マナー違反

意味

Bad manners, etiquette violation — behaviour that breaks unwritten social rules, especially by tourists or in public spaces.

Japan has extensive unwritten social rules, and マナー違反 is the term used to call out breaches. Common examples include eating while walking, talking loudly on trains, blocking pathways for photos, and littering. The term is especially prominent in discussions about tourist behaviour but applies to anyone. Japanese people are generally conflict-averse, so マナー違反 is more often discussed than directly confronted.

例文

1. 歩きスマホはマナー違反だって知ってる？

3. 観光地でのマナー違反が問題になってるよね。
