JLPT N5 Grammar: 15 Essential Patterns Every Beginner Must Know

You’ve decided to take the JLPT N5 — or you’ve just started learning Japanese and want a solid foundation. Either way, you’ve come to the right place. The N5 is the entry point for Japan Language Proficiency Test certification, and mastering these 15 grammar patterns doesn’t just help you pass the exam: it gives you the structural backbone for everything that follows at N4, N3, and beyond.

These patterns appear in nearly every Japanese sentence. Once they become second nature, you’ll be able to read basic signs, hold simple conversations, and understand the logic behind Japanese sentence structure. Let’s work through all 15 together.

1. Basic Sentence Structures: The は・です Backbone

Three patterns form the absolute core of written and spoken Japanese at N5. Every other pattern builds on top of them.

Pattern 1: 〜は〜です (A is B)

Formula: [Topic] は [Noun / Adjective] です

は (wa) marks the topic of the sentence — the thing you’re talking about. です (desu) is the polite copula, equivalent to “is / am / are.”

Pattern 2: 〜は〜ではありません (A is not B)

Formula: [Topic] は [Noun] ではありません

ではありません (de wa arimasen) is the negative form of です. In casual speech you will often hear じゃないです (ja nai desu), but for N5 and formal use, learn ではありません first.

Pattern 3: 〜は〜ですか (Is A B?)

Formula: [Topic] は [Noun / Adjective] ですか

Japanese forms yes/no questions simply by adding か (ka) to the end of a statement. No need to rearrange word order the way English does.

Yuka

これはときどけですか。 Kore wa tokidoke desu ka? — Is this a watch? It’s literally just 「this topic-marker watch is question-marker」 — that simple sentence structure takes you so far at N5.

Rei

はい、そうです。 Hai, sou desu. — Yes, that’s right. And いいえ、そうではありません (iie, sou de wa arimasen) for “No, that’s not right.” Those two responses handle almost any ですか question.

2. Particles: The Workhorses of N5

Japanese particles are small words attached after nouns that tell you the grammatical role of that noun in the sentence. Think of them as labels: “this noun is the subject,” “this noun is where the action happened,” and so on. N5 tests eight key particles.

が (ga) — Subject Marker

Key use case: Marks what does or exists. Contrasts with は by putting new information or focus on the subject.

を (wo/o) — Object Marker

Key use case: Marks the direct object — the thing that receives the action of a transitive verb.

に (ni) — Location, Direction, Time

Key use case: Three core functions at N5: (1) destination of movement, (2) location of existence, (3) specific time.

で (de) — Place of Action / Means

Key use case: Marks where an action takes place (not where something exists) or by what means an action is done.

へ (e) — Direction

Key use case: Indicates direction of movement. Often interchangeable with に for destinations, but へ emphasizes the direction rather than the arrival point.

と (to) — And / With

Key use case: Connects two nouns (“A and B”) or marks the person you do something together with.

も (mo) — Also / Too

Key use case: Replaces は or が to add “also / too” to a noun. It signals inclusion of an additional item or person.

から / まで (kara / made) — from / Until

Key use case: から marks a starting point (time or place); まで marks an end point. They are often used together.

3. Verb Conjugation Basics: The Masu-Form System

At N5, Japanese verbs in polite speech all follow the 〜ます (masu) system. This one pattern covers present/future affirmative, present/future negative, past affirmative, and past negative — four forms every beginner must know.

Why this matters: The masu-form is polite speech — the default register for any situation where you’re not speaking to a close friend. It’s also the form tested most heavily on the N5 reading and listening sections.

Verb groups at N5: Japanese verbs fall into three groups (u-verbs, ru-verbs, and irregulars), but at N5 you mainly need to recognize the masu-form endings, not produce all conjugations from scratch. The two common irregular verbs — する (suru, “to do”) → します and くる (kuru, “to come”) → きます — appear on the exam and should be memorized directly.

4. Adjective Patterns

Japanese has two types of adjectives, and N5 tests both: い-adjectives (i-adjectives) and な-adjectives (na-adjectives). The difference matters because they conjugate differently.

い-Adjectives

い-adjectives end in い and conjugate by changing or dropping that final い.

な-Adjectives

な-adjectives behave more like nouns. They use です, ではありません, でした, and ではありませんでした for their four forms.

5. Connecting Ideas

Once you can build individual sentences, N5 introduces three ways to link them together.

〜て-form for Sequence (“and then”)

Formula: [Verb て-form], [next action]

The て-form connects two actions in sequence. It signals that the first action happens, and then the second one follows.

〜から (kara) — Because

Formula: [Reason sentence] から、[result sentence]

から placed after a clause gives the reason. It is the most common “because” at N5.

〜が (ga) — But / However (Contrast)

Formula: [Statement A] が、[Statement B]

When が appears between two complete clauses (rather than marking a subject), it introduces a contrast — similar to “but” or “however.” This is a separate use from the subject-marking が.

Yuka

にほんごはおもしろいですが、かんじがたくさんあるから、がんばりますよ。 Japanese is interesting, but there are a lot of kanji, so I’ll keep working hard!

Rei

そうですね。 That sentence used THREE patterns from this article — は + です, が for contrast, and から for reason. Once these patterns click, they naturally combine.

6. Expressing Ability and Desire

〜ことができます (koto ga dekimasu) — Can / Able to

Formula: [Verb dictionary form] + ことができます

This pattern expresses ability or possibility. It attaches to the plain (dictionary) form of a verb and adds こと (koto, “the act of”) + ができます (“can do”).

〜たいです (tai desu) — I Want to

Formula: [Verb stem (ます-stem)] + たいです

たい (tai) attaches to the verb stem and expresses personal desire. It only describes the speaker’s own wishes — at N5 you should not use it to say what others want (that requires たがっています at N4).

7. Common Mistakes at N5 Level

Even learners who understand the grammar above often trip over three recurring mistakes. Knowing them in advance will save you marks on the exam.

Mistake 1: Using は Instead of が (and vice versa)

At N5 the most important distinction is: use が when introducing new information or when answering a “who/what” question; use は when you are talking about an established topic.

Mistake 2: Using を with Movement Verbs (Should Be に or へ)

Many English learners try to mark the destination of “go” or “come” with を because English says “go TO school” and they think of を as marking the thing the verb acts on. But movement verbs like いく / くる / かえる use に or へ for the destination, not を.

Exception: を is used with verbs of passing through or leaving: こうえんをさんぽします (I walk through the park), えきをでます (I exit the station). These are N5 edge cases — just be aware they exist.

Mistake 3: Forgetting the Particle After Time Words

In English you say “on Monday,” “in April,” “at 3 o’clock” — the preposition comes before the time word. In Japanese, に comes after the time word. Learners often drop it entirely.

Note: Some time expressions do NOT use に — words like きょう (today), あした (tomorrow), まいにち (every day), and らいしゅう (next week) stand alone without a particle. This is a common N5 trap question.

Yuka

まいにち&#x306B — wait, no particle needed! まいにち (every day) never takes に. But 月曜日に (on Monday) does. The rule: specific, named time points take に; relative or habitual time words don’t.

Rei

That’s the kind of detail the N5 exam loves to test. A sentence like 「あしたにいきます」 looks correct to beginners but あした is a relative time word — no に needed: あしたいきます.

Quick Quiz

Test yourself on these five N5 patterns. Fill in the blank with the correct particle or verb form.

1. わたし___がくせいです。
Answer: は — は marks the topic (the speaker introducing themselves)

2. まいにち___じゅうじにねます。
Answer: No particle before まいにち; the blank before じゅうじに should be filled with に — Full sentence: まいにちじゅうじにねます。 (I go to sleep at 10 every night.) Note: まいにち takes no particle; じゅうじ takes に.

3. にほんご___はなすことができます。(I can speak Japanese.)
Answer: を — にほんごをはなすことができます。 The verb はなす (to speak) is transitive; にほんご is the object, marked by を.

4. きのうえいが___みました。 (I watched a movie yesterday.)
Answer: を — えいがをみました。 The direct object (movie) is marked by を.

5. このケーキはおいし___。 (This cake was delicious.) — Use the past form of おいしい.
Answer: おいしかったです — い-adjective past affirmative: drop い, add かったです.
