What's wrong in Japanese: どうしたの (doushita no), and why 何なにが悪わるい sounds angry

To say "What's wrong?" in Japanese, use どうしたの? (doushita no) with friends and どうしたんですか? (doushita n desu ka) in polite speech. Do not translate it word for word as 何なにが悪わるい? — that means "So what's wrong with it?!" and sounds like the start of a fight.

English uses one short phrase for a whole range of situations: a friend looks down, a stranger has dropped something, a child is crying, a machine has stopped. Japanese splits that range across several phrases, and picking the wrong one is how a caring question turns into an accusation. This article sorts them by situation.

The basics

What is the everyday way to say "What's wrong?" in Japanese?

どうしたの? (doushita no) is the default. Use it when someone looks upset, tired or off, and you are on casual terms with them.

どうしたの? — What's wrong? / What happened? (casual, the all-purpose caring question) どうしたの、元気げんきないね。 — What's wrong? You don't seem like yourself. (casual, noticing a mood)

Literally it is "what did you do / how did it go?", from どう (how) + した (did). English speakers read it as "what's wrong", but Japanese does not say "wrong" at all. It simply asks "how did things turn out this way?", which is why it works for good surprises too: どうしたの、その髪かみ! can mean "What happened to your hair?!" in either direction.

What does the の at the end do?

The の turns a bare question into a request for an explanation, and it softens the tone. 「どうした?」 alone is clipped. 「どうしたの?」 sounds like you are leaning in and inviting them to talk. This is the same explanatory の that appears in 〜んですか. If that grammar is new, read the explanatory のです / んです first, because it explains why どうしたんですか is the polite version of どうしたの.

How do you say it politely?

どうしたんですか? (doushita n desu ka) is the polite form. Use it with a customer, a coworker you don't know well, a teacher or anyone older.

どうしたんですか。顔色かおいろが悪わるいですよ。 — What's wrong? You look pale. (polite, noticing someone looks unwell) お客様きゃくさま、どうなさいましたか。 — Sir/Madam, what seems to be the matter? (very formal, shop and hotel staff)

どうしましたか is also correct and slightly more neutral, the kind of thing a doctor or clerk says. The んです version sounds warmer because it shows you noticed something and care about the reason.

Beyond the basics

What about plain どうした?

どうした? with no の is the blunt, short version. It is common in male speech, between close friends and in anime, where it often sounds cool, protective or impatient depending on the tone.

どうした? — What's up? / What's wrong? (very casual, short, often masculine) おい、どうした。しっかりしろ。 — Hey, what's wrong? Pull yourself together. (rough, commanding, typical hero or senior character)

A character who runs up to a friend and says just どうした? is usually showing that they are worried and want the point fast. Added の makes it gentler, so a calm older-sister type will say どうしたの? while a rugged captain says どうした?. Neither is wrong; they just draw different characters.

How do you ask "Did something happen?"

何なにかあった? (nanika atta) asks whether something happened. Use it when you sense a mood change but do not know the cause, and want to give the person room to say "yes" or "no".

何なにかあった? — Did something happen? (casual, gentle opening) 何なにかあったんですか。 — Did something happen? (polite)

Compare it with どうしたの. どうしたの assumes something is wrong and asks for it. 何なにかあった? is a softer, more open check, which is why it appears in drama scenes where one character senses something is off. For a wider tour of question words like 何なに and どこ, see the question words nani, doko and itsu.

What if you already know something happened?

何なにがあったの? (nani ga atta no) asks "What happened?" and expects a story. You use it after the fact: a friend comes home upset, a child is injured, someone shows up late and out of breath.

何なにがあったの? ちゃんと話はなして。 — What happened? Tell me properly. (casual, serious, asking for the full story) 何なにがあったんですか。 — What happened? (polite, event-focused)

Note the が here. 何なにが marks the unknown subject ("what happened"), so it is a real question about an event. Hold on to that が, because the next section depends on it.

Is 大丈夫だいじょうぶ? the same as "What's wrong?"

Not quite, but it covers the same moment. 大丈夫だいじょうぶ? (daijoubu) means "Are you OK?" and is what people say when they see someone stumble, cough or look pale.

大丈夫だいじょうぶ? — Are you OK? (casual, immediate concern) 大丈夫だいじょうぶですか。 — Are you all right? (polite, to a stranger who fell)

The natural answers are 大丈夫だいじょうぶ (I'm fine), 大丈夫だいじょうぶじゃない (I'm not fine, said when you finally admit it) and 何なんでもない (it's nothing). There is a twist: 大丈夫だいじょうぶ can also mean "no thanks", not only "I'm fine". That is covered in the meaning of 大丈夫だいじょうぶ.

How do you ask about pain or illness?

When the "wrong" is physical, Japanese goes straight to the body.

どこか痛いたい? — Does something hurt? (casual, to a child or friend) 具合ぐあいが悪わるいんですか。 — Are you not feeling well? (polite) 気分きぶんが悪わるいの? — Do you feel sick? (casual, to someone pale or dizzy)

具合ぐあいが悪わるい literally uses 悪わるい ("bad"), and that is fine here because 悪わるい is describing condition — not blaming anyone. That is a useful contrast with the trap in the next section.

What about moods and machines?

For a person's mood, the pattern is 〜悪わるい? with a state word:

調子悪ちょうしわるい? — Not feeling well? / Off your game? (casual, health or performance) 機嫌きげん悪わるい? — Are you in a bad mood? (casual, to someone who seems irritated; be careful, this can provoke)

For a thing that is broken, ask where the problem is with どこが悪わるいの?

どこが悪わるいの? 音おとが出でないんだけど。 — What's wrong with it? There's no sound. (casual, a device or part)

The same phrase at a clinic, どこが悪わるいんですか, asks "Where is the problem?" about the body. Here どこ (where) points at the location of the fault, and 悪わるい describes a condition. That is a different job from the next phrase.

Common mistakes

Why does 何なにが悪わるい sound like a fight?

This is the big trap. English "What's wrong?" looks like 何なにが悪わるい?, but in Japanese 何なにが悪わるいの? almost always means "And what's wrong with that?", a defensive reply, not a caring question.

何なにが悪わるいの? — So what's wrong with that? (casual, defensive, a pushback) 何なにが悪わるいんですか。 — What exactly is wrong with it? (polite on the surface, very cold in tone)

The difference is whose side the speaker is on. どうしたの? is about the person: "You seem off, I'm here." 何なにが悪わるい? is about blame: "Which part of what I did is the fault?" If you meet a friend who looks sad and say 何なにが悪わるいの?, you will sound like you are objecting to their sadness. The nearest caring cousin is どこが悪わるいの (which part of the body or thing is the problem), as shown above.

If your first instinct is to use 悪わるい, stop and ask whether you mean condition (具合ぐあいが悪わるい, fine) or fault (何なにが悪わるい, fight). If you want more on how anger shows up in Japanese, angry in Japanese: 怒おこる and むかつく covers the vocabulary these phrases often lead into.

Why is どうしたの not the same as どうするの?

Learners often hear both phrases and merge them. They differ by one letter and one tense, but they point in opposite directions.

どうしたの? — What happened? / What's wrong? (past form, about something already true) どうするの? — What are you going to do? (non-past, about a decision still to come)

した is the past tense, so you are asking about a situation that has already occurred. する is the non-past, so you are asking for a plan. Saying どうするの to a crying friend is like saying "So what are you going to do about it?", which sounds cold. Saying どうしたの to someone who has not decided where to eat leaves them confused about what has happened.

Why do people answer 何なんでもない or 別べつに?

When someone is not ready to talk, the standard shield is 何なんでもない ("It's nothing") or the shorter 別べつに ("Not really"). In anime these are often cues that the character is hiding something, and the other person usually presses on with 本当ほんとうに? ("Really?").

何なんでもない。 — It's nothing. (casual, a deflection, tone decides if it is true) 別べつに。 — Nothing in particular. (very casual, can sound cold or sulky) ちょっとね… — Well, a little... (casual, trailing off, an invitation to ask more)

ちょっとね… is the one that actually opens the door: it admits that something is wrong without having to say it. A good listener hears it and stays.

Other slips

  • Using 大丈夫だいじょうぶ? as the only question. It is fine for a quick check, but it invites 大丈夫だいじょうぶ as an automatic answer. If you want the real story, follow with どうしたの or 何なにがあったの.
  • Saying どうしたんですか to a stranger at the wrong moment. It is polite, but it still presses for a reason. At a shop counter, お困こまりですか ("Are you having trouble?") is smoother.
  • Adding は. どうしたは? is not a sentence. The structure is どうした + の (or んですか), never は.

The quick comparison

何なにかあった? Mood feels off, cause unknown Casual Gentle probe 何なにかあった?
大丈夫だいじょうぶ? Someone stumbles or looks pale Casual Immediate concern 大丈夫だいじょうぶ?
何なにがあったの? You know something happened Casual Fact-finding, wants the story 何なにがあったの? ちゃんと話はなして。
どこか痛いたい? Pain or illness Casual Physical check どこか痛いたい?
何なにが悪わるいの? Someone criticises you Casual Defensive, challenging 何なにが悪わるいの?

Practice

Build each answer before opening it. Questions 3 and 4 are a pair, and so are 5 and 6.

1. A friend looks sad. Ask casually, "What's wrong?"

Show answer

どうしたの? — the casual default. The の invites an explanation and softens the question.

2. You ask a coworker you don't know well, politely, "What's wrong? You look pale."

Show answer

どうしたんですか。顔色かおいろが悪わるいですよ。 — んですか is the polite version of の. 悪わるい here describes the person's condition, so it is fine.

3. A friend is crying. Which is the caring question: どうしたの? or 何なにが悪わるいの?

Show answer

どうしたの? — it asks about the person. 何なにが悪わるいの? asks which part of something is at fault, so it would sound like an objection.

4. Someone criticises your plan and you push back: "So what's wrong with it?!"

Show answer

何なにが悪わるいの? — here the defensive tone is exactly what you want. Same words as the word-for-word "What's wrong?", opposite meaning.

5. Your friend has just missed the train. Ask, "What happened?"

Show answer

どうしたの? (or 何なにがあったの?) — した is the past tense, so you are asking about a situation that has already occurred.

6. Your friend says they can't decide where to go. Ask, "So what are you going to do?"

Show answer

どうするの? — する is the non-past, so you are asking about a decision still to come. One letter apart from どうしたの, opposite direction.

7. You sense a mood change but do not know why. What gentle question opens the door?

Show answer

何なにかあった? — it asks only whether something happened, leaving the person room to say yes or no.

8. A friend answers your どうしたの? with a sulky "Nothing." Give two natural ways they might say it.

Show answer

何なんでもない / 別べつに — both deflect. 別べつに is shorter and can sound colder. If they trail off with ちょっとね…, they are inviting you to ask more.

9. Your speaker is not working. Ask, "What's wrong with it?"

Show answer

どこが悪わるいの? — どこ points to the location of the fault, and 悪わるい describes a condition. It asks "which part is the problem?", not "who is to blame?".

Use a trial lesson to ask a friend どうしたの? and a colleague どうしたんですか?, and steer clear of the angry-sounding 何なにが悪わるい?.

FAQ

Is どうしたの rude to say to a teacher? Yes, in that form it is too casual. Use どうしたんですか or どうされましたか with a teacher, a boss or someone older. どうしたの is for friends, family and people younger than you.

Does どうしたの always mean something bad happened? No. It just asks what happened to produce the current state. どうしたの、その髪型かみがた! can express surprise at a new haircut, positive or negative. Tone and face tell you which.

Is 大丈夫だいじょうぶ? a good replacement for "What's wrong?" Sometimes. It works in the moment of a stumble or a cough. When you want the person to explain, 大丈夫だいじょうぶ? alone often gets an automatic 大丈夫だいじょうぶ, so follow up with どうしたの or 何なにがあったの.

How do I answer どうしたの if nothing is wrong? Say 何なんでもない or 大丈夫だいじょうぶ. If something is bothering you but you are not ready to explain, ちょっとね… or 実じつはね… ("Actually...") signals that you do want to talk.

What is the difference between 何なにがあったの and どうしたの? どうしたの reacts to a visible state; 何なにがあったの asks about an event. どうしたの fits a friend who looks down. 何なにがあったの fits a friend who walks in bruised or in tears and you want the story.

Can 何なにが悪わるい ever be a caring question? Only in set patterns where 悪わるい means condition. 具合ぐあいが悪わるいの? and どこが悪わるいの? are fine. 何なにが悪わるいの? on its own almost always sounds defensive.
