Why Japanese trains are quiet, and what is actually allowed

At 8:20 on a Tuesday morning in March I stood in a Yamanote line car with about 80 other people and counted the noises for nine stops. Door chimes, the announcement, two phone buzzes, one cough. That was the whole list.

Visitors expect a rule book, and I did too when I moved to Fukuoka in 2021. There is no single one. A few parts are posted rules, most of it is habit, and the posted rules are the ones that cost foreigners money. I ride JR and subway trains most days, and I got several things wrong in Tokyo in March and Osaka in August 2026. This is what I learned, with the prices I paid.

People talk on Japanese trains. Schoolkids talk, couples talk, tour groups talk, and nobody minds. The volume is pitched so that only the person next to you hears it. On the Shinkansen, a conversation at the level you would use at a library table is fine, and I have sat through whole rides next to friends chatting about their weekend.

What draws attention is sound that has no one to talk to: a phone call, a video playing without headphones, leaking music from earbuds turned up too high, a loud laugh at a screen. Announcements in Japanese and English on JR lines ask passengers to set their phones to silent, which is called manner mode, and to refrain from calls. That request is the closest thing to a posted rule on the subject.

I am a German in Fukuoka, not an anthropologist, so take this as one resident's reading. Commuter trains in big cities are full for hours a day, and strangers stand closer than most Europeans would accept. Silence gives everyone a bit of privacy in a small space. There is also a word, meiwaku, for causing trouble for other people, and it covers a lot of small things in public: noise, smells, bags in the aisle, a seat held for a friend.

The railways reinforce it. Operators have run poster campaigns on manners for decades, and the posters are charming and tell you very little. They show a cartoon of someone doing something wrong, and you have to guess what. The announcements are clearer, but they come once and fast. The rules with fees attached are the ones that are poorly signed, as you will see in the luggage section.

Keep your phone on silent in every car. Take calls on the deck of a Shinkansen, the small area between cars near the doors, or at the station. On a local train, text instead. No speakerphone, no video calls, no voice messages played aloud. A phone bought in Japan makes a shutter sound that you cannot turn off, and yours probably does not. Do not photograph the car or the people in it anyway.

I made the mistake in August on the Midōsuji line between Namba and Shin-Osaka. A hostel rang about my check-in time, I answered and spoke for about 25 seconds. Nobody said a word. The woman across the aisle closed her book, the man beside me shifted a half step away, and two stops later the car was quieter than before I picked up. I have not answered a call on a train since. If it is urgent, get off at the next station and call back from the platform.

On the Shinkansen, eating is normal, and it is part of the ride. Stations sell ekiben, boxed meals made for trains, and a good one costs about ¥1,000 to ¥1,500. If you are on a budget, as I usually am, a convenience store rice ball is about ¥150 to ¥250 and a bottle of tea is about the same, so lunch is under ¥500. Buy it before you board and do not count on a snack trolley. The trash bins are on the deck between cars. Skip anything with a strong smell, such as fried fish or a sandwich with a lot of onion, in a closed car.

Limited expresses such as the Narita Express and long-distance trains with pairs of forward-facing seats work the same way. A canned beer on the Shinkansen is routine. Being drunk and loud is not. On Friday nights on late trains the standards loosen and conversation gets louder, so that is the one time you can relax.

Commuter lines are different. There is no rule against eating, and a drink from a bottle is fine, but you will almost never see anyone eat. I did it in March on the Chūō line at 9:40am, after the morning peak, with a chicken katsu sandwich. Three bites in, I saw that I was the only person in the car eating. A man two seats away moved to the next row. It was not hostile. It was just what the car did, and I put the sandwich away.

This is the one place where Japan writes down a rule and attaches a fee to it. The rule is on the Tōkaidō, Sanyō and Kyūshū Shinkansen, the line between Tokyo, Osaka, Hiroshima and Fukuoka.

Check the current wording on JR Central's website before you travel, and look at the rules of the operator for any other line. The reservation is free, you pick the seat type when you book, and the space behind the last row is shared by the five people who reserved those five seats. The standard 28-inch check-in case often comes in over 160 cm in total once you count the wheels and the handle. A friend who visited me in August arrived with one that measured 166 cm. We found out at Shin-Osaka, and the conductor charged the ¥1,000 fee on the ride to Hakata. The fee was avoidable. A bag that size also cannot go in the non-reserved cars, so book the seat when you buy the ticket.

Anything of 160 cm or less goes on the overhead rack, in the baggage area at the end of the car, or between your knees and the seat ahead. Do not leave a case in the aisle or the doorway.

On commuter trains the rule is common sense. At rush hour, take your backpack off and hold it in front of you or put it on the rack. I forgot in March on the Chūō line at 8:30, turned around with a 40-liter pack on my back and swung it into a man's arm. He said sumimasen, a polite excuse me, in a tone that meant take it off, and pointed up at the rack. I held the pack in front of me for the rest of the ride.

If you have a big case, avoid rush hour altogether, which means roughly 7:30 to 9:00 on weekday mornings and 17:30 to 19:30 in the evening in Tokyo and Osaka. Forward it instead. Luggage forwarding between hotels costs a few thousand yen per bag and takes a day, and station coin lockers cost about ¥400 to ¥1,000 depending on size and station. Capsule hotels and hostels also hold bags, as our Osaka capsule hotel guide explains.

Priority seats, yūsen-zaseki, are marked in a different color near the doors. They are for older people, people with disabilities, pregnant women, injured passengers and people with small children. You may sit in them when the car is empty. Stand up when someone who needs them boards. Many locals leave them vacant even on a crowded train, and I have started to do the same.

Two badges to know. The Help Mark is a red card with a white cross and a heart, worn by people with conditions you cannot see. The maternity mark is a pink badge worn by pregnant women. If you see either, offer your seat. I did it in August on a nearly empty Midōsuji train at 10am. A woman with a cane boarded at Umeda, I stood, and she thanked me with a small bow and declined. She wanted to stand near the door. I sat back down, and nobody minded either way.

Some lines in Tokyo and Osaka run women-only cars at set hours, usually in the morning rush. There is a pink sticker on the car and a sign on the platform. Men are asked to stay out, and platform staff will tell you if you step in at the wrong time. Children and passengers with disabilities and their carers can ride in them.

Wheelchair users can go to the staffed gate, where staff bring a portable ramp and phone ahead to the destination. On the Shinkansen, check the operator's page for how to reserve a wheelchair space, or ask at the ticket office. Guide dogs and service dogs are allowed on trains.

None of my mistakes got a scolding. Each got the same three things: a look, a small move away, and sometimes a quiet sumimasen. That is usually all you will get, and it is more useful than it sounds, because it tells you what you did and gives you a chance to stop.

The one real telling-off I saw came from train staff, not passengers. On a Hikari in August, a group of travelers played music from a speaker. A staff member asked them twice, politely, to turn it off, and then asked them to move to the deck. Passengers around them watched and said nothing.

If you remember five things, make them these: phone on silent, no calls in your seat, a low voice, eat only where others are eating, and bags off your back at rush hour. If you have a case near 160 cm, measure it before you book. Our JR Pass guide prices the fares, and the first-timer's loop shows where the long Shinkansen legs fall in a 10-day trip, so you know which rides to reserve for the last-row seat.
