Angry in Japanese: 怒おこる, ムカつく, キレる — and why 怒どい is not a word

Angry in Japanese is 怒おこっている (okotte iru), from the verb 怒おこる (okoru): "angry" is not an adjective at all in Japanese, so "I'm angry" is 怒おこっている, and 私わたしは怒どい is simply not a word.

English gives you one adjective, "angry," and you can stretch it from mildly annoyed to furious. Japanese splits the same territory across a verb, a passive form, slang, a mimetic word and an idiom, and each one tells the listener something different about how you are angry and who you are talking to. Here is the map.

The basics

How do you say "I'm angry" in Japanese?

Say 怒おこっている (okotte iru), or 怒おこってる in speech. 怒おこる is a verb meaning "to get angry," and the ている form describes the state you are currently in.

怒おこってる? — Are you angry? (casual, the ている shrinks to てる) 怒おこっていません。 — I'm not angry. (polite, plain denial)

If the ている idea feels slippery, our guide to the teiru form explains why "is angry" is a state here, not an action in progress. The short version: the anger already started, and you are still in it.

Why is 怒どい wrong?

Because there is no い-adjective 怒どい. English speakers expect "angry" to be an adjective, so they reach for one, and the mistake is very common in lessons. The correct pattern is verb + ている.

先生せんせいは怒おこっています。 — The teacher is angry. (polite, correct) 先生せんせいは怒どいです。 — ✗ Not Japanese. (the form does not exist)

The noun is 怒いかり (ikari, "anger"), and 怒いかりっぽい (okorippoi) is a real adjective meaning "short-tempered." Those exist. 怒どい does not.

What is the difference between 怒おこる and 怒おこられる?

怒おこる is what you do. 怒おこられる is the passive: someone got angry at you, so you were told off. In everyday Japanese, 怒おこられた is the normal way to say "I got scolded."

母ははに怒おこられた。 — I got yelled at by my mom. (casual, passive, said by the person who was scolded) 母ははは怒おこっている。 — My mom is angry. (casual, plain state)

English also uses a passive here ("got scolded"), and Japanese does the same with the passive form られる you meet elsewhere. Japanese passives often carry a sense that the event was unwelcome, so 怒おこられた carries a little sigh with it.

What is the difference between 怒おこる and 叱しかる?

Both mean "to scold," but they differ in who is talking and why. 叱しかる (shikaru) is what someone with authority does for the other person's good: a teacher, a parent, a boss correcting a mistake. 怒おこる is closer to losing your temper because you are upset.

先生せんせいは生徒せいとを叱しかった。 — The teacher scolded the student. (polite-neutral, correction from above) 彼かれは理由りゆうもなく怒おこった。 — He got angry for no reason. (plain, emotion-driven)

You will not usually hear 叱しかる about a friend. If a friend scolded you, that would be 怒おこる, or more likely 怒おこられた.

Beyond the basics

What do ムカつく, イライラする and 腹はらが立たつ mean?

These are the words people actually use for everyday anger, and each describes a different feeling.

ムカつく (mukatsuku) is slang for "that makes me mad," with a sense of disgust or nausea. It is usually about something or someone that provokes you.

あいつ、マジでムカつく! — That guy really pisses me off! (casual slang, rough, friends only)

イライラする (iraira suru) is an onomatopoeia-style word for irritation that builds up, like being stuck in a slow line. It is closer to "on edge" than to a single blow-up. The word type is explained in our giongo and gitaigo guide.

電車でんしゃが遅おくれてイライラする。 — I'm irritated because the train is late. (neutral, safe in most settings)

腹はらが立たつ (hara ga tatsu) is the idiom, literally "the stomach stands up." It is a serious, general-purpose "that made me angry," and it is safe in both speech and writing.

その言い方いいかたには腹はらが立たった。 — That way of saying it made me angry. (neutral, slightly formal-sounding)

What does キレる mean?

キレる (kireru) is "to snap." The anger is not slow, it is a sudden break. The verb 切きれる is "to be cut," and キレる is the katakana form for the emotional version. It is often used for someone who explodes with little warning.

部長ぶちょうがついにキレた。 — The department head finally snapped. (casual, a sudden outburst) ブチ切きれた! — I totally lost it! (slang, very strong)

Younger speakers also say おこ (oko, a clipped 怒おこっている) or 激げきおこ (geki-oko, "super mad"), often playfully. Treat those as teen slang and avoid them at work.

How does anime show anger?

Anime loves the gap between what a character says and what their face shows. The classic line is 怒おこってないよ ("I'm not angry"), delivered with a smile that clearly means the opposite. The ている negative is the hook: she is denying the state of being angry while radiating it.

怒おこってないよ。 — I'm not angry. (casual, said with a scary smile, very common in anime) もう、ぷんぷん! — Geez, I'm so mad! (cute, playful, ぷんぷん is the puffed-cheek sound)

ぷんぷん (punpun) is a mimetic word for a mild, cute, slightly childish anger. A character who says it is usually pouting, not dangerous. That is a very different energy from キレる.

Common mistakes

  • Saying 怒どいです. No such adjective. Use 怒おこっています or 怒おこっている.
  • Using 怒おこる when you mean "I was scolded." That is 怒おこられた, the passive.
  • Using 叱しかる for a friend's anger. 叱しかる needs a teaching or authority angle.
  • Using ムカつく in a formal setting. It is rough slang. In a meeting, avoid naming the emotion; say what the problem is instead (例れい: 困こまります, 対応たいおうをお願ねがいします).
  • Forgetting that 怒おこる sounds strong. In English, "I'm angry" can be mild. In Japanese, 怒おこっている says the anger is real. For mild annoyance, イライラ or ちょっとムカつく fits better.

FAQ

Is there a Japanese adjective for "angry"? Not a common one. The everyday way is the verb 怒おこる, so you say 怒おこっている. 怒いかりっぽい exists, but it means "short-tempered," not "angry right now."

How do you say "Don't be angry" in Japanese? 怒おこらないで (okoranai de) is the casual request, and 怒おこらないでください is polite. It is a gentle plea, common between friends or in family conversations.

Can 怒おこられる mean "get angry"? No. 怒おこられる means to be the target of someone's anger. If you get angry yourself, it is 怒おこる or 怒おこっている.

Is ムカつく rude? It is casual slang and can sound rough. Among friends it is fine. Avoid it with teachers, customers or anyone above you.

What is the difference between 怒おこる and キレる? 怒おこる is anger in general, and it can be quiet. キレる is a sudden explosion, so use it only when the change is abrupt.

Practice

Build each answer before opening it. Questions 3 and 4 are a pair, and the same verb changes direction.

1. How do you say "My teacher is angry" in polite Japanese?

Show answer

先生せんせいは怒おこっています — 怒おこる is a verb, and ている (polite: ています) gives the state "is angry." There is no い-adjective 怒どい.

2. Why is 私わたしは怒どいです wrong?

Show answer

怒どい is not a Japanese adjective. The idea of "angry" is carried by the verb 怒おこる, so you need 怒おこっています.

3. Say "My mom is angry" in casual Japanese.

Show answer

母ははは怒おこっている — the active verb, so mom is the one with the anger. This pairs with question 4.

4. Say "I got scolded by my mom" in casual Japanese.

Show answer

母ははに怒おこられた — the passive られる puts you on the receiving end, and に marks who did the scolding. Same verb as question 3, opposite direction.

5. A teacher corrects a student's mistake for the student's good. Which verb fits best, 怒おこる or 叱しかる?

Show answer

叱しかる — it describes correction from a position of authority, done for the other person's benefit. 怒おこる would sound more like a personal temper.

6. Which word describes anger that builds slowly, like being stuck in a slow line: ムカつく or イライラする?

Show answer

イライラする — it is an irritation word for feeling on edge. ムカつく is sharper, and it points at a specific thing or person that provoked you.

7. Which word means "to snap," a sudden explosion of anger?

Show answer

キレる — it is built on the idea of something being cut. 部長ぶちょうがキレた means the boss suddenly lost it.

8. Give the idiom with the literal meaning "the stomach stands up," meaning "that made me angry."

Show answer

腹はらが立たつ — a general-purpose idiom that is safe in both speech and writing.

9. In an anime, a character smiles and says 怒おこってないよ. What does she likely mean?

Show answer

The opposite: she is angry. The literal words deny the state of anger, but the scary smile signals the reverse. It is a stock anime joke.

10. Which one would you say to a friend who is pouting, ぷんぷん or キレる?

Show answer

ぷんぷん — it describes cute, mild anger like puffed cheeks. キレる would mean a serious sudden outburst.

怒どい is a common early slip, so in a trial lesson, describe a time you were annoyed and choose among 怒おこる, ムカつく and イライラ for how strong it really was.
