Once you reach N3 in Japanese, you often run into a very noticeable gap: you recognize the vocabulary, you have memorized the attachment patterns, and each grammar pattern seems understandable when you look at it on its own. But once it appears in an actual question or passage, you may no longer know why that particular form is used or why another one cannot replace it. N3 grammar relies more heavily on clues from the surrounding context, such as who made a decision, whether a certain outcome was planned from the beginning or only came about later, and what the speaker is basing a judgment on. Many of these distinctions look very similar once translated into Chinese, so memorizing a single line of Chinese meaning becomes increasingly inadequate at this level.

There is also no official fixed list of JLPT N3 grammar points. Since the revised test format was introduced in 2010, the JLPT has no longer published an itemized 「出題基準」 listing vocabulary, kanji, and grammar points. As a result, N3 textbooks on the market contain different numbers of grammar items depending on how they classify them. What follows is not an “official N3 grammar list,” but a collection of patterns commonly encountered when preparing for N3, along with basic forms that continue to appear in grammar, reading, and listening at this level. Rather than focusing on exactly how many grammar points there are, it is more useful to first understand what kind of relationship each group of patterns expresses in a sentence, then go back and memorize their attachment patterns.

What Is the Difference Between Japanese N3 and N4? N3 Grammar Relies More on Context

Moving from N4 to N3 does not mean that Japanese suddenly switches to a completely different grammar system. The more noticeable difference is that N3 questions contain more similar expressions, and the same Chinese translation may correspond to several different Japanese forms. At the N4 level, common patterns such as 「〜たい」「〜ている」「〜たことがある」 usually reveal their basic function even when viewed in a single sentence. At N3, meanings such as “decision,” “cause,” “inference,” and “change” are divided more finely, which makes the information provided by the surrounding sentences increasingly important.

For example, both 「来年、日本へ留学することにしました」 and 「来月から大阪へ転勤することになりました」 may be translated into Chinese using words such as “decide” or “be decided.” However, the first sentence foregrounds the subject’s own choice, while the second focuses on the arrangement that was ultimately established. Likewise, 「読むようにしています」 and 「読めるようになりました」 may both produce Chinese translations involving ideas such as “start,” “become,” or “develop a habit,” but in Japanese they describe two different things: an action deliberately maintained and a change that has already taken place.

The JLPT’s official description of N3 is not simply about “memorizing another batch of grammar.” In reading, learners begin to need to understand passages on everyday topics, grasp the gist of newspaper headlines, and follow somewhat more difficult material when it has been rephrased. Listening also includes connected conversations delivered at a speed closer to natural speech. The grammar itself still has to be learned, but after memorizing the forms, you also need to put them back into context and determine how they function there.

What Grammar Appears at Japanese N3? Start by Dividing Common Patterns into 14 Functions

If all N3 grammar is arranged in textbook order, it can easily turn into a long list of forms that feel familiar but are hard to place in actual usage. A more manageable approach is to first identify whether a pattern deals with time, cause, decisions, inference, or another relationship between parts of a sentence. Some of the forms below are common new patterns at N3, while others are foundational grammar already encountered at N4 that continues to appear repeatedly alongside other forms at N3.

Function	Common representative grammar	What to check first
Time and duration	「うちに」「間／間に」「最中に」「たびに」「ところだ」「たところ」	Does something continue throughout the entire period, or does one action occur within that period?
Decisions and arrangements	「ことにする」「ことになる」「ことになっている」	Did the subject decide it personally, or is it an arrangement or rule that was ultimately established?
Habits and changes of state	「ようにする」「ようになる」	Is the subject deliberately maintaining an action, or has an ability, habit, or state actually changed?
Causes and reasons	「おかげで」「せいで」「ために」「ので」「から」	How is the result caused by the preceding event evaluated, and is the tone subjective or relatively neutral?
Prediction and judgment	「はずだ」「はずがない」「ようだ」「らしい」「みたいだ」	Is the judgment based on known information, observation, or a less definite inference?
Hearsay and appearance	「そうだ」「らしい」「ようだ」「みたいだ」	Is the information something the speaker heard, or a judgment made from what is directly observed?
Understanding and conclusions	「わけだ」「わけがない」「ということだ」	Is the speaker reaching a conclusion after understanding the circumstances, or directly denying a possibility?
Limitation and emphasis	「だけ」「しか〜ない」「ばかり」「こそ」「さえ」	Is the expression simply limiting the range, or does it also convey an attitude such as “of all things,” “even,” or “precisely”?
Topic, target, and standpoint	「について」「に対して」「にとって」「によって」「によると」	Is the preceding noun a topic, target, standpoint, method, or information source?
Comparison and degree	「ほど」「くらい／ぐらい」「ば〜ほど」「ほど〜ない」	Does it simply express degree, or does it make a relative comparison between two things?
State and simultaneous actions	「まま」「ながら」「ついでに」「っぱなし」	Is the original state maintained, and are two actions happening simultaneously or incidentally?
Conditions and hypotheses	「と」「ば」「たら」「なら」「ないと」	Is the condition a natural consequence, general rule, hypothesis, or a condition proposed in response to previous information?
Contrast and concession	「のに」「ても」「くせに」	Does the result differ from what was originally expected, and does the speaker express dissatisfaction?
Purpose and intention	「ために」「ように」「つもりだ」「予定だ」	Is something being pursued directly as a purpose, is a particular result being aimed for, or is the sentence expressing an intention or plan?

This table works better as an index than as something to memorize cell by cell. 「ために」 appears under both cause and purpose, while 「そうだ」 has one use based on outward appearance and another that reports information heard from someone else. N3 frequently introduces this kind of grammar: the form looks the same, but differences in what comes before or after it, or in the source of the information, change its meaning.

Once you are comfortable with the three Japanese verb groups and conjugation and the て-form, you can begin reading this table from the “function” column instead of recalculating verb forms every time you see a pattern. The part that usually causes difficulty is not the conjugation itself, but how several forms within the same category differ from one another.

How Do You Tell Similar N3 Grammar Apart? Similar Chinese Meanings Do Not Make the Forms Interchangeable

Many N3 questions are difficult because every option looks familiar. At that point, do not rush to translate all four choices into Chinese, because they may still look identical after translation. Instead, look at what the sentence is dealing with: where the decision came from, whether the result is viewed positively or negatively, where the information came from, and whether something is a direct purpose or a desired outcome.

Common pair or group	Common Chinese translation	What you actually need to distinguish
「ことにする／ことになる」	decide, be decided	Whether the decision was actively made by the subject
「ようにする／ようになる」	start, become, develop a habit	Whether the subject is deliberately adjusting the action
「おかげで／せいで」	because of, thanks to	How the speaker evaluates the result that follows
「はずだ／わけだ」	should, so that explains it	Whether the speaker predicts a result from information or reaches a conclusion after understanding the circumstances
「そうだ／らしい／ようだ」	seem, apparently, I hear	Whether the information comes from appearance, hearsay, or the speaker’s own judgment
「ために／ように」	in order to	Whether the preceding outcome can be directly controlled by the subject

「ことにする／ことになる」: A Decision You Make Yourself or an Arrangement That Is Ultimately Established

Both 「ことにする」 and 「ことになる」 are commonly translated into Chinese as “decide,” but the difference lies in what the sentence foregrounds. 「ことにする」 usually describes the subject making a choice or resolution. 「ことになる」 explains what the situation ultimately came to be, and the person who made the decision does not necessarily appear in the sentence. The arrangement may have been produced by a company, school, organization, or other circumstances.

Comparison	「ことにする」	「ことになる」
Common Chinese meaning	decide to…	be decided that…, be arranged to…
Focus	A choice made by the subject	The result or arrangement ultimately established
Subject’s volition	Relatively clear	Not particularly emphasized
Common situations	Personal decisions and resolutions	Company arrangements, rules, agreements, developments in circumstances
How to judge	Who decided to do this?	What was ultimately decided or arranged?

Both 「ことにする」 and 「ことになる」 can be translated as “decide,” but they look at the situation from different angles. 「ことにする」 foregrounds the person making the decision and indicates that the person considered the options and chose what to do. 「ことになる」 instead focuses on the result that was ultimately settled. It may come from a company, school, group discussion, or other circumstances, and the sentence does not necessarily identify who made the decision. If the situation is that someone will work in Osaka from next month, 「ことにする」 can be used if the person personally chose the transfer. If the sentence is reporting an already confirmed company transfer, 「ことになる」 is more natural.

• Example: 健康のために、今年からお酒を飲まないことにしました。
  Kana: けんこうのために、ことしからおさけをのまないことにしました。
  Translation: For my health, I decided to stop drinking alcohol starting this year.
  Not drinking is a decision made by the subject, so 「ことにする」 is used. The sentence is not describing an external rule, but a choice made after consideration to change one’s lifestyle.
• Example: 来週の会議はオンラインで行うことになりました。
  Kana: らいしゅうのかいぎはオンラインでおこなうことになりました。
  Translation: It has been decided that next week’s meeting will be held online.
  The sentence simply reports that the meeting has ultimately been set to take place online, without needing to identify a particular person who made the decision, so 「ことになる」 is used.

Suppose the final result in both cases is “starting next month, I will work at the Tokyo branch.” The two sentences can refer to the same real-world outcome, but they present it from different perspectives. 「ことにしました」 sounds as though the speaker considered the matter and personally chose to go to Tokyo. 「ことになりました」 does not specify who decided it and simply reports that the arrangement has now been finalized. The latter is more common for situations such as company transfer notices or group decisions.

• Example: 来月から東京支社で働くことにしました。
  Kana: らいげつからとうきょうししゃではたらくことにしました。
  Translation: I decided to start working at the Tokyo branch next month.
  This sentence focuses on the decision made by the subject and sounds as though the person considered the matter and chose this course of action.
• Example: 来月から東京支社で働くことになりました。
  Kana: らいげつからとうきょうししゃではたらくことになりました。
  Translation: It has been decided that I will start working at the Tokyo branch next month.
  The outcome is still working in Tokyo, but this sentence only reports that the arrangement has been finalized. It may be the result of a company transfer or some other external decision.

「ようにする／ようになる」: Deliberately Maintaining an Action or Actually Reaching a New State

「ようにする」 indicates consciously adjusting or maintaining a particular behavior. It commonly appears when forming habits, reminding yourself to do something, or deliberately avoiding something. 「ようになる」 describes a new state that develops over time in an ability, habit, or behavior. With the former, you can still see the subject’s intention to keep doing something; the latter is more like looking back and describing how “things have now become this way.”

Comparison	「ようにする」	「ようになる」
Common Chinese meaning	try to…, deliberately…	become…, come to be able to…
Focus	Consciously adjusting behavior	A new state formed through change
Subject’s volition	Clear	Not necessarily emphasized
Common situations	Habits, precautions, avoiding certain actions	Improved abilities, established habits, changes of state
How to judge	Is the person still consciously trying to do it?	Has this already become the new state?

「ようにする」 indicates that the subject is still consciously adjusting or maintaining an action. It often appears with lifestyle habits, precautions, or deliberate avoidance. 「ようになる」 compares the past with the present and indicates that an ability, habit, or behavior has changed over time. The former still reflects the subject’s ongoing effort, while the latter describes the new state that has already formed.

• Example: 食事の後は、すぐ歯を磨くようにしています。
  Kana: しょくじのあとは、すぐはをみがくようにしています。
  Translation: After meals, I make a point of brushing my teeth right away.
  This habit requires the subject to keep acting consciously, so 「ようにしている」 is used, with the focus on the behavior still being maintained now.
• Example: 一人暮らしを始めてから、自分で料理するようになりました。
  Kana: ひとりぐらしをはじめてから、じぶんでりょうりするようになりました。
  Translation: After I started living alone, I began cooking for myself.
  The speaker did not previously have this habit, but after beginning to live alone, cooking independently gradually became part of the speaker’s lifestyle. 「ようになる」 therefore describes the change from before to after.

Both sentences can appear in the context of waking up early. 「6時に起きるようにしています」 means the person consciously tries to maintain a routine of getting up at six, although there may still be occasional days when they fail. 「6時に起きるようになりました」 looks back at the difference between the past and present and describes the fact that getting up around six has now become the person’s normal state.

• Example: 毎朝六時に起きるようにしています。
  Kana: まいあさろくじにおきるようにしています。
  Translation: I make a point of getting up at six every morning.
  The sentence still carries the sense of deliberately doing this, with the focus on currently maintaining the habit.
• Example: 最近、毎朝六時に起きるようになりました。
  Kana: さいきん、まいあさろくじにおきるようになりました。
  Translation: Recently, I’ve started getting up at six every morning.
  The sentence describes a new habit that was not true before but has now become established.

「おかげで／せいで」: The Cause May Be the Same, but the Result Is Evaluated Differently

Both 「おかげで」 and 「せいで」 can present the preceding event as a cause, but each expression also brings in the speaker’s evaluation. 「おかげで」 normally indicates that the cause led to a favorable result and often carries a sense of gratitude. 「せいで」 is used for unfavorable results and may convey complaint, blame, or regret. In special cases, 「おかげで」 can also be deliberately used before a bad result to create irony.

Comparison	「おかげで」	「せいで」
Common Chinese meaning	thanks to…, owing to…	because of…, it’s …’s fault
Evaluation of result	Usually positive	Usually negative
Speaker’s attitude	Gratitude, benefit	Complaint, blame, regret
Can it refer to oneself?	Yes	Yes, often with self-blame
Special use	Can become ironic before a negative result	Usually directly expresses a negative evaluation

Both 「おかげで」 and 「せいで」 can explain the cause of a result, but they also incorporate the speaker’s evaluation of that result. 「おかげで」 usually follows a cause that produced a good outcome and may also express gratitude. 「せいで」 normally appears with an unwanted result and readily carries feelings of complaint, blame, or regret. When deciding between them, the key is not whether the cause itself is objectively good or bad, but how the final result is viewed.

• Example: 先生が詳しく説明してくれたおかげで、問題の意味が分かりました。
  Kana: せんせいがくわしくせつめいしてくれたおかげで、もんだいのいみがわかりました。
  Translation: Thanks to the teacher’s detailed explanation, I finally understood what the question meant.
  The teacher’s explanation produced the positive result of understanding the question, and the sentence also conveys a sense of benefit and gratitude, so 「おかげで」 is used.
• Example: 寝坊したせいで、大事な約束に遅れてしまいました。
  Kana: ねぼうしたせいで、だいじなやくそくにおくれてしまいました。
  Translation: Because I overslept, I ended up being late for an important appointment.
  Oversleeping directly caused the unwanted result of being late, and 「せいで」 also conveys regret and self-blame here.

The basic fact—“it rained, so today’s plans were canceled”—does not change. But if the speaker was already exhausted and the cancellation conveniently created time to rest, 「おかげで」 can be used. If the speaker had been looking forward to the plans for a long time and the cancellation caused disappointment, 「せいで」 is used instead. The most important point in this pair is not the objective outcome itself, but whether the speaker treats that outcome as a good thing or a bad thing.

• Example: 最近ずっと疲れていたので、雨のおかげで今日の予定がなくなって、ゆっくり休めました。
  Kana: さいきんずっとつかれていたので、あめのおかげできょうのよていがなくなって、ゆっくりやすめました。
  Translation: I had been tired for a while, so thanks to the rain canceling today’s plans, I was finally able to get some proper rest.
  Here, the cancellation of the plans actually created time to rest, so the speaker treats the rain as a favorable cause.
• Example: 楽しみにしていたのに、雨のせいで今日の予定がなくなりました。
  Kana: たのしみにしていたのに、あめのせいできょうのよていがなくなりました。
  Translation: I had been looking forward to it, but today’s plans were canceled because of the rain.
  The same cancellation is now treated as a disappointing result, so 「せいで」 is used.

「はずだ／わけだ」: Did You Expect It from the Start, or Understand It Only After Learning the Reason?

「はずだ」 and 「わけだ」 may both be translated into Chinese with expressions such as “should,” “no wonder,” or “so that explains it,” but the point at which the judgment is made differs. 「はずだ」 often uses existing knowledge, experience, or common sense to first form a judgment that “given the circumstances, this should be the case.” 「わけだ」 is often used after learning another fact and then looking back at the result in front of you, with a sense of “so that’s why this happened.”

Comparison	「はずだ」	「わけだ」
Common Chinese meaning	should…, logically ought to…	no wonder…, so that explains it
Direction of judgment	Predict a result from known information	Understand a result from an established fact
Sense of timing	Can be used before the result is confirmed	Often used after learning the reason
Speaker’s feeling	Expectation, confidence	Understanding, realization
How to judge	Given these conditions, what should happen?	After learning this fact, does the reason now make sense?

「はずだ」 usually starts from known information, experience, or common sense and works forward to the conclusion that “given these facts, this should be the case.” 「わけだ」 instead comes after learning a reason or background fact and looks back to explain a result that was already known, with a sense of “I see” or “no wonder.” Both have a basis, but 「はずだ」 moves from evidence toward a predicted result, while 「わけだ」 moves from a cause back toward an already known phenomenon.

• Example: 駅からここまで歩いて五分だから、佐藤さんももうすぐ着くはずです。
  Kana: えきからここまであるいてごふんだから、さとうさんももうすぐつくはずです。
  Translation: It only takes five minutes to walk here from the station, so Sato should be arriving soon.
  The speaker knows that Sato is coming from the station and that the walk takes only five minutes, so these conditions are used to infer that Sato should arrive soon. This is why 「はずだ」 is used.
• Example: 毎日三時間もピアノを練習しているんですか。上手なわけですね。
  Kana: まいにちさんじかんもピアノをれんしゅうしているんですか。じょうずなわけですね。
  Translation: You practice the piano for three hours every day?
  No wonder you’re so good. The speaker already knew that the other person played the piano well, then later learned the background fact that they practice for three hours every day. That new information explains the earlier observation, so 「わけだ」 expresses the realization of “now it makes sense.”

Suppose you first notice that Tanaka is very good at cooking, and only afterward learn that he used to work as a cook in France. 「はずだ」 takes the general knowledge that professional cooks are usually skilled at cooking and uses it to conclude that “then of course he should be good at cooking.” 「わけだ」 is more like hearing about his professional background and suddenly connecting it with the earlier observation: “I see—no wonder he cooks so well.”

• Example: 田中さんはフランスで料理人をしていたそうです。料理が上手なはずですね。
  Kana: たなかさんはフランスでりょうりにんをしていたそうです。りょうりがじょうずなはずですね。
  Translation: I heard Tanaka used to work as a cook in France.
  In that case, he should be good at cooking. The speaker starts from the information that Tanaka used to be a cook and applies general knowledge to infer that he should be skilled at cooking.
• Example: 田中さんはフランスで料理人をしていたそうです。なるほど、料理が上手なわけですね。
  Kana: たなかさんはフランスでりょうりにんをしていたそうです。なるほど、りょうりがじょうずなわけですね。
  Translation: I heard Tanaka used to work as a cook in France.
  I see—no wonder he’s so good at cooking. Here, “Tanaka is good at cooking” is already known. After learning about his professional background, the speaker finally understands why, so 「わけだ」 conveys a sense of realization and understanding.

「そうだ／らしい／ようだ」: They Can All Mean “Seem,” but the Information Comes from Different Sources

This group requires you to distinguish the uses of 「そうだ」 first. The comparison below concerns 「そうだ」 expressing appearance or manner, not the hearsay use of 「～そうだ」. The appearance use of 「そうだ」 commonly occurs when the speaker directly sees, smells, or senses a situation. 「ようだ」 can express an inference made after considering visible clues or other information. 「らしい」 is more often associated with information obtained indirectly. Hearsay 「そうだ」 uses a different attachment pattern; for example, 「おいしいそうだ」 means “I hear it is delicious.”

Comparison	「そうだ」 (appearance)	「ようだ」	「らしい」
Common Chinese meaning	looks…	seems…, apparently…	I hear…, apparently…
Information source	Directly seen or sensed	Judgment based on direct or indirect clues	More often indirect information
How the judgment is made	Strongly based on first impression	Inference after observation	Based on something heard or otherwise learned indirectly
Typical nuance	It looks that way right in front of you	Multiple clues lead you to believe so	From what you have heard, that seems to be the case
Note	Different attachment pattern from hearsay 「そうだ」	Can express inference and has other uses as well	Can also express “typical of…” or “having the character of…”

The 「そうだ」 here is the appearance use of 「そうだ」 and is primarily based on a state that the speaker can directly see or sense. 「らしい」 often relies on what other people say, news reports, or other indirect information. 「ようだ」 can combine what the speaker observes with other clues and then form an inference. All three may be translated into Chinese as “seems,” but the way the information is obtained and the reasoning process differ.

• Example: 空が急に暗くなってきました。雨が降りそうです。
  Kana: そらがきゅうにくらくなってきました。あめがふりそうです。
  Translation: The sky has suddenly become dark.
  It looks like it’s about to rain. The speaker directly sees the sky getting darker and feels from the immediate situation that rain is likely to start soon, so the appearance use of 「そうだ」 is used.
• Example: ニュースによると、駅前のスーパーは来月閉店するらしいです。
  Kana: ニュースによると、えきまえのスーパーはらいげつへいてんするらしいです。
  Translation: According to the news, the supermarket in front of the station is apparently closing next month.
  The information comes from a news report rather than the speaker’s own direct confirmation, so 「らしい」 expresses information learned indirectly.
• Example: 部屋の電気も消えているし、何度呼んでも返事がありません。誰もいないようです。
  Kana: へやのでんきもきえているし、なんどよんでもへんじがありません。だれもいないようです。
  Translation: The light in the room is off, and no one answers no matter how many times I call.
  It seems that no one is there. The speaker is not making a judgment based on a single visual impression, but combining several clues—“the light is off” and “there is no response”—to infer that nobody is there, so 「ようだ」 is used.

All three sentences may be translated into Chinese as something like “This cake seems delicious,” but the speaker acquired the information in different ways. 「おいしそうだ」 is most like standing in front of the cake and forming a direct impression from its appearance, cream, or fruit. 「おいしいようだ」 is closer to judging from several signs, such as seeing many people order it or buy it again. 「おいしいらしい」 is more likely to be used after hearing other people’s opinions or seeing related information.

• Example: このケーキはおいしそうです。
  Kana: このケーキはおいしそうです。
  Translation: This cake looks delicious.
  The speaker forms the direct impression “it looks delicious” from the cake’s appearance, so this is the appearance use of 「そうだ」.
• Example: みんな同じケーキを注文しています。このケーキはおいしいようですね。
  Kana: みんなおなじケーキをちゅうもんしています。このケーキはおいしいようですね。
  Translation: Everyone is ordering the same cake.
  It seems this cake is delicious. The judgment is not based only on the cake’s appearance, but on the fact that many people are ordering it, so 「ようだ」 is more appropriate.
• Example: 友達の話では、このケーキはおいしいらしいです。
  Kana: ともだちのはなしでは、このケーキはおいしいらしいです。
  Translation: According to my friend, this cake is apparently delicious.
  The information comes from a friend rather than from having eaten the cake personally, so 「らしい」 carries the sense of information obtained indirectly.

「ために／ように」: Both Can Mean “In Order To,” but They Differ in Whether the Result Can Be Directly Controlled

When expressing purpose, both 「ために」 and 「ように」 are often translated into Chinese as “in order to,” but they focus on different aspects of the sentence. 「ために」 more directly treats the preceding event as a goal actively pursued by the subject, so it commonly appears with volitional actions. 「ように」 focuses instead on making a certain result or state come about, and the preceding form is often a potential form, intransitive verb, or negative form.

Comparison	「ために」	「ように」
Common Chinese meaning	in order to…	so that one can…, so as not to…
Focus	Directly pursuing a particular goal	Aiming for a certain result to come about
Volitionality	Relatively strong	The result itself may not be fully controllable
Common combinations	Volitional verbs	Potential forms, intransitive verbs, ない-forms
How to judge	Can the subject directly treat the preceding event as an action goal?	Is the preceding event more like a desired state or outcome?

The purpose use of 「ために」 normally sets the preceding event directly as a goal the subject consciously pursues, so it often combines with highly volitional actions. 「ように」 is frequently used when the aim is for a particular state to come about, especially with potential forms, negative forms, or results that cannot be achieved by willpower alone. Both may be translated into Chinese as “in order to,” but 「ために」 is more like acting toward a clearly defined goal, while 「ように」 looks at the state the speaker hopes will ultimately be realized.

• Example: 将来自分の店を開くために、料理の学校に通っています。
  Kana: しょうらいじぶんのみせをひらくために、りょうりのがっこうにかよっています。
  Translation: I am attending culinary school in order to open my own restaurant in the future.
  “Opening my own restaurant” is a clear goal set by the subject, and attending culinary school is an action taken toward that goal, so 「ために」 is used.
• Example: 大事な予定を忘れないように、スマートフォンにメモしておきました。
  Kana: だいじなよていをわすれないように、スマートフォンにメモしておきました。
  Translation: I made a note on my smartphone so that I would not forget the important appointment.
  “Not forgetting” is a desired outcome rather than an action that is directly carried out as the purpose, so 「ように」 is used. Writing the appointment down on the phone makes the state of “not forgetting” more likely to be achieved.

Suppose the purpose of studying every day is to pass N3. 「N3に合格するために」 directly treats “passing N3” as the goal being actively pursued, so the intention is relatively explicit. 「N3に合格できるように」 focuses on the result of “being able to pass N3,” so it uses the potential form 「できる」. The nuance is closer to making an effort so that this outcome has a chance to become reality.

• Example: N3に合格するために、毎日日本語を勉強しています。
  Kana: エヌスリーにごうかくするために、まいにちにほんごをべんきょうしています。
  Translation: I study Japanese every day in order to pass N3.
  “Passing” is directly established as the purpose of the action, and the studying that follows is carried out toward that goal.
• Example: N3に合格できるように、毎日日本語を勉強しています。
  Kana: エヌスリーにごうかくできるように、まいにちにほんごをべんきょうしています。
  Translation: I study Japanese every day so that I can pass N3.
  This sentence focuses on the final result of being able to pass, so 「できるように」 is used. The actual action is still studying every day, but the sentence is not looking at the purpose itself so much as the hoped-for outcome.

What Order Should You Study N3 Grammar In? Strengthen Conjugation First, Then Work Through Similar Patterns by Function

A complete overview of N3 grammar contains many items, but it is not well suited to memorizing straight from the first cell of a table to the last. If you still have to work out the plain form, ない-form, た-form, and て-form step by step, then when you encounter 「ことになる」「ようにする」「はずだ」, it is easy to spend all your attention on how the form attaches. In that situation, reviewing basic conjugation first is usually more efficient than forcing yourself to memorize even more N3 patterns. If the difference between 「は」 and 「が」 is still uncertain, that will also directly affect your ability to determine what information a sentence is actually talking about when reading.

Once conjugation is no longer a problem, you can work through grammar one functional group at a time. For time expressions, first compare 「間／間に」「うちに」「最中に」. For decisions and changes, group 「ことにする／ことになる」 with 「ようにする／ようになる」. Then compare causes through 「おかげで／せいで／ために」. Within each group, do not memorize only the Chinese translations. Keep at least one diagnostic question in mind. When you see 「おかげで／せいで」, ask first whether the following result is being treated as a good thing or a bad thing. With 「はずだ／わけだ」, check whether the sentence is predicting an outcome or reacting to a newly learned reason with “so that explains it.”

Limiting expressions can be approached in the same way. The nuance difference between 「だけ」 and 「しか」cannot be reduced to memorizing both as “only.” 「しか」 must be used with a negative form and often conveys a sense that the range is smaller than expected. 「だけ」 simply marks off a range. With 「こそ」「さえ」, the Chinese translation shifts again to expressions such as “precisely” or “even,” but what matters is still which part the speaker is singling out for special emphasis.

After you finish organizing one group of grammar, put it back into a short passage or listening exercise and look at it again. This makes it easier to identify the real problem than copying an attachment chart ten times in a row. Sometimes the difficulty is not the grammar at all, but the fact that the subject has been omitted. At other times, every word is familiar, but you failed to notice that the previous sentence had already explained where the decision came from. Situations like these become common at N3.

N3 Grammar Commonly Heard While Traveling in Japan: How to Talk About Habits and Prearranged Plans

When traveling in Japan, 「ことになっている」 and 「ようにしている」 often appear in already scheduled itineraries, rules at shops or accommodation facilities, and personal habits. Both patterns may become something as simple as “do” or “have” in Chinese translation, but Japanese is not really focusing on the surface action. The key is why the situation continues to exist in its current form. 「ようにしている」 is usually connected with a habit the person consciously maintains, while 「ことになっている」 is more commonly used to explain an already finalized arrangement or an existing rule. When you hear these forms while traveling, first check whether the action is something an individual consciously does or something that the hotel, shop, or itinerary has already established.

▌Situation ①｜Explaining Food You Normally Avoid at a Restaurant

A：辛いものは大丈夫ですか。
　　からいものは だいじょうぶですか。
　　Are you okay with spicy food?

B：夜は辛いものを食べないようにしています。
　　よるは からいものを たべないように しています。
　　I try not to eat spicy food at night.

📌 Grammar Point: 「～ないようにしています」 indicates that someone consciously avoids a particular action as a regular practice. This sentence does not mean “I’m not eating spicy food tonight.” It explains a dietary habit that the person normally maintains. If the speaker simply does not want spicy food right now, they can say 「今日は辛いものを食べません」. Using 「食べないようにしています」 adds the sense of deliberately maintaining the habit over time.

▌Situation ②｜Confirming the Next Day’s Departure Time at a Hotel

A：明日の出発は何時ですか。
　　あしたの しゅっぱつは なんじですか。
　　What time do we leave tomorrow?

B：朝七時に出発することになっています。
　　あさ しちじに しゅっぱつすることに なっています。
　　The arrangement is to leave at seven in the morning.

📌 Grammar Point: 「ことになっています」 indicates an arrangement that has already been finalized. The staff member is not deciding on a seven o’clock departure at the moment they answer the question. The original itinerary, tour schedule, or accommodation shuttle time has already been set, so 「ことになっています」 is used to describe the existing arrangement. If the person had only just decided personally to leave at seven, it would be closer to 「七時に出発することにしました」.

▌Situation ③｜Checking the Rules at an Onsen Facility

A：タオルをお風呂に入れてもいいですか。
　　タオルを おふろに いれても いいですか。
　　Can I put my towel in the bath?

B：タオルは湯船に入れないことになっています。
　　タオルは ゆぶねに いれないことに なっています。
　　The rule is that towels must not be put in the bath.

📌 Grammar Point: In addition to established schedules, 「ことになっています」 is also commonly used to explain existing rules. This sentence is not expressing a staff member’s personal wish that guests keep towels out of the bath. It is explaining a rule that the facility already has. When a scope marker such as 「このホテルでは」「この店では」「館内では」 appears together with 「ことになっています」, it can usually be understood as “this is the rule here.”

Cultural Notes:

1. In explanations of itineraries at Japanese hotels, ryokan, or on group tours, the person who made the decision is often omitted. A sentence such as 「朝七時に出発することになっています」 does not need to specify whether the travel agency, tour leader, or hotel arranged it, because the point is simply to inform you of what has already been decided. When you encounter 「ことになっている」, you do not necessarily need to search for a specific decision-maker first. It is usually quicker to see whether the sentence is explaining an established arrangement or rule.
2. 「ようにしています」 generally leans more toward personal habits and should not automatically be used for rules. For example, 「夜はコーヒーを飲まないようにしています」 means that the person consciously tries to avoid coffee at night. If a hotel has a rule prohibiting smoking in guest rooms, an expression such as 「客室ではタバコを吸わないことになっています」 would be used instead. The former is behavior the person maintains personally; the latter is a rule already established for the location.
3. The Chinese translation of 「ことになっています」 changes with the context, and it does not always need to be translated as “rule.” For a hotel shuttle, it might be translated as “the arrangement is…”; for a company or school system, it may become “the rule is…”; for a tour meeting time, it may simply be translated as “scheduled.” The Japanese pattern itself consistently focuses on the fact that “this is how things are currently set,” while Chinese can be adjusted naturally to the actual situation.

How Does Japanese 「ようになる」 Compare with Korean 「-게 되다」?

Japanese 「ようになる」 and Korean 「-게 되다」 can both describe a change after which an ability, habit, or behavior that did not exist before comes to exist. This makes them easy to compare in situations such as “become able to do something” or “later start doing something.” For example, if someone originally could not read kanji but gradually became able to, or previously skipped breakfast but began eating it every day after starting work, both languages can use these forms to describe the change between the earlier and later state. However, Korean 「-게 되다」 has a broader range than Japanese 「ようになる」 and is also commonly used when work arrangements, the environment, or other circumstances cause something to ultimately turn out a certain way. In those cases, Japanese does not necessarily use 「ようになる」 and may instead use 「ことになる」.

◆ Similar Grammar: 「-게 되다」

• Example: 한자를 조금씩 읽을 수 있게 됐어요.
  Romanization: han-ja-reul jo-geum-ssik il-geul su it-ge dwae-sseo-yo.
  Translation: I gradually became able to read some kanji.
  The ability to read kanji was not there before, but after some time it became possible. This kind of change in ability is very close to the Japanese 「漢字が少しずつ読めるようになりました」.
• Example: 회사에 다니기 시작하면서 아침을 꼭 먹게 됐어요.
  Romanization: hoe-sa-e da-ni-gi si-jak-ha-myeon-seo a-chim-eul kkok meok-ge dwae-sseo-yo.
  Translation: After I started working, I began making sure to eat breakfast every morning.
  This is not a change in ability, but a new habit that formed after the person’s living environment changed. In Japanese, you can say 「会社に通い始めてから、毎朝必ず朝ご飯を食べるようになりました」, which similarly compares the person’s behavior before and now.
• Example: 다음 달부터 부산에서 근무하게 됐어요.
  Romanization: da-eum dal-bu-teo bu-san-e-seo geun-mu-ha-ge dwae-sseo-yo.
  Translation: It has been decided that I will start working in Busan next month.
  Here, 「-게 되다」 does not describe gradually developing a habit. It reports that a work arrangement has ultimately been settled in this way. In Japanese, 「来月から釜山で働くことになりました」 is more natural than 「働くようになりました」, which also shows that 「-게 되다」 cannot always be replaced directly with 「ようになる」.

◆ Core Difference Between Japanese 「ようになる」 and Korean 「-게 되다」:

The easiest cases for directly comparing the two are changes in abilities, habits, or behavior from an earlier state. Japanese 「ようになる」 mainly looks at the pattern “it was not like this before, but later it became this way.” Korean 「-게 되다」 is used not only for this kind of change, but also very frequently for results that arise from external arrangements, triggers, or developments in circumstances. When you encounter 「-게 되다」, first determine whether the sentence is describing a change in ability or habit, or explaining how a situation ultimately developed. If it is the latter, Japanese does not necessarily use 「ようになる」 and may require an expression such as 「ことになる」 instead.

Korean 「-게 되다」 has a somewhat broader range than Japanese 「ようになる」 and also frequently appears when a result is produced by circumstances, a trigger, or external conditions. Some sentences may therefore carry the sense that the result “was not entirely the subject’s own active choice,” but 「-게 되다」 should not simply be treated as a Korean passive construction in every case. When using it to understand Japanese 「ようになる」, the two can first be connected through the shared idea of “a change of state,” but when actually forming sentences, you still need to return to the respective usage rules of Japanese and Korean.

Japanese N3 grammar may look like it contains a large number of items, but some of them are simply more finely divided versions of forms you already know. At N4, you can begin by remembering broad meanings such as “only,” “because,” “become,” and “decide.” Once you reach N3, those same Chinese words gradually split into distinctions such as “who made the decision,” “how the information was obtained,” “how the result is evaluated,” and “whether the situation actually changed.” This is also why memorizing a longer and longer grammar list does not necessarily make the questions easier.

When reviewing, you can use this N3 grammar overview as an index. If you encounter an unfamiliar pattern, first identify which functional group it belongs to, then compare it with the closest form in the same group. If you already know what a pattern means but keep choosing the wrong answer, you do not need to memorize its definition again. Go back to the surrounding context and look for the condition you overlooked. Many of the distinctions that truly separate similar N3 grammar patterns are hidden in details like these.
