The Particle “wa”: Topic, Contrast, Emphasis [JLPT N5]
By Nihongo to Japan · Updated July 3, 2026
「私は学生です」vs「私が学生です」 — one particle's difference, worlds apart in meaning.
The Particle “wa”: Topic, Contrast, Emphasis
The particle 「は」 (read wa) marks a sentence's ‘topic' (as for …), with three main uses: ① topic “as for 〜, regarding 〜”: 「私は学生です」 (I'm a student ← as for me), 「これは何ですか」 (what is this); ② contrast (implying a comparison): 「コーヒーは好きですが、お茶は…」 (I like coffee, but tea…), 「猫は好き、犬は嫌い」; ③ emphasis (negation, limitation): 「あまり高くはない」 (not so expensive), 「行きはしない」. ⚠️ Most important contrast with 「が」: 「は」 = topic/known, focus is after (私は学生 = I ‘am a student'); 「が」 = protagonist/new info, focus is before (私が学生 = ‘I' am the student)! ⚠️ A question word as subject uses が (誰が), the answer uses が (私が); は can't be used for a question-word subject.
🧠 Core nuance: presenting a ‘topic,' focus lands after
The core is は presents a sentence's topic (as for …), with the focus on the following predicate: ① topic ‘as for 〜, regarding 〜' — making something the subject of discussion, followed by a statement about it (私は学生です = as for me, I'm a student, 象は鼻が長い = as for elephants, the nose is long, 今日は寒い = today (the topic) is cold); ② contrast — は often implies ‘a comparison with something else' (コーヒーは好きですが、お茶は好きじゃない = I like coffee but not tea, 猫は好き、犬は嫌い, 私は行くが彼は行かない, two は forming a contrast); ③ emphasis (often in negation, limitation) — strengthening the tone, often partial negation (あまり高くはない = not so expensive, そう簡単にはいかない = not that simple, 食べはした = I did eat). ⚠️ Core contrast with 「が」 (most important): 「は」 = topic/known info, focus on ‘the following predicate' (私は学生です = I ‘am a student,' answering ‘what are you'); 「が」 = protagonist/new info, focus on ‘the preceding subject' (私が学生です = ‘I' am the student, answering ‘who is the student')! ⚠️ Important rule: a question word as subject uses が (誰が来た?, ✗ 誰は); the answer also uses が (私が). But a question word as predicate (asking content) uses は (これは何ですか). ⚠️ は replaces が/を (✗ 私がは→私は), added after に/で etc. (ここには). The most important N5 particle.
📌 Three Uses
| Use | Nuance | Example |
|---|---|---|
| topic | as for 〜, regarding 〜 | 私は学生です |
| contrast | implying a comparison | コーヒーは好き、お茶は… |
| emphasis (negation/limit) | strengthening (often partial negation) | あまり高くはない |
💬 Example Sentences
- これは何ですか?(What is this? ← asking content, topic uses は) — topic
- コーヒーは好きですが、お茶はあまり…。(I like coffee, but tea not so much.) — contrast
- 猫は好きですが、犬は嫌いです。(I like cats but dislike dogs.) — contrast
- 「誰が発表しますか?」「私が発表します。」(Who presents? ‘I' will. ← answer uses が, not は) — contrast with が
- 料理はおいしかったですが、サービスはよくなかった。(The food was good, but the service wasn't.) — contrast
🔄 Compare: は vs が (the most important contrast)
| Item | は | が |
|---|---|---|
| marks | topic/known | protagonist/new info |
| focus | after (predicate) | before (subject) |
| question word as subject | ✗ (can't) | must use が (誰が) |
| answering (who) | — | 私が |
| implies | often contrast | exclusive, specific |
⚠️ Common Mistakes
- は vs が, reversed focus: 私は学生 (I ‘am a student'); 私が学生 (‘I' am the student); different focus!
- A question-word subject doesn't use は: 誰が来た? (✗ 誰は); the answer uses が (私が), not は.
- は for contrast: コーヒーは好き、お茶は… (two は forming a contrast); negation often uses は (あまり〜はない).
- は replaces が/を: ✗ 私がは→私は; with に/で added after (ここには, これでは).
💡 Nuance & When to Use
The particle 「は」 (read wa) presents a sentence's topic (as for …), with three uses: topic (私は学生です), contrast (コーヒーは好き、お茶は…), emphasis/partial negation (あまり高くはない). ⚠️ Most important contrast with が: は = topic/known (focus after: I ‘am a student'), が = protagonist/new info (focus before: ‘I' am the student); a question-word subject uses が, the answer uses が. The most important N5 particle — memorize it.
🎯 JLPT Exam Tips
- N5 core: は = topic (私は学生です), contrast (コーヒーは好き、お茶は…), emphasis/partial negation (あまり〜はない).
- Most important contrast: は (topic/known, focus after) vs が (protagonist/new info, focus before) — 私は学生 vs 私が学生.
- Rule: a question word as subject uses が (誰が), the answer uses が (私が); asking content uses は (これは何).
