正解（せいかい） means “correct answer” or “right answer.” It’s one of those satisfying words you’ll hear in quiz shows, classrooms, and everyday conversations when someone gets something right. Let’s look at all the ways it’s used.

Basic Uses of 正解

正解！ on its own is the most natural way to say “Correct!” or “That’s right!” in Japanese:

• 正解！その通りです。— Correct! That’s exactly right.
• はい、正解です。— Yes, that’s the correct answer.
• 残念、不正解です。— Too bad, that’s incorrect.
• 全問正解した！ — I got every question right!
• 正解率は80%でした。— The correct answer rate was 80%.

正解 Beyond Tests: Everyday Situations

Native speakers use 正解 in casual conversation far beyond exams — whenever someone makes the right call or guesses correctly:

• その選択、正解だったね。— That was the right choice, wasn’t it.
• 傘を持ってきた。正解だった。— I brought an umbrella. Good call.
• 早めに予約したのは正解だったよ。— Reserving early was the right move.
• あのレストランをやめたのは正解だった。— It was a good call to skip that restaurant.
• 彼に頼んだのは正解だったと思う。— I think asking him was the right decision.
