ピカイチ

• Romaji: pikaichi

Meaning

Top-notch, the best of the bunch, number one. Describes something or someone that clearly stands out as the best.

ピカイチ is a lively, slightly old-fashioned slang term that is still widely understood and used. It conveys the idea of being the single standout among a group — the one that shines brightest. While it peaked in popularity in the Showa era, it remains common in casual speech, variety shows, and reviews. It has a cheerful, emphatic quality that makes praise feel genuine and specific.

Examples

1. この店のカレー、この辺ではピカイチだよ。 The curry at this place is the best around here.
2. あの子の歌唱力はクラスでピカイチ。 That girl's singing ability is the best in the class.
3. デザインのセンスがピカイチだね。 Your design sense is top-notch.
