JLPT N5 Grammar: The Core Points That Actually Matter

Forget the 100-item list. Eight grammar systems carry the entire N5 - master these and the rest fall into place.

Published July 7, 2026 · 12 min read

N5 grammar looks like a wall of ~100 patterns, but it’s really eight systems: the copula (です/だ), particles, existence verbs (あります/います), the ます-form, the te-form, the ~たい want-form, invitations (ましょう/ませんか), and adjective conjugation. Learn these deeply - inside full example sentences, reviewed with spaced repetition - and you can decode almost every N5 sentence, because the rest are variations.

Here is the trap almost every beginner falls into: they open an N5 grammar list, see 80–100 items, and try to memorize them one flashcard at a time. Three weeks later they can recite “~てもいいです means permission” but freeze the moment they have to use it. The list isn’t wrong - it’s just badly organized for how the brain actually acquires grammar.

The truth the JLPT statistics reveal is that N5 grammar is lopsided. A small number of core structures appear again and again, both on the exam and in real Japanese, while the long tail of “patterns” are just those cores in a new costume. This guide ranks the points by leverage, then teaches each one the way it should be learned: with real sentences, furigana, full translations, and the exact mistakes that cost points.

The N5 Grammar Priority Map

If your study time is limited, spend it top-down. These eight systems, in this order, give you the most comprehension and exam points per hour.

#Grammar SystemWhy It Carries the ExamLeverage
1Copula です / だEvery noun-based statement, question, and negationS
2Core particles は・が・を・に・でThey define who does what to whom - sentence skeletonS
3Te-form 〜てRequests, permission, prohibition, states, sequencesS
4ます-form & verb groupsPresent, negative, and past of every verbA
5Existence あります / いますLocation, possession, “there is” - and the living/non-living splitA
6Adjectives い / な conjugationDescription, negation, past - a second conjugation engineA
7~たい (want to)Expressing desire; also builds toward N4 formsB
8ましょう / ませんか (invite)Suggestions and invitations - the social coreB

1. The Copula です / だ: The Spine of Every Noun Sentence

Before verbs, before adjectives, Japanese lets you say “A is B” with a noun and the copula. Master its four forms (non-past affirmative/negative, past affirmative/negative) and you can already build hundreds of sentences.

Noun + です
わたし学生がくせいです。わたしは がくせいです。I am a student.
Negative: じゃありません
これはわたしほんじゃありません。これは わたしの ほんじゃ ありません。This is not my book.

Formality ladder: じゃありません (spoken polite) < ではありません (written polite) < じゃない (plain). All three mean the same “is not.”

Past: でした
昨日きのうやすみでした。きのうは やすみでした。Yesterday was a day off.
Common mistake: Using です after an い-adjective - たかいです is fine, but たかいでした is wrong. The past goes inside the adjective: たかかったです (it was expensive). です never carries the tense for い-adjectives.

2. The Five Particles That Build Every Sentence

Particles are the grammar of Japanese. If word order is loose, particles are what tell you who is the subject, what is the object, and where the action happens. These five do 80% of the work at N5.

ParticleRoleMicro-example
Topic (“as for…”)わたしは… - as for me
Subject / new infoあめる - rain falls
Direct objectごはんをべる - eat rice
Time / destination / target7時しちじきる - wake at 7
Place of action / meansバスでく - go by bus
に vs で (the classic trap)
図書館としょかん勉強べんきょうします。としょかんで べんきょうします。I study at the library. (で = where an action happens)
図書館としょかんほんがあります。としょかんに ほんが あります。There are books in the library. (に = where something exists)

Rule of thumb: で marks the stage where an action is performed; に marks a static location of existence or the end-point of movement. Verb of action → で. Verb of existence/arrival → に.

The は-vs-が split deserves its own study session - it’s the particle question learners struggle with the longest. We break it down fully in は vs が: The Particle That Confuses Every Beginner.

3. The Te-Form: The Most Important Conjugation You’ll Ever Learn

If N5 grammar had a keystone, this is it. The te-form itself has no fixed meaning - it’s a connector - but it unlocks an entire family of patterns and is the doorway to almost all N4 grammar.

~てください - request
ちょっとってください。ちょっと まってください。Please wait a moment.
~てもいいです - permission
ここで写真しゃしんってもいいです。ここで しゃしんを とっても いいです。You may take photos here.
~てはいけません - prohibition
ここでたばこをってはいけません。ここで たばこを すっては いけません。You must not smoke here.
~ている - ongoing / resultant state
いまあめっています。いま あめが ふっています。It is raining now.

Watch out: ~ている is not always “-ing.” With change-of-state verbs it means a resulting state: 結婚けっこんしています = “I am married,” not “I am in the act of marrying.”

Get every verb group’s te-form to instant, automatic speed. We drill the exact conjugation rules in The Te-Form: N5’s Master Key.

4. The ます-Form and Verb Groups

The ます-form is the polite present/future. Its power comes from the fact that its four inflections (present, negative, past, past-negative) map cleanly across every verb once you know the verb’s group.

FormExample (べる)Meaning
Present/futureべますeat / will eat
Negativeべませんdo not eat
Pastべましたate
Past negativeべませんでしたdid not eat
Common mistake: Guessing the te-form or negative without knowing whether a verb is godan (う-verb) or ichidan (る-verb). かえlooks like an ichidan る-verb but is godan, so its te-form is かえって, not かえて. Learn each verb’s group when you learn the verb.

5. Existence: あります vs います

Japanese uses two different verbs for “there is,” split by whether the thing is alive and self-moving.

あります - non-living
つくえのうえほんがあります。つくえの うえに ほんが あります。There is a book on the desk.
います - living / self-moving
公園こうえんねこがいます。こうえんに ねこが います。There is a cat in the park.

People and animals take います; objects, plants, and buildings take あります. The dividing line is self-directed movement, which is why a taxi you’re riding as a passenger can still take あります.

6. Adjective Conjugation: い vs な

Japanese has two adjective types, and they conjugate differently. This is a second conjugation engine you must run in parallel with verbs.

い-adjective (たかい)な-adjective (しずか)
Presentたかいですしずかです
Negativeたかくないですしずかじゃありません
Pastたかかったですしずかでした
Modifying a nounたかやましずかなまち
Common mistake: Adding な to an い-adjective before a noun - it’s たかやま (a high mountain), never たかな山. Only な-adjectives take な. And beware 綺麗きれい and きらい: they end in い but are な-adjectives.

7. ~たい: Saying What You Want to Do

Verb stem + たい
日本にほんきたいです。にほんへ いきたいです。I want to go to Japan.

~たい conjugates like an い-adjective: negative きたくない, past きたかった. The object particle can be を or が: みずみたい is very natural.

Cultural note: ~たい describes your own desire. Saying 田中さんは行きたいです about a third person is unnatural - for other people you use ~たがっている (wants to). N5 mainly tests first-person ~たい.

8. ましょう / ませんか: Inviting and Suggesting

~ませんか - polite invitation
いっしょにひるごはんをべませんか。いっしょに ひるごはんを たべませんか。Won’t you eat lunch with me?
~ましょう - let’s
じゃ、はじめましょう。じゃ、はじめましょう。Well then, let’s begin.

~ませんか is softer - it invites and leaves room to decline. ~ましょう assumes agreement and proposes doing it together. Native speakers often open with ~ませんか, then confirm with ~ましょう.

How to Turn This List Into Real Ability

Knowing the eight systems is step one. Making them automatic is what passes the exam - and lets you actually speak. Three principles:

Kanjijo was built for exactly this loop - from foundation to fluency:

Deep Dives: Individual Points in Detail

Each of the points below previously lived on its own page. They are collected here so the whole level sits in one place.

N5 〜たい vs 〜が好き: The Desire Grammar Pair Every Beginner Gets Wrong

Both express desire. Both appear in lesson three of every N5 textbook. Both look harmless. And both are responsible for a remarkable number of confused conversations between beginners and native speakers. The traps are not in meaning - they are in particle, person, and politeness.

The 10-second answer: 〜たい uses を or が and only describes your own desire (use 〜たがっている for others). 好き always uses が, never を. Get the person rule and the particle rule, and the pair becomes effortless.

1. The Particle Trap

PatternParticleExample
〜たいを or が寿司を食べたい / 寿司が食べたい
好きが only寿司が好きです
嫌いが only納豆が嫌いです
欲しい (want object)が only新しい携帯が欲しいです

2. The Person Rule (The Big One)

〜たい describes internal desire. Japanese is strict: you cannot claim direct knowledge of someone else’s internal state. So:

  • ✅ 私は日本に行きたいです。
  • ❌ 田中さんは日本に行きたいです。
  • ✅ 田中さんは日本に行きたがっています。

The same rule applies to 欲しい → 欲しがっている and 嬉しい → 嬉しがっている. This is the #1 social register error of N5 learners.

3. The Polite Frame

Tack です on the い-adjective form: 食べたいです / 好きです. For requests, soften with 〜たいんですが (suggesting hesitation): 「すみません、これを試したいんですが…」 - instantly more native.

4. The Negative Forms

  • 食べたい → 食べたくない (don’t want to eat)
  • 好き → 好きじゃない (don’t like)

Note: 〜たい conjugates like an い-adjective; 好き conjugates like a な-adjective. Same English meaning class, completely different Japanese morphology.

5. Why Apps Skip The Hard Parts

Most apps teach 〜たい and 好き in adjacent lessons but never explicitly contrast them. The particle, the person rule, and the negative conjugation difference are left for the learner to absorb by mistake. Kanjijo’s grammar layer treats them as one mini-system, drilling the differences side-by-side.

6. The 5-Sentence Drill

  1. 私はラーメン食べたいです。
  2. 私は犬好きです。
  3. 友達は日本に行きたがっています。
  4. 新しい靴欲しいです。
  5. 納豆好きじゃないです。

If you can produce these five without hesitation, you are ahead of 80% of N5 learners.

Frequently Asked Questions

Either を or が. Both are grammatical; が is more emphatic.

が, always.

Japanese restricts internal-state claims to first person. Use 〜たがっている for others.

もう vs まだ at N5: The Time Pair Every Beginner Trips Over

If a Japanese teacher asked you to translate “not yet”, you would say まだ. Translate “already” and you would say もう. So far so good. The trap appears the moment polarity flips. Both words have two opposite meanings depending on whether the verb is affirmative or negative. That is why beginners - even ones who know the dictionary glosses - slip into まだ食べた (intended “already ate”) which is unnatural in standard Japanese.

The 10-second answer: もう+affirmative = already. もう+negative = no longer. まだ+affirmative = still. まだ+negative = not yet. Four combinations. Memorize the grid, not the words.

1. The Four-Cell Grid

This is the only chart you really need:

Affirmative verbNegative verb
もうalready (the action is done)no longer / not anymore
まだstill (the action is ongoing)not yet (the action has not started)

2. もう + Affirmative - “Already”

This is the version every textbook teaches first. The action is finished or has begun.

もう食べました。 I’ve already eaten.
もう着きました。 I’ve already arrived.
もう8時です。 It’s already 8 o’clock.

3. もう + Negative - “No Longer”

Same word, opposite shape. The action that used to be true is no longer true.

もう飲みません。 I no longer drink.
もう子供じゃない。 I’m not a child anymore.
もう要らない。 I don’t need it anymore.

4. まだ + Affirmative - “Still”

The action or state continues at the moment of speaking.

まだ勉強しています。 I’m still studying.
まだ雨が降っています。 It’s still raining.
まだ時間があります。 There’s still time.

5. まだ + Negative - “Not Yet”

The action has not begun, but is expected to.

まだ食べていません。 I haven’t eaten yet.
まだ来ていません。 They haven’t arrived yet.
まだ準備ができていません。 It’s not ready yet.

6. The Tense Subtlety: ています Beats ました

Here is a refinement most N5 textbooks gloss over. When responding to “Have you eaten?” the most natural Japanese answer for “not yet” uses the negative ていません form, not ませんでした.

Q: もう食べましたか。 Have you eaten yet?
A (yes): はい、もう食べました。
A (no): いいえ、まだ食べていません。 (NOT 食べませんでした)

Why? ませんでした describes a completed non-event in the past (“I did not eat (then)”), but the social meaning of “not yet” is “I have not eaten but I might.” ていません captures that ongoing-not-yet state precisely.

7. Single-Word Replies

もう and まだ work as one-word answers in casual Japanese, and natives lean on them constantly.

  • Q: 終わった? A: もう。 Done already.
  • Q: 食べた? A: まだ。 Not yet.
  • Q: いる? A: もう要らないよ。 I don’t need it anymore.

8. The Top 3 Mistakes Beginners Make

  1. まだ + past affirmative for “already”: ✗ まだ食べた → ✓ もう食べた.
  2. もう + ません when they meant “not yet”: ✗ もう食べません → ✓ まだ食べていません.
  3. もう/まだ confused at restaurants: The waiter says お待たせしました and the customer says まだ when they mean “I’m still deciding” - that one is correct! But many learners answer もう by reflex.

9. The Two-Minute Drill

Pick a single verb, say 食べる. Conjugate it through all four cells aloud:

  • もう食べました。 (already ate)
  • もう食べません。 (no longer eat)
  • まだ食べています。 (still eating)
  • まだ食べていません。 (not yet eaten)

Repeat with three different verbs every morning. By day five your brain has internalized the grid more reliably than any rule explanation could.

Frequently Asked Questions

Already in affirmative sentences, no longer in negative ones.

Still in affirmative sentences, not yet in negative ones.

Each has two opposite meanings depending on verb polarity. Without drilling all four combinations, errors are predictable.

Saying まだ食べた for “already ate.” The correct form is もう食べました.

Use cloze cards that fix the verb polarity and force you to choose between the two adverbs.

How to Master N5 Grammar

  • Learn patterns through example sentences - not abstract rules
  • Review vocabulary with SRS - grammar patterns only stick when you know the words in them
  • Write sample sentences using each pattern to test understanding
  • Kanjijo’s N5 deck covers all 100+ kanji and 800 vocabulary items you need - essential foundation for grammar

Frequently Asked Questions

There are roughly 80–100 grammar patterns tested at N5, but they cluster into about eight core systems: the copula (です/だ), particles, existence verbs (あります/います), the ます-form, the te-form, the ~たい want-form, invitations (ましょう/ませんか), and adjective conjugation. Master those eight and you can decode the vast majority of N5 sentences, because most other patterns are variations built on them.

The te-form (て形). It is the connector that unlocks requests (てください), permission (てもいいです), prohibition (てはいけません), progressive and resultative states (ている), sequences of actions, and dozens of higher-level patterns at N4 and beyond. If you drill one thing to automatic speed at N5, drill te-form conjugation of every verb group.

You need a working rule, not a perfect one. For N5, use は to mark the topic (what the sentence is about) and が to mark the grammatical subject, especially for new information, existence, and question words like 誰 and 何. The distinction gets subtler at higher levels, but the N5 exam rewards the basic topic-vs-subject split, so drill it with real sentences.

Learn each pattern inside a full example sentence, not as an isolated rule, then review those sentences with spaced repetition so recall becomes automatic before the exam. Cloze (fill-in-the-blank) drills are especially effective because the JLPT grammar section is itself a cloze test. Kanjijo pairs a full N5 grammar bank with an SRS engine and example-sentence review so patterns move into long-term memory.
