Meaning

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.

Examples

1. 歩きスマホはマナー違反だって知ってる？ Did you know that texting while walking is considered bad manners?
2. 電車の中で大声で電話するのはマナー違反。 Talking loudly on the phone on a train is an etiquette violation.
3. 観光地でのマナー違反が問題になってるよね。 Etiquette violations at tourist spots have become a real problem.
