代返

意味

Having a friend answer roll call or submit an attendance card on your behalf — a classic act of proxy attendance at Japanese universities.

代返 is a time-honoured tradition of university truancy where a classmate responds to your name during attendance or submits your attendance card while you skip class. While technically against university rules and potentially grounds for disciplinary action, it remains widely practised. With the shift to digital IC card systems and smartphone-based attendance, traditional 代返 has become harder, spawning new creative workarounds.

例文

1. 今日体調悪いから代返お願いしていい？
2. 代返がバレて二人とも欠席扱いにされた。
3. あいつは週3で代返してもらってるのに単位取れてるの謎。
