先輩

• Reading: せんぱい
• Romaji: senpai
• Kanji breakdown: 先 (ahead/previous) + 輩 (companion/colleague) → one who came before; senior
• Pronunciation: /seɴ.pa.i/

Meaning

A senior student, upperclassman, or someone more experienced in a shared context like school, work, or a club.

先輩 is one of the most fundamental social relationship terms in Japanese culture. In schools and universities, it refers to students in higher grades. The 先輩/後輩 dynamic dictates behavior — 後輩 are expected to show respect, use polite language, and defer to 先輩. This hierarchy extends to workplaces and any shared organization. In recent pop culture, 'senpai' has also become known globally through the 'notice me senpai' meme.

Examples

1. 先輩に敬語使わないとめっちゃ怒られるんだよ。 If you don't use polite language with your senpai, you'll get seriously scolded.
2. 部活の先輩が引退して寂しくなった。 I felt lonely after my senpai retired from the club.
3. バイト先の先輩がすごく優しくて助かってる。 The senpai at my part-time job is super nice, and it's been a huge help.
