the small 「っ」, such as 「三つ（みっつ）」 and 「六つ（むっつ）」, deserve extra attention during pronunciation practice to help avoid misunderstanding quantities.
When using these expressions, start by considering what you are counting. Rice balls, cakes, and questions can be counted with 「つ」, but tickets generally use 「枚」, books use 「冊」, and drinks use 「杯」 when you want to specify the number of cups. Meanwhile, 「いくつ」 asks "how many," 「一つずつ」 expresses distribution one item at a time, and 「二つ目」 indicates order. Understanding these uses through complete sentences makes it easier to decide when to use 「つ」 and when another counter is needed.
FAQs
「つ」 is a Japanese counter commonly used for ordinary objects such as apples, rice balls, and snacks. It can also count abstract things such as questions, reasons, and options. In Chinese, it may be translated using measure words such as 「個」「份」 or 「項」, depending on what is being counted.
They are pronounced 「ひとつ、ふたつ、みっつ」, respectively, using the native Japanese counting system. You cannot simply pronounce them 「いちつ、につ、さんつ」. 「三つ」 contains the small 「っ」, which indicates a brief pause in pronunciation.
The sequence is 「ひとつ、ふたつ、みっつ、よっつ、いつつ、むっつ、ななつ、やっつ、ここのつ、とお」. The written forms from one to nine all include 「つ」, while ten is written 「十」 and pronounced 「とお」.
Both can express ten items, but they belong to different counting systems. 「十（とお）」 uses the native Japanese counting system, while 「十個（じゅっこ／じっこ）」 uses the counter 「個」. When counting everyday objects such as eggs, 「十個」 is generally more explicit.
No. The native counting system using 「つ」 only goes up to 「十（とお）」. You cannot continue adding 「つ」 for eleven or higher. For example, to say there are eleven apples, you can use 「りんごが十一個あります」, pronounced 「じゅういっこ」.
Yes. For example, 「質問が一つあります」 means "I have one question," while 「理由は三つあります」 means "There are three reasons." 「つ」 is not limited to physical objects; it can also count questions, conditions, methods, and other abstract things.
A common word order is "noun + が／を + quantity + verb," as in 「りんごを二つ買いました」. If the quantity directly modifies a noun, you need to add 「の」, as in 「二つのりんご」. You cannot simply write 「二つりんご」.
「いくつ」 means "how many" and is used to ask about the number of objects or things. For example, 「りんごはいくつありますか」 asks how many apples there are. 「いくつ」 can also be used to ask someone's age, but you should be mindful of the situation when asking an adult you do not know well about their age.
「いくつ」 mainly asks about quantity, while 「いくら」 mainly asks about price. For example, 「りんごはいくつありますか」 asks how many apples there are, whereas 「りんごはいくらですか」 asks how much the apples cost.
「つ」 can count ordinary objects and abstract things, while 「個」 is commonly used for separate individual objects. Both 「りんごを二つ」 and 「りんごを二個」 sound natural. However, the counting system using 「つ」 only goes up to ten, while 「個」 can also count quantities of eleven or more.
Not in every case. Paper and tickets are generally counted with 「枚」, pens and bottles with 「本」, books with 「冊」, and cups of drinks with 「杯」. For example, 「本を二冊買う」 follows conventional Japanese counting usage for books more closely than 「本を二つ買う」.
「一つずつ」 means one per person, one at a time, or handling things individually, as in 「一人一つずつ取ってください」. 「二つ目」 indicates the second item in a sequence, as in 「二つ目の信号」. The former describes distribution, while the latter describes order.
Yes. For example, 「ケーキを二つお願いします」 means ordering two servings of cake, while 「カレーを一つください」 means ordering one serving of curry. If you want to specify the number of cups of a drink, you can use 「杯」, as in 「コーヒーを二杯ください」.
Both can count ordinary objects. Japanese uses 「一つ、二つ、三つ」, while Korean uses 「한 개、두 개、세 개」. This Japanese counting system only goes up to ten, while Korean 「개」 can continue to be used for quantities of eleven or more. Korean also commonly uses 「가지」 when counting things such as reasons and methods.
