“〜sou desu ne / 〜sou desu yo / 〜sou desu ka”: Aizuchi [JLPT N4]
By Nihongo to Japan · Updated July 3, 2026
Backchanneling expressions for agreement or confirmation.
“〜sou desu ne / 〜sou desu yo / 〜sou desu ka”: Aizuchi
‘Aizuchi (あいづち, backchanneling)' is important in Japanese conversation; 「そうです ＋ ending」 changes function with the ending: ① そうですね = agreement, shared feeling ‘yeah, that's right' (A: 今日は寒いですね B: そうですね = yeah); ② そうですよ = informing the other ‘that's right, you know' (providing info, affirming: そうですよ、明日は休みです); ③ そうですか = learning something new, receiving info ‘I see, oh really' (A: 彼は来ません B: そうですか = I see). ⚠️ Key: the endings ね/よ/か function entirely differently: ね = agreeing/backchanneling, よ = informing, か = learning/receiving! ⚠️ Don't mix them up. Essential backchanneling for daily conversation.
🧠 Core nuance: the ending decides the backchannel's function (agree/inform/receive)
The core is そうです with different endings (ね/よ/か) gives entirely different backchannel functions: Japanese conversation values ‘aizuchi' — responding in a timely way to show you're listening and reacting. ① そうですね — expresses agreement, shared feeling, backchanneling ‘yeah, right, you said it' (echoing the other, agreeing: A: 最近忙しいですね B: そうですね、大変です; also when thinking ‘そうですね…' = well, let me see); ② そうですよ — tells the other ‘that's right, you know,' providing info, affirming, reminding (a more active tone: A: これでいいですか B: そうですよ、大丈夫です); ③ そうですか — learning something new, receiving info ‘I see, oh really' (a response when told news: A: 彼は来ません B: そうですか, falling intonation shows understanding; rising shows some surprise/confirmation). ⚠️ Core: ね = agreement/backchannel (shared knowledge), よ = informing/reminding (I tell you), か = receiving/learning (I just found out) — different directions! ⚠️ Common mistake: mixing them up (✗ saying そうですね on hearing news → should be そうですか). ⚠️ Casually/colloquially you can drop です: そうね/そうよ/そうか (more casual). An N4 daily-conversation backchanneling expression.
📌 The Three Functions
| Expression | Function | Example |
|---|---|---|
| そうですね | agreement, shared feeling (yeah) | A: 寒いね B: そうですね |
| そうですよ | informing the other (that's right, you know) | そうですよ、休みです |
| そうですか | learning/receiving (I see) | A: 来ません B: そうですか |
| (thinking) そうですね… | well… (buffer) | そうですね、考えます |
💬 Example Sentences
- A: 今日は寒いですね。B: そうですね、マフラーが必要ですね。(A: It's cold today. B: Yeah, you need a scarf.) — agreement
- A: 最近忙しそうですね。B: そうですね、少し大変です。(A: You seem busy lately. B: Yeah, it's a bit tough.) — shared feeling
- これは無料そうですよ。(This is free, you know.) — informing
- A: 彼は来ないそうです。B: そうですか、残念ですね。(A: I hear he's not coming. B: I see, that's a shame.) — receiving/learning

🔄 Compare: そうですね vs そうですよ vs そうですか vs そうします
| Expression | Function | Nuance |
|---|---|---|
| そうですね | agreement, backchannel | yeah (shared knowledge) |
| そうですよ | informing the other | that's right, you know (I tell you) |
| そうですか | learning, receiving | I see (I just found out) |
| そうします | I'll do that | a decision/compliance |
⚠️ Common Mistakes
- Don't mix the three: ね = agreement/backchannel, よ = informing, か = learning/receiving; different functions!
- Learning news uses か: when told something new use そうですか (✗ そうですね, that's agreement).
- Informing uses よ: to tell the other info use そうですよ (I tell you).
- そうですね… can buffer: when thinking, ‘そうですね…' = well (buying time).
💡 Nuance & When to Use
「そうです ＋ ending」 is everyday backchanneling, function changing with the ending: そうですね = agreement/shared feeling (yeah), そうですよ = informing the other (that's right, you know), そうですか = learning/receiving (I see). ⚠️ Key: ね = agreement/backchannel, よ = informing, か = receiving new info — don't mix them up! Learning news uses か (✗ ね). Essential backchanneling for daily conversation — master it at N4.
🎯 JLPT Exam Tips
- N4 core: そうですね = agreement/backchannel, そうですよ = informing the other, そうですか = learning/receiving new info; the ending decides the function.
- Most common mistake: learning news uses そうですか (✗ そうですね = agreement).
- Distinction: ね (agreement, shared knowledge) vs よ (informing, I tell you) vs か (receiving, I just found out).
