Japan runs on lots of small, unspoken rules designed to keep shared spaces smooth and pleasant. Visitors sometimes trip over these—not out of disrespect, but because the norms aren’t obvious. Here’s a practical guide to common slip-ups and how to avoid them.
1) Shoes & Slippers
What happens: Wearing outdoor shoes onto tatami or into homes/ryokan rooms; forgetting to switch to toilet slippers.
Why it matters: Floors and tatami are kept very clean; toilet slippers keep bathroom germs contained.
Do this instead: Look for a shoe shelf or genkan (entry step). Switch to house slippers; on tatami go barefoot or socks (no slippers). In bathrooms, change into toilet-only slippers, then switch back when you leave.
2) Public Baths (Onsen/Sentō)
What happens: Entering the water unwashed, bringing towels/phones into the bath, wearing swimwear, or overlooking tattoo rules.
Why it matters: Baths are communal and meant to be spotless; some facilities still have tattoo policies.
Do this instead: Wash thoroughly before soaking; keep hair up and towels out of the tub; no phones/cameras; follow posted tattoo guidance (cover sheets or private/“family” baths may be options).

3) Trains & Buses
What happens: Talking on the phone, eating on local trains, blocking doors, taking priority seats, noisy luggage.
Why it matters: Commutes are quiet and packed.
Do this instead: Set your phone to manner mode (silent), no voice calls, keep conversation soft. Queue on platform lines, keep bags in your lap or overhead, and avoid eating except on long-distance trains (e.g., Shinkansen).
4) Lines & Escalators
What happens: Skipping lines; standing side-by-side or walking on escalators.
Why it matters: Order and safety.
Do this instead: Follow floor markings and platform lines. Escalator etiquette varies by region, so the safe bet is to stand, keep to one side, and don’t walk unless signs say it’s allowed.
5) Trash & Recycling
What happens: Leaving trash behind after failing to find a bin, mixing recyclables.
Why it matters: Litter is rare and separation is strict.
Do this instead: Carry a small trash bag with you. When bins appear, sort into burnables, cans, bottles, and PET. If unsure, take it with you.
6) Smoking & Vaping
What happens: Smoking while walking or outside designated areas.
Why it matters: Strict rules protect bystanders and reduce litter.
Do this instead: Use designated smoking areas only (including indoor smoking rooms where permitted). Many streets are no-smoking zones—watch for signs.
7) Restaurants & Shops
What happens: Handing cash directly to staff, asking to split the bill at the register, speaking loudly.
Why it matters: There’s an established flow and consideration for others.
Do this instead: Place cash or cards on the tray; receive change from it. Expect one bill for the table (ask first if you need separate). Important: Some places are cash-only, so carry some cash—preferably small bills and coins—even if you usually pay by card or mobile.
8) Temples & Shrines
What happens: Walking straight down the center under the torii gate, skipping the purification basin, taking photos where prohibited.
Why it matters: These are active religious sites.
Do this instead: At a shrine, bow once before passing slightly to the side of the torii’s center line. At the temizuya: rinse left hand, right hand, mouth (don’t touch the ladle to your mouth), then the handle. Look for no-photo signs inside halls.
9) Noise in Accommodations
What happens: Loud hallway conversations, late-night music, rolling suitcases noisily at night.
Why it matters: Walls can be thin and quiet hours are common.
Do this instead: Keep voices low, avoid late-night suitcase rolling, and respect posted quiet hours.
10) Taxis & Doors
What happens: Opening or slamming taxi doors yourself.
Why it matters: Many taxi doors open/close automatically.
Do this instead: Wait—the driver will operate the door. Exit gently without pushing it shut.
11) Bicycles
What happens: Parking anywhere, riding on crowded sidewalks, using a phone while riding.
Why it matters: Bikes can be impounded and pedestrians have priority.
Do this instead: Park only in designated lots (often paid). Ride with care, use the bell sparingly, and no phone use while riding.
If You Slip Up (It Happens!)
A quick, warm apology goes a long way:
- Sumimasen. (Excuse me / I’m sorry.)
- Shitsurei shimashita. (Pardon my rudeness.)
- Wakarimasen. (I don’t understand.)
- Dōsureba ii desu ka? (What should I do?)
- Eigo wa daijōbu desu ka? (Is English okay?)
