While there might not be a formal law against talking on the phone in public, it’s a strongly held social norm in Japan that people don’t answer their phones in public. As Ashley Ogawa Clarke notes on the Mr Porter website, it’s about showing respect for others and maintaining a sense of shared peace in public spaces.”

Next time your phone rings in a crowded area, consider hitting mute. “Public phone calls are a big no-no in Japan and on the train and bus you’ll often hear announcements warning against it,” Lucas says. “This is a courtesy to other people — no one wants to hear your phone chat, especially first thing in the morning on the way to work.

Indeed, Japanese culture places a high value on ‘wa’ (harmony) and minimizing disruption to others. This translates to a strong sense of consideration for those sharing public spaces. Loud noises, including phone conversations, are seen as intrusive and disrespectful. You will often see signs and hear announcements reinforcing this etiquette.
