ドキドキ

• Reading: ドキドキ
• Romaji: dokidoki
• Pronunciation: /do.ki.do.ki/

Meaning

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.

Examples

1. 好きな人に話しかけるときドキドキする。 My heart pounds whenever I try to talk to my crush.
2. 発表の順番が近づいてきてドキドキしてきた。 My turn to present is getting closer and my heart is starting to race.
3. ジェットコースター乗る前のドキドキがたまらない。 The heart-pounding feeling right before getting on a roller coaster is the best.

• 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)
