Most of it is common sense. A few things aren't obvious — those are worth knowing.
Japan isn't strict in the way people expect. Nobody will lecture you. But breaking unwritten rules creates friction — and following them makes your trip noticeably smoother.
This isn't an exhaustive list. It's the things that actually come up.
No phone calls. Keep music inaudible. Conversations in a low voice. It's not a rule — it's just what everyone does.
Pink seats near the doors are for elderly, pregnant, or disabled passengers. Sit elsewhere if possible. On crowded trains, give them up without being asked.
Fine on Shinkansen. On city subways and local trains, it's frowned upon. Drinks in closed containers are usually acceptable.
Take your backpack off and hold it in front of you or place it on the overhead shelf. It takes up space and hits people otherwise.
Platforms have painted lines showing where to stand. Everyone lines up. Join the queue, don't push through.
Use the water basin (temizuya) at shrine entrances. Scoop water with the ladle, rinse both hands, then your mouth. Not mandatory, but respectful.
A small, natural bow at the torii. Nobody expects deep formality from tourists, but the gesture is noticed.
Temples are active religious spaces, not just photo backdrops. Lower your voice. Put the phone down for a moment.
Many interiors prohibit photos. Look for signs or follow what other visitors do. When in doubt, ask.
This is the central rule. Sit at the shower station, wash thoroughly, rinse off completely. Only then get in the communal bath.
Small towels are for modesty and drying only. Fold them on your head or set them aside. They don't go in the bath.
Traditional onsen baths are nude. This is non-negotiable in most places. Some tourist facilities offer swimwear options — check in advance.
Many onsens prohibit visible tattoos. Some tourist-facing facilities now allow them. Check before you go if this applies to you.
Onsens are for relaxation. Loud conversations, splashing, or running aren't welcome.
Eating on the street is uncommon and mildly frowned upon — except at festivals or in specific food market areas. Eat at a bench or inside the shop.
Optional for tourists, but appreciated. It's a brief acknowledgment before a meal. Just a small moment.
Tipping is not done in Japan. Leaving money on the table can confuse or embarrass staff. Good service is the standard — no additional payment expected.
Unlike in most Western countries, slurping ramen or soba is normal and even signals enjoyment.
Don't stick chopsticks upright in rice (funeral connotation) and don't pass food chopstick-to-chopstick (same reason). Use the serving end to take from shared dishes.
Public bins are rare. You're expected to carry your rubbish and dispose of it at your accommodation or a convenience store bin.
Escalators: stand on the left, walk on the right (except in Osaka where it's reversed). Sidewalks: keep left.
At many traditional restaurants, ryokans, temples, and some homes, shoes come off at the entrance. A step up in the floor usually signals this.
Lines form and are respected — at stations, restaurants, convenience stores, everywhere. Don't cut.
