On trains or airplanes, passengers sitting next to you may intentionally or unintentionally encroach on your personal space. Some people immediately speak up to warn them, but in Japan, there's a gentler — yet seemingly quite effective — method you can try.

Recently, cosplayer Satomi Ishihara posted a tweet about a flight where the young man in the seat next to her kept getting closer, severely invading her personal space and making her uncomfortable. She remembered seeing a tweet that said: “On the train, there was a man spreading his legs, but when I opened an English newspaper, he closed them.” So she opened an English article on her laptop and pretended to read — and the guy gradually moved away.
In fact, this theory has long circulated online: reading English on public transportation creates an invisible barrier between you and other Japanese passengers. Many netizens have shared their own experiences, such as: “If you can read while taking (English) notes, the effect doubles!” However, some have almost been caught out: “I tried this trick too, but then a tourist came over to ask me for directions. My English isn’t that great.”

This phenomenon is believed to be related to Japanese people’s fear of interacting with foreigners. There’s a common stereotype among Japanese that foreigners might strike up a conversation with anyone at any time. To avoid being pulled into a chat — especially in a language they’re not familiar with — people often leave seats next to foreigners empty on public transport. The Japanese call this the “empty seat” effect.
