アツい

Japanese Slang Japanese ★★★★ 4/5 casual あついatsui
Reading あつい
Romaji atsui
Pronunciation /a.tsɯ.i/

Meaning

Fired up, passionate, or intense — not about temperature, but about someone's burning enthusiasm.

When written in katakana as アツい, this word shifts from its literal meaning of 'hot' (暑い/熱い) to describe someone who is passionately fired up about something. An アツい person gives 110%, delivers impassioned speeches, or throws themselves into a cause with visible intensity. It can be admiring (wow, they really care) or slightly teasing (they're being a bit much). Common in sports, anime fandom, and workplace contexts where someone is noticeably more enthusiastic than the norm.

Examples

  1. あの監督のスピーチがアツすぎて全員泣いた。 That coach's speech was so fired up that everyone was in tears.
  2. アツい男だよね、何でも全力でやるから。 He's such a passionate guy — he goes all out in everything he does.
  3. アツい展開が好きだからスポーツ漫画ばっかり読んでる。 I love intense storylines, so I only read sports manga.
