一発屋

• Reading: いっぱつや
• Romaji: ippatsuya
• Kanji breakdown: 一 (one) + 発 (shot, hit) + 屋 (person, dealer) → one-hit person; one-hit wonder
• Pronunciation: /ip.pa.tsu.ja/

Meaning

A one-hit wonder; an entertainer or artist who had only one big success and then faded from the spotlight.

一発屋 is a widely used label in Japanese entertainment to describe comedians, musicians, or other performers who became massively popular with a single gag, song, or routine but failed to maintain that momentum. While sometimes used affectionately, it often carries a pitying or dismissive nuance. Many Japanese comedians wear the label with self-deprecating humor, and there are even TV specials dedicated to catching up with famous 一発屋.

Examples

1. あの芸人、完全に一発屋だったよね。最近全然見ないし。 That comedian was totally a one-hit wonder, right? Haven't seen them at all lately.
2. 一発屋って言われたくないから、次の曲も全力で作ってる。 I don't want to be called a one-hit wonder, so I'm putting everything into the next song.
3. 一発屋特集の番組って意外と面白いんだよな。 Those TV specials about one-hit wonders are actually pretty entertaining.
