Yes and no in real Japanese: はい, うん, ええ, いや, ううん

Why you almost never hear いいえ, what people say instead, and how to tell うん ("yeah") from ううん ("nope") when they differ by a single sound.

Ukeru notes · counts are from the current library (1,905 routines, 174,812 machine-transcribed lines) and update as it grows

The word textbooks teach first and you hear least

Every beginner learns the pair on day one: はい for "yes", いいえ for "no". The first half holds up. はい really is everywhere. The second half does not. Listen to real conversation, or to a comedy duo arguing on stage, and いいえ barely turns up. "No" is usually いや, 違う, a short ううん, or no word at all, only a reason why not.

The counts below come from machine-made transcripts of the 1,905 routines in our library, so read them as rough guides rather than exact figures.

はい: yes, and a lot more

Lines starting with はい appear 2,786 times in our library, from 232 of the 283 comedians. Not all of those are answers to a question, though. はい also does other jobs:

• "Here you go": はい、どうぞ (here, take it).
• Getting started: comedy duos often open a routine with はい and a greeting.
• "Got it, I'm listening": はいはい, which can sound impatient if said quickly.
• "Huh?": はい？ with a rising tone means "excuse me?" or "what did you just say?"

So when you hear はい, think "I'm with you" rather than strictly "yes". It is polite enough for anyone: customers, bosses, strangers.

うん: the casual yes

Among friends and family, はい gives way to うん. Lines starting with うん appear 1,242 times, from 181 comedians. The samples show how often it stands alone or doubles up as うんうん, which means "yeah, yeah, go on". Like はい, it signals listening as much as agreement.

うん is for people you speak casually with. Saying it to a teacher or a client can come across as too familiar.

ええ: the soft, grown-up yes

ええ sits between the two: polite, but gentler and a little more conversational than はい. You hear it in interviews and in adult small talk: ええ、そうなんです (yes, that's right). Only 52 lines start with ええ followed by a comma, full stop or exclamation mark, and many of those are not "yes" at all. A drawn-out ええ？ or ええ！ is surprise ("what?!"), so pay attention to the tone. Also remember that in Kansai speech, ええ often means いい ("good"), as in ええやん.

いいえ is real, but rare

いいえ appears on only 29 lines in the whole library, from 23 comedians. Many of those use it the way it is actually used in daily life: to politely wave something away, as in "no, no, please sit down" or "no, not at all". That is its natural home. いいえ、どういたしまして (not at all, you're welcome) is a set phrase. Even there, many speakers prefer the lighter いえいえ.

As a flat "no" to a factual question, いいえ can sound formal, like filling in a form or answering an official. Some people use it, but in casual talk most people reach for something else.

What people say instead of いいえ

いや. This is the big one. Lines starting with いや outnumber lines containing いいえ by about 144 to 1. To be fair, not every いや is a "no". It is also a "well…" or "no, wait" that starts a comeback, and いやー is often just a sigh. Still, the gap is far too wide to explain away. いや、違うよ (no, that's not it) is the everyday shape. See いや and the note いや doesn't just mean no.

違う. Instead of saying "no", people often say "that's wrong": 違う！, 違います, or rougher ちげえよ. It answers the facts rather than the question: 違う、明日だよ (no, it's tomorrow). See 違う／ちげえ, and ちゃう for the Kansai version ちゃう.

Just the reason. Very often nobody says "no" at all. Asked 行く？ (you going?), a speaker might just say ちょっと用事があって (I've kind of got a thing). The listener hears the "no". This is one of the biggest gaps between textbook dialogues and real ones.

うん and ううん: one sound apart

The casual "no" to うん is ううん, and it is easy to miss. The difference is a single extra う, and it works much like English "uh-huh" versus "uh-uh". うん is one smooth syllable. ううん has a break and a change in pitch between the two parts, and it often comes with a small head shake. Don't confuse either with うーん, a long, drawn-out hum that means "hmm, let me think".

In our transcripts, ううん shows up on only a handful of lines (6), and the samples show that even some of those are other words that happen to contain the same letters. It is a quick, quiet word, and a machine transcript can easily miss it or write it as うん. So the count tells you little. For listening, trust the pitch and the context, not the spelling.

A trap: answering negative questions

Japanese yes and no agree or disagree with what was said, not with the underlying fact. Asked 行かないの？ (aren't you going?):

• うん、行かない = "Right, I'm not going."
• ううん、行くよ = "No, I am going."

English speakers often reply the other way round. One catch: a casual question like 寒くない？ often really means "isn't it cold?", and then うん、寒い is a normal "yes, it's cold". When unsure, just say the verb: 行く or 行かない. That is what many native speakers do anyway.

Using them yourself

• はい: safe with anyone. Use it with teachers, at work, in shops and on the phone.
• ええ: polite and soft. It is good with colleagues and people you don't know well. It sounds a bit adult and conversational.
• うん / ううん: friends, family, people your age or younger. Mixing うん into otherwise polite speech with a boss can sound too casual.
• いいえ: correct but stiff as a plain "no". Its best use is politely declining thanks or an offer. いえいえ is lighter.
• いや: common and fine in casual talk. In polite speech, いえ or いや、それは… sounds softer. A sharp いや！ can sound like a refusal or a comeback.
• 違う / 違います: blunt about facts. Soften it at work: ちょっと違うかもしれません (that might not be quite right).

Try it

• Search the library for うん and ううん, then listen to the lines and decide by ear which is which.
• Search for いいえ and note what each one is refusing. How many are polite "no, no, it's fine" moments rather than flat answers?
• Answer out loud, without はい or いいえ: 寒くない？ (aren't you cold?). Try once as "no, I'm fine" and once as "yes, I'm freezing".
