ドキドキ

Japanese Slang Japanese ★★★★★ 5/5 neutral ドキドキdokidoki

読み ドキドキ

ローマ字 dokidoki

発音 /do.ki.do.ki/

意味

The sound and feeling of a pounding heart — used for nervous excitement, romantic fluttering, anxiety, or thrill.

ドキドキ is the quintessential Japanese onomatopoeia for a racing heart. Unlike ワクワク (purely positive excitement), ドキドキ is versatile — it covers romantic butterflies, exam nervousness, horror suspense, and athletic adrenaline. It is deeply embedded in manga, anime, and everyday speech. The game 'Doki Doki Literature Club' made the term internationally known.

医療の文脈で「ドキドキする」と言うと動悸と混同される場合がある (In medical contexts, 'dokidoki suru' may be confused with palpitations — specify if casual or clinical)
