Using mobile phones on trains However, you should be cognizant that your phone use does not disturb others. Never talk on your phone while on the train, unless using the designated phone area of the shinkansen. Silence and use headphones so that your media cannot be heard by others.

In 2026, talking on the Japanese bullet train (Shinkansen) is permitted, but it is governed by a very strict social etiquette of quietness. While you can have a conversation with your travel companions, you are expected to use a "whisper voice" so as not to disturb other passengers, many of whom use the quiet environment to sleep or work. The most important rule in 2026 is that cell phone calls are strictly prohibited at your seat. If your phone rings, you should have it on "Manner Mode" (silent) and immediately move to the "deck" area—the space between the train cars near the toilets and trash bins—to conduct your conversation. This ensures that the passenger cabin remains a peaceful "Quiet Zone." If you are speaking too loudly, you may receive a polite but firm look from other passengers or a gentle reminder from the conductor. This culture of consideration is a hallmark of Japanese travel; while the Shinkansen is a place where you can enjoy an ekiben (lunch box) and a chat, the volume must remain significantly lower than what you might find on a train in the United States or Europe.
