一発屋

• 読み: いっぱつや
• ローマ字: ippatsuya
• 漢字の分解: 一 (one) + 発 (shot, hit) + 屋 (person, dealer) → one-hit person; one-hit wonder
• 発音: /ip.pa.tsu.ja/

意味

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.
