One of the first things foreigners notice when they come to Japan is how quiet the trains are.
Hundreds of people packed into a single car, yet it feels like a library. Nobody is on the phone. Nobody is talking loudly. Why are Japanese people so quiet on trains? Is it a rule, or is it culture?
The answer is both. And understanding the background behind it reveals something fundamental about Japanese society.
The Culture of “Reading the Air”
In Japan, there is a concept called “kuuki wo yomu” — literally, “reading the air.” It means sensing the atmosphere of a situation and adjusting your behavior accordingly. On a train, many people are tired from work, heading to an early morning meeting, or simply trying to rest. In that kind of space, staying quiet is naturally expected as a form of consideration for others.
This is not written down as a rule anywhere. But Japanese people absorb this sense from a very young age. Being loud on a train is understood as a lack of respect for the people around you.
Why Phone Calls Are Not Allowed
Making phone calls on Japanese trains is generally considered bad manners. There are clear reasons for this.
One is consideration for people who use pacemakers. In the past, mobile phone signals were believed to potentially interfere with pacemakers. While technology has improved significantly since then, the habit has remained as a cultural norm.
The other reason is the discomfort a one-sided conversation creates. Two people talking feels natural, but hearing only one side of a phone conversation is jarring and intrusive for those nearby.
The Concept of Priority Seating
Every train in Japan has “priority seats” — designated for elderly passengers, pregnant women, people with disabilities, and those with injuries.
Near priority seats, it is recommended to turn your phone to silent or switch it off entirely. Again, this comes from the longstanding consideration for pacemaker users.
You may also notice that priority seats are sometimes empty even on a crowded train. This is because people want to be ready to give up the seat at any moment. Even outside of priority seats, offering your seat to someone who needs it is considered basic courtesy in Japan.
Unwritten Rules During Rush Hour
Tokyo’s morning rush hour is famous worldwide. Somehow, despite the incredible crowding, everything remains orderly. This is because of several unwritten rules.
Backpacks should be held in front of you or placed on the overhead rack — a large bag on your back takes up space and bumps into other passengers. Sound leaking from headphones is also frowned upon. And if you are standing near the doors, it is expected that you will step off the train briefly to let other passengers exit, then reboard.
What About Eating and Drinking?
On bullet trains and express services, eating and drinking is generally acceptable. But on regular commuter trains, it is considered bad manners. Strong-smelling food in particular should be avoided. Even drinking coffee during the morning commute can attract disapproving glances.
The Quiet Is Not Coldness
Some foreigners interpret the silence of Japanese trains as coldness, or a lack of human warmth. But this is a misunderstanding.
The quiet on Japanese trains is an expression of consideration for strangers. The constant awareness of “am I inconveniencing the people around me?” is what creates that silence.
Once you understand that, the Japanese train is no longer just a way to get from A to B. It becomes a small window into Japanese society itself.
