How do you answer a negative question in Japanese?

You agree or disagree with the sentence, not with the fact - which reverses the English pattern. Asked 行かないんですか (aren't you going?), a person who is not going says はい、行きません, meaning that's right, I'm not going. A person who is going says いいえ、行きます, meaning that's wrong, I am going. English does the opposite: no, I'm not and yes, I am. Because this reversal is easy to get wrong under pressure, the safest beginner strategy is to skip はい and いいえ entirely and simply repeat the verb: 行きます or 行きません. That answer is unambiguous in both languages and is what many native speakers do anyway.

Does はい mean yes in Japanese?

Only sometimes. Its core meaning is closer to I have received what you said. It works as yes when the question is positive, but it is also the standard listening signal - the あいづち that a listener produces every few seconds to show attention, which is why a phone call can contain はい、はい、はい with no agreement involved. It is also what you say when handing something over (はい、どうぞ) and when answering a roll call. Treating はい as a commitment to yes is what leads beginners to agree to things they did not intend.

Why do Japanese people rarely say いいえ?

Because a bare いいえ contradicts the other person directly, which in ordinary conversation feels blunt rather than merely negative. It survives on forms, in classrooms and in formal question-answer exchanges, but in daily speech people reach for softer or more specific alternatives: ううん in casual speech, いや or いやいや among friends, 違います to correct a factual error, そうじゃないです to deny a characterisation, ちょっと to decline an invitation without stating a refusal, and 大丈夫です to turn something down politely. Choosing among these is not about politeness level alone - each one denies a different thing.

Does 大丈夫です mean yes or no?

Both, and context decides. Its literal sense is I'm fine, there's no problem. When someone asks whether you are hurt or whether a time suits you, it means yes, fine. When someone offers you something - a bag, a receipt, more rice, help with your luggage - it means no thank you, I'm fine without it. At a convenience store, 袋は大丈夫ですか followed by 大丈夫です is the single most common place learners accidentally decline or accept the wrong thing. The fix is to never use it alone in an offer situation: say はい、お願いします to accept and いえ、大丈夫です to decline. 結構です behaves the same way but carries more risk, because in some tones it reads as haughty.

What is the difference between いいです and いいですよ?

Grammatically almost nothing; in practice they often point in opposite directions. いいですよ with a warm, slightly rising delivery grants permission or accepts an offer - sure, go ahead. A flat いいです, especially with a small raised hand or a slight head shake, declines - I'm fine, no need. The particle よ pushes the statement towards the listener as something offered to them, which is why it tends to land as acceptance, while the bare form more often reads as self-contained refusal. Since neither reading is guaranteed, add the verb when it matters: いいですよ、どうぞ to accept and いえ、大丈夫です to decline.

はい Doesn't Always Mean Yes: How Japanese Answers Questions (N5)

The short version: はい means “what you said is correct”, not “yes”. So when the question is negative — 行いかないんですか, aren't you going? — someone who is not going answers はい、行きません, the exact reverse of English. The beginner-proof fix: skip はい and いいえ and repeat the verb.

Level: N5–N4. All vocabulary here is beginner level with furigana throughout. Nothing on this page is advanced — it is simply a piece of the language that textbooks present as a one-line vocabulary item (はい = yes) and then never revisit.

The moment usually looks like this. You are at a convenience store. The clerk asks something short with 大丈夫 in it. You say はい because はい is safe. And then you are handed a bag you did not want, or not handed the one you did, and you walk out unsure which of those just happened.

It was not a vocabulary failure. はい and いいえ are not translations of yes and no. They belong to a different system, and the difference is precise enough to state in one sentence.

English answers the fact. Japanese answers the sentence.

When an English speaker says yes, they are asserting that the thing is true. When a Japanese speaker says はい, they are asserting that the sentence you just produced is correct. With a positive question these two never come apart:

Positive question — English and Japanese agree

They ask

行いきますか。いきますか。Are you going?

You are going

はい、行いきます。はい、いきます。Yes, I'm going.

You are not going

いいえ、行いきません。いいえ、いきません。No, I'm not going.

Now make the question negative, and the two systems come apart completely.

Negative question — the flip

They ask

行いかないんですか。いかないんですか。Aren't you going? / You're not going?

You are NOT going

はい、行いきません。

はい、いきません。
“That's right — I'm not going.”
English would say No, I'm not.

You ARE going

いいえ、行いきます。

いいえ、いきます。
“That's wrong — I am going.”
English would say Yes, I am.

Read the logic once and it stops being strange. The speaker proposed a statement: you are not going. はい confirms that proposal; いいえ rejects it. Japanese is being perfectly consistent — it is English that changes what yes refers to depending on the question.

The strategy that never fails: drop yes and no, and repeat the verb. 行いきます。 or 行いきません。 on its own is a complete, natural, unambiguous answer in Japanese, and it cannot be misread in either language. Native speakers do this constantly precisely because negative questions are slippery for them too. Use it whenever the question contains ない, and you will never make this mistake again.

Most of the time, はい is not an answer at all

Here is the second thing nobody mentions. In a normal Japanese conversation, the majority of はい you hear are not answering anything. They are 相あい槌づち — listening signals, produced every few seconds to show the speaker you are still with them. Silence while someone talks reads as absence or displeasure in Japanese, so the listener keeps a steady rhythm of はい, ええ, そうですね, なるほど.

That is why a phone call can run はい…はい…はい…はい, with the person agreeing to nothing whatsoever. It is also the origin of a very common misunderstanding in the other direction: visitors conclude that Japanese colleagues “agreed” in a meeting, when every はい in the room meant I am following you. The full system is in the aizuchi guide.

はい does three further jobs that have nothing to do with yes:

Situation	What is said	What it means
Handing something over	はい、どうぞ。	Here you are.
Answering your name being called	はい。	Present. / That's me.
Moving a group along	はい、次つぎ。	Right — next.
Listening on the phone	はい…はい…	I'm still here, go on.

What Japanese speakers say instead of いいえ

Textbook Japanese pairs はい with いいえ and leaves it there. In real speech, a bare いいえ is genuinely uncommon — it contradicts the other person head-on, which registers as blunt rather than merely negative. It lives on forms, in classrooms, and in formal question-and-answer, and elsewhere people reach for something that denies a specific thing:

Instead of いいえ	Register	What it actually denies
ううん	casual	Plain no, to friends and family. The everyday spoken equivalent of いいえ.
いや / いやいや	casual	No, often with a mild “come on” flavour. いやいや also deflects a compliment.
違ちがいます	polite	A factual error. Use when someone has the wrong information — wrong name, wrong floor, wrong assumption.
そうじゃないです	polite	A characterisation. Softer than 違います — “it's not quite like that.”
ちょっと…	polite	An invitation or request. Never finish the sentence — the trailing off is the refusal.
大丈夫だいじょうぶです	polite	An offer. “I'm fine without it.” See the warning below.
結構けっこうです	risky	An offer, formally. Correct but easy to deliver in a way that sounds haughty. Prefer 大丈夫です.

Notice that these are not simply politeness levels of one word. 違ちがいます corrects a fact; そうじゃないです adjusts an impression; ちょっと declines a request. Swapping them changes what you are denying. The speaker-side system for turning things down is covered in how to say no in Japanese.

The three phrases that mean both yes and no

大丈夫です is the one that catches everybody. Its literal sense is I'm fine, there's no problem — which points one way when someone asks about your condition and the opposite way when someone offers you something.

Asked about your state → YES

大丈夫だいじょうぶですか。

Are you all right?
— 大丈夫だいじょうぶです。 = Yes, I'm fine.

Offered something → NO

袋ふくろは大丈夫だいじょうぶですか。

Do you need a bag?
— 大丈夫だいじょうぶです。 = No thanks.

The convenience-store fix — memorise these two lines

To accept

はい、お願ねがいします。はい、おねがいします。Yes, please.

To decline

いえ、大丈夫だいじょうぶです。いえ、だいじょうぶです。No, I'm fine, thank you.

Never use 大丈夫です alone when something is being offered. Pair it with いえ to decline, or replace it entirely with お願いします to accept. Two fixed lines cover every bag, receipt, chopsticks, warming-up and point-card question you will ever be asked — the whole shop script is in what the konbini clerk just said.

いいですよ → usually YES

いいですよ。

Warm, slightly rising. Sure, go ahead / that's fine by me.

いいです → often NO

いいです。

Flat, sometimes with a small raised hand. I'm fine — no need.

The particle よ pushes a statement outward, towards the listener, as something being given to them — which is why it tilts towards acceptance. The bare form stays with the speaker and tilts towards refusal. Neither reading is guaranteed, so when it matters, add the verb: いいですよ、どうぞ to accept, いえ、大丈夫だいじょうぶです to decline.

Answering “is it X?” without saying yes

One more trap, and it is a grammar one. そうです means that's right — but only for questions about nouns and な-adjectives. For verb questions it is simply wrong, and the mistake is extremely common:

Correct — noun question

学生がくせいですか。 — はい、そうです。

Are you a student? — Yes, I am.

Wrong — verb question

食たべますか。 — ~~はい、そうです。~~

Say はい、食たべます。 instead.

And when you genuinely do not know, Japanese gives you comfortable ways to say so rather than guessing: たぶん (probably), どうでしょう (I wonder / hard to say), ちょっと分わかりません (I'm not quite sure). All three are more natural than a committed はい you are not sure about.

Try it — six questions

今日きょうは働はたらかないんですか。
You're not working today? — you are not working.
Show answer
はい、働はたらきません。 — or simply 働はたらきません。 English would say “no”; Japanese confirms the sentence.
コーヒー、飲のまないんですか。
You don't drink coffee? — you do.
Show answer
いいえ、飲のみます。 The いいえ rejects their statement, not the coffee.
袋ふくろ、ご利用りようですか。
Would you like a bag? — you would.
Show answer
はい、お願ねがいします。 Do not answer 大丈夫です here — it would decline.
お箸はしはご利用りようですか。
Do you need chopsticks? — you don't.
Show answer
いえ、大丈夫だいじょうぶです。 The いえ makes the refusal unmistakable.
田中たなかさんですか。
Are you Mr/Ms Tanaka? — you are not.
Show answer
いいえ、違ちがいます。 A factual error, so 違います rather than そうじゃないです.
写真しゃしんを撮とってもいいですか。
May I take a photo? — you want to allow it.
Show answer
いいですよ、どうぞ。 The よ plus どうぞ removes any chance of it reading as a refusal.

One honest caveat. Younger speakers sometimes answer negative questions “English-style”, and in fast conversation even native speakers occasionally have to check what the other person meant. This is not a rule you can lean on with total confidence in either direction — which is exactly why the verb-repeating strategy above is worth making automatic. It is not a beginner's crutch; it is what fluent speakers fall back on too.

Quick reference

What はい actually means: “What you said is correct” — and very often just “I'm listening” (相槌).
Negative question, you agree with it: はい + negative verb. 行かないんですか → はい、行きません.
Negative question, you disagree: いいえ + positive verb. 行かないんですか → いいえ、行きます.
Safest answer at any level: Drop yes/no, repeat the verb: 行きます / 行きません.
Instead of いいえ: ううん (casual) · いや (casual) · 違います (wrong fact) · そうじゃないです (wrong impression) · ちょっと… (declining) · 大丈夫です (declining an offer).
大丈夫です: Asked about your state = yes, fine. Offered something = no thanks. Always pair it: はい、お願いします to accept, いえ、大丈夫です to decline.
いいです vs いいですよ: いいですよ (warm, rising) usually accepts; flat いいです usually declines.
そうです: Only answers noun and な-adjective questions. For verbs, repeat the verb.
When you don't know: たぶん · どうでしょう · ちょっと分かりません.

Frequently Asked Questions

You agree or disagree with the sentence, which reverses English. 行かないんですか — if you are not going, はい、行きません; if you are going, いいえ、行きます. Because the reversal is easy to fumble under pressure, the safe move is to drop yes/no and just repeat the verb: 行きます or 行きません.

Only sometimes. Its core sense is “I have received what you said”. It is also the standard listening signal (相槌), which is why a phone call can be はい、はい、はい with nothing agreed, and it doubles as “here you are” (はい、どうぞ) and as “present” in a roll call.

Because a bare いいえ contradicts the speaker head-on and reads as blunt. Daily speech uses ううん and いや casually, 違います for a wrong fact, そうじゃないです for a wrong impression, ちょっと… to decline an invitation and 大丈夫です to turn down an offer. Each denies a different thing, so they are not interchangeable.

Both. Asked whether you are all right, it means yes, I'm fine. Offered a bag, a receipt or help, it means no thank you. The convenience-store bag question is where beginners most often get it backwards. Use はい、お願いします to accept and いえ、大丈夫です to decline, and never say 大丈夫です alone in an offer situation.

いいですよ, warm and slightly rising, usually grants or accepts — sure, go ahead. A flat いいです, often with a small raised hand, usually declines — I'm fine, no need. Neither is guaranteed, so add the verb when it matters: いいですよ、どうぞ or いえ、大丈夫です.
