JLPT N3 has specific grammar and vocabulary traps that English speakers consistently fall into. This guide covers the most common mistakes — and exactly how to avoid them — based on the patterns that appear most frequently on the exam.
| Mistake Category | Common Error |
|---|---|
| Particle choice | Using を instead of に for location/goal |
| Potential form | Confusing できる (general) and 〜られる (specific) |
| Concession | Mixing up のに and ても |
| Causative | Confusing させる (cause) and させられる (be forced) |
| Formality mismatch | Using casual form in formal writing answers |
Mistake 1: Particle Confusion at N3 Level
Yuka
「駅を行く」じゃなくて「駅に行く」！
(It’s not 「駅を行く」, it’s 「駅に行く」!)
Rei
そうだよ！を は通過する場所に使うよ。
(Exactly! を is for places you pass through.)
| Particle | Use | Example |
|---|---|---|
| に | Destination / goal | 駅に行く (go to the station) |
| で | Location of action | 公園で遊ぶ (play at the park) |
| を | Path passed through | 橋を渡る (cross the bridge) |
| が | Subject of potential/emotion | 日本語が話せる (can speak Japanese) |
Mistake 2: Confusing できる and Potential Form
N3 candidates often use できる where the potential form is needed, or vice versa.
| Wrong | Correct | Why |
|---|---|---|
| この本を読めることができる。 | この本が読める / 読むことができる。 | Double-potential — pick one |
| 水泳ができる。(I can swim — specific) | 泳げる。 | できる = ability in general; potential = specific action |
| 彼女は料理ができます。 | OK — 料理 is a noun | できる + noun is correct |
Mistake 3: のに vs ても Confusion
Yuka
「疲れてもいても、仕事をします」は変だよ。
(「疲れてもいても」is strange.)
Rei「疲れていても」が正しいね！
(「疲れていても」is correct!)
| Wrong Context | Correct Pattern | Rule |
|---|---|---|
| Expressing regret about past with ても | Use のに for emotional past contrast | のに = regret/surprise; ても = neutral even if |
| Using のに for future/hypothetical | Use ても for hypotheticals | のに refers to real, past or current facts |
| Mixing くせに with formal writing | Use にもかかわらず in formal contexts | くせに = casual criticism only |
Mistake 4: Causative vs Causative-Passive
This is one of the hardest N3 grammar areas. The causative-passive looks complex but expresses being forced to do something.
| Form | Meaning | Example |
|---|---|---|
| させる | Cause / make someone do | 子供に野菜を食べさせる (make child eat vegetables) |
| させられる | Be made to do (against will) | 野菜を食べさせられた (was made to eat vegetables) |
Yuka
上司に残業させられました…
(I was made to work overtime by my boss…)
Rei
大変だったね。強制された感じが「させられる」に出てるよ。
(That was rough. The feeling of being forced comes through in させられる.)
Mistake 5: Formality Mismatch in Exam Answers
N3 reading and grammar sections sometimes include formal writing. Mixing casual and formal patterns loses marks.
| Situation | Wrong | Correct |
|---|---|---|
| Formal report | 〜と思う | 〜と考えられる / 〜と思われる |
| Formal concession | 〜くせに | 〜にもかかわらず |
| Formal opinion | 〜だと思う | 〜であると思われる |
| Causal in formal text | 〜から | 〜ため / 〜ので |
Study Strategy: Common N3 Traps
Yuka
N3対策のポイントは、「似ている文型の違い」を覚えることだよ。
(The key to N3 prep is memorizing the differences between similar grammar patterns.)
Reiそれぞれの「ニュアンスの差」が試験に出るよね。
(The nuance differences between them are what the exam tests.)
| Pair | How to Distinguish |
|---|---|
| のに vs ても | のに = regret about real event; ても = hypothetical/neutral |
| ために vs ように | ために = intentional action goal; ように = state/ability goal |
| ほど vs くらい | ほど = extent comparison; くらい = approximate degree |
| させる vs させられる | させる = you force; させられる = you are forced |
Quick Quiz: Spot the Mistake
1. 日本語を勉強したても、難しい。 → _____
→ 勉強しても (て-form: 勉強して + も)
2. 雨のため行きますでした。 → _____
→ 雨のため、行きませんでした (negative + でした for past)
3. 彼は何もしないのに、できる振りをする。 → _____
→ くせに (criticism nuance is better matched by くせに here)
