Scary in Japanese: 怖こわい means both scary and scared

"Scary" in Japanese is 怖こわい (kowai) — and 怖こわい also means "scared," so the same word covers "this movie is scary" and "I'm scared."

English forces you to pick between scary and scared. Japanese does not, and that is exactly where learners get confused: you hear 怖こわい and cannot tell whether the thing is frightening or the speaker is frightened. The good news is that the sentence almost always tells you, and once you see how, the rest of the "fear vocabulary" (怖こわがる, 恐おそろしい, ゾッとする, ビビる) slots in around it.

The basics

How do you say "scary" in Japanese?

Say 怖こわい (こわい), an い-adjective. Put the scary thing first and 怖こわい last.

このホラー映画えいがは怖こわい。 — This horror movie is scary. (casual, describing the thing) あの家いえ、ちょっと怖こわいですね。 — That house is a little scary, isn't it? (polite, small talk)

The negative is 怖こわくない ("not scary") and the past is 怖こわかった ("was scary"). Like any い-adjective, it also connects with て: 暗くらくて怖こわい, "dark and scary."

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

Also 怖こわい. The difference is what you are afraid of, and it is marked with が.

私わたしは犬いぬが怖こわい。 — I'm scared of dogs. (casual, literally "as for me, dogs are scary") 暗くらいところが怖こわいです。 — I'm scared of dark places. (polite)

Literally, Japanese says the thing is scary to me. There is no separate "scared" adjective, so 犬いぬが怖こわい and 犬いぬは怖こわい both come from the same word. If you say 私わたしは怖こわい on its own, people will usually understand "I'm scared" from the situation, but strictly it could also be read as "I am scary." When you mean "I'm scared," name what you're scared of: 〜が怖こわい.

How can you tell scary from scared?

Look at the marker before 怖こわい.

Pattern Reads as Example
Thing は 怖こわい that thing is scary 幽霊ゆうれいは怖こわい — ghosts are scary
Person は Thing が 怖こわい that person is scared of the thing 私わたしは幽霊ゆうれいが怖こわい — I'm scared of ghosts
怖こわい + noun scary ___ 怖こわい話はなし — a scary story

If there is a が phrase, someone is scared. If it is just は and a thing, the thing is scary. Context fills in the rest, the same way it does for other feeling words like the ones in our Japanese words for happy guide.

Beyond the basics

How do you say someone else is scared?

Use 怖こわがる (こわがる). Feeling adjectives like 怖こわい are for your own feelings, or for questions to the other person. To describe what a third person feels, add 〜がる, which means "shows signs of feeling X."

弟おとうとはお化ばけを怖こわがっている。 — My little brother is scared of ghosts. (casual, describing someone else) 怖こわがらないで。 — Don't be scared. (casual, comforting someone)

Two handy relatives: 怖こわがり is a scaredy-cat (彼かれは怖こわがりだ, "he's a scaredy-cat"), and 怖こわがらせる means "to scare someone" (人ひとを怖こわがらせる). Careful: 彼かれは怖こわい literally means "he is scary," not "he is scared." That is a common slip. To name the scariness itself rather than anyone's reaction, use the noun 怖こわさ, as in 高たかさの怖こわさに慣なれた ("I got used to how scary the height was"), and fear in Japanese sets it beside the stronger 恐怖きょうふ.

When do you use 恐おそろしい instead?

恐おそろしい (おそろしい) is the heavy, formal cousin: terrifying, dreadful. It is for disasters, crimes, and things with real weight, not for a haunted house at a theme park.

恐おそろしい事件じけんが起おきた。 — A terrifying incident happened. (formal, news-style) 恐おそろしいほどの静しずけさだった。 — The silence was eerie, almost terrifying. (literary)

In anime, villains and narrators love it. In daily conversation, saying 恐おそろしい about a spider will sound comically dramatic.

What are ゾッとする and ゾクッとする?

These are sound-symbol words (擬態ぎたい語ご) for the physical shiver. ゾッとする is the cold horror that runs down your spine. ゾクッとする is a quicker, sharper shiver, and it can also be thrilling, not only frightening. If you want the bigger picture of how these words work, see our guide to Japanese onomatopoeia.

その話はなしを聞きいてゾッとした。 — I got chills hearing that story. (casual, horror or disgust) 予告編よこくへんだけでゾクッとした。 — Just the trailer gave me a shiver. (casual, could be fear or excitement)

How do you say "scary" in slang?

Two forms are worth knowing. ビビる is slang for "to get scared, to chicken out," and it usually sounds a bit self-mocking. 怖こわっ! is 怖こわい with the final い dropped, an instant reaction like "yikes!"

お化ばけ屋敷やしきでビビった。 — I got scared in the haunted house. (casual slang) 怖こわっ! いきなり出でてこないで! — Yikes! Don't jump out at me! (casual, a reflex reaction)

This clipped い-drop works for many adjectives in casual speech (すごっ、うまっ), and it is a tone marker as much as a meaning.

What if you don't want to say "I'm scared"?

Say 苦手にがて (にがて): "not good with, weak at." It is the soft, polite way to admit fear, and it dodges the drama of 怖こわい.

虫むしが苦手にがてです。 — I'm not good with bugs. (polite, softer than saying you're scared) ホラーはちょっと苦手にがてで… — Horror isn't really my thing... (polite, trailing off as a soft refusal)

苦手にがて is the same word we cover in 上手じょうず, 得意とくい, 下手へた and 苦手にがて, used here for "I'd rather avoid it." Many Japanese people will say 苦手にがて where an English speaker says "I hate / I'm scared of."

What does 怖こわいくらい mean?

〜くらい怖こわい and 怖こわいほど can be an intensifier: "so [adjective] it's almost scary." Here the fear is not literal; it just means "extremely."

怖こわいくらい高たかい。 — It's scarily expensive / high. (casual, "so high it's almost scary") 怖こわいほど上手うまい。 — Scarily good. (casual, praise)

This works like the "extent" くらい we explain in kurai vs gurai: "to the degree of being scary." Once you hear it, you will notice it constantly.

What do you hear in horror anime and games?

Real reactions are short. In horror anime and games you will hear a lot of repeated and clipped forms:

怖こわい怖こわい怖こわい! — Scary, scary, scary! (casual, repeated in panic) これ、怖こわすぎる。 — This is too scary. (casual, すぎる = "too much") もう無理むり、怖こわくて進すすめない。 — I can't take it, it's too scary to keep going. (casual, gaming)

Notice 怖こわくて: the て-form gives the reason. "Too scary to move forward" is 怖こわくて進すすめない. When what you cannot face is a ghost, ghost in Japanese sets the childlike お化ばけ, as in お化ばけ屋敷やしき, against 幽霊ゆうれい, the spirit of a dead person.

Common mistakes

  • Using 怖こわい for a third person's feelings. 彼かれは怖こわい means "he is scary." For "he's scared," say 彼かれは怖こわがっている.
  • Dropping the が phrase. 私わたしは怖こわい leaves everyone guessing. Say 何なにが怖こわいか: 犬いぬが怖こわい.
  • Overusing 恐おそろしい. It is heavy and formal. For a scary movie or a spider, 怖こわい is the natural word.
  • Answering "Are you scared?" with 怖こわくありません all the time. It is polite and correct, but 大丈夫だいじょうぶ or 平気へいき sounds more natural.

Which word for which situation?

Word Formality When to use it
怖こわい Neutral, everyday Movies, dogs, heights, "scary" and "scared"
怖こわがる Neutral Describing someone else's fear
恐おそろしい Formal, heavy News, disasters, villains in stories
ゾッとする / ゾクッとする Casual to neutral The physical shiver, horror or thrill
ビビる Slang, casual Chickening out, jokes among friends
怖こわっ! Very casual An instant "yikes" reaction
苦手にがて Polite, soft Admitting fear without drama

FAQ

Is 怖こわい always "scary," or can it be "scared"? Both. 怖こわい is the thing being scary (映画えいがが怖こわい) or the speaker being scared (犬いぬが怖こわい). The が phrase and the context tell you which.

What is the difference between こわい and おそろしい? こわい (怖こわい) is everyday; おそろしい (恐おそろしい) is heavy and formal, closer to "dreadful."

How do I say "I'm scared" without sounding childish? 苦手にがて is the softest option, and 少すこし怖こわい ("a little scary") also works. ビビる sounds jokey, so save it for friends.

What is the difference between ゾッとする and 怖こわい? 怖こわい names the feeling of fear. ゾッとする describes the physical reaction, the chill, and it can come from disgust as well as fear.

Can 怖こわい be used for people? Yes: 怖こわい先生せんせい is a teacher who is intimidating. It does not mean the person is afraid.

Practice

Build each answer before opening it. Questions 4 and 5 are a pair: the same word going in two directions.

1. Say "This movie is scary."

Show answer

この映画えいがは怖こわい — the thing is the topic (は), and 怖こわい describes it.

2. Say "I'm scared of dogs."

Show answer

私わたしは犬いぬが怖こわい — the が phrase names what you fear, so the sentence reads as "scared," not "scary."

3. What is the problem with 私わたしは怖こわい as a way to say "I'm scared"?

Show answer

It does not say what you fear — it may be understood from context, but it can also be read as "I am scary." Add a が phrase.

4. Say "My friend is scared of ghosts" (describing someone else).

Show answer

友ともだちはお化ばけを怖こわがっている — for a third person, use 怖こわがる, not the bare adjective 怖こわい. This is the pair to question 5.

5. What does 彼かれは怖こわい mean?

Show answer

"He is scary." — 怖こわい describes the person as frightening. It does not say he is afraid; that would be 彼かれは怖こわがっている.

6. Which is right for a news report about a disaster: 怖こわい or 恐おそろしい?

Show answer

恐おそろしい — it is the heavy, formal word for real dread. 怖こわい is for everyday fear.

7. You want to admit you dislike bugs politely, without drama. What do you say?

Show answer

虫むしが苦手にがてです — 苦手にがて is the soft way to say you are not good with something, and it avoids the drama of 怖こわい.

8. What does 怖こわいくらい高たかい mean, and is anyone actually scared?

Show answer

"Scarily high / expensive." — くらい marks the degree, "so high it is almost scary." Nobody needs to be afraid; it is an intensifier.

9. You jumped when a ghost appeared in a game and shouted a one-word reaction. Which form fits: 怖こわい or 怖こわっ!?

Show answer

怖こわっ! — the dropped い gives an instant, casual "yikes!" reflex. 怖こわい is the full form.

Use a trial lesson to say この映画えいがは怖こわい about a film and 怖こわくて動うごけない about yourself, and see how one word covers both scary and scared.
