Why Grammar Is Central to JLPT N4

At the N4 level, grammar moves beyond simple sentence structures into more nuanced territory. You'll be expected to understand cause-and-effect relationships, express ability and desire, use conditional forms, and describe more complex sequences of actions. Mastering these patterns is the backbone of passing N4's Language Knowledge section.

Key Grammar Patterns for N4

Below are some of the most frequently tested grammar structures at the N4 level, organized by function.

Expressing Ability

  • 〜ことができる — Can do / able to do
    Example: 日本語を話すことができます。(I can speak Japanese.)
  • 〜られる (potential form) — The verb-based way to express ability
    Example: この漢字が読める。(I can read this kanji.)

Expressing Desire

  • 〜たい — Want to do (speaker's desire)
    Example: 日本に行きたい。(I want to go to Japan.)
  • 〜てほしい — Want someone else to do something
    Example: 早く来てほしい。(I want you to come early.)

Conditionals

  • 〜たら — If / when (after something happens)
    Example: 家に帰ったら、電話してください。(When you get home, please call me.)
  • 〜ば — If (hypothetical, often used for advice or general truths)
    Example: 勉強すれば、合格できる。(If you study, you can pass.)
  • 〜と — If / when (natural result or habitual action)
    Example: 右に曲がると、駅があります。(If you turn right, there's a station.)

Giving and Receiving

The giving/receiving grammar system is one of the trickier aspects of N4, but it's heavily tested.

  • 〜てあげる — To do something for someone (you give the action)
  • 〜てもらう — To have someone do something for you (you receive the action)
  • 〜てくれる — Someone does something for you (with the nuance of a favor)

Expressing Change and State

  • 〜になる / 〜くなる — To become (noun/na-adj → になる; i-adj → くなる)
    Example: 日本語が上手になった。(My Japanese has improved.)
  • 〜ている — Ongoing action or resultant state (already known from N5, but depth increases at N4)

Obligation and Permission

  • 〜なければならない / 〜なきゃ — Must / have to
  • 〜てもいい — It's okay to / may
  • 〜てはいけない — Must not / prohibited

How to Study These Patterns Effectively

  1. Learn in context, not isolation. Memorizing patterns as abstract rules is ineffective. Always study them with example sentences.
  2. Create your own sentences. After seeing an example, write 2–3 sentences about your own life using the same pattern.
  3. Use a grammar reference book. A Dictionary of Basic Japanese Grammar (Makino & Tsutsui) is widely recommended for N4–N3 learners.
  4. Drill with JLPT practice questions. Official past questions and practice workbooks show exactly how patterns are tested.
  5. Review through spaced repetition. Use Anki decks specifically built for JLPT N4 grammar.

Vocabulary Tips for N4

N4 requires roughly 1,500 words. Build vocabulary systematically by learning words in thematic groups (food, transportation, emotions, work) and always note the part of speech. Understanding whether a word is a する-verb, i-adjective, or na-adjective will directly affect which grammar patterns you can use with it.

Final Thoughts

N4 grammar is where Japanese starts to feel genuinely expressive. These patterns let you describe nuanced situations, and mastering them sets you up not just for the test, but for real communication. Invest time in understanding the why behind each pattern, not just the form.
