What to know
Read the cubicle symbols before choosing
Japanese restrooms can mark Western-style seated toilets, Japanese-style squat toilets, spray seats, wheelchair-accessible rooms, ostomate equipment, baby chairs, changing tables and care beds separately. The first empty door may not contain the equipment you need.
Choose a standard cubicle when it works for you and leave a multi-function room available for someone who needs its space or equipment. A shared or all-gender symbol can also identify a room suitable for a person using an attendant of another gender; follow the actual sign rather than guessing from the door color.
What to know
A Western-style toilet is used while seated
Lower the seat if necessary and sit facing away from the tank or wall, as on a standard seated toilet. Do not climb onto the seat, squat on it, stand on the lid or place a child on it; the fittings are not designed to support that position.
A heated seat, automatic lid or pre-rinse sound can activate as you approach or sit. That does not mean anything is wrong. Keep loose clothing, straps, phones and small belongings away from the bowl and controls.
What to know
Find the flush control before you need it
The Japan Sanitary Equipment Industry Association documents several current systems: a lever on the tank or pipe, a wall button, a non-contact sensor, a button on the washlet remote or an automatic flush after you stand. Look beside and behind the bowl and on both walls before assuming there is no control.
The standard flush pictogram shows water circling in a toilet bowl. Use 大 (dai, large) for solid waste or a substantial amount of toilet paper; 小 (shō, small) is the reduced flush for urine. The wrong small flush can fail to clear the bowl, so follow the fixture label because paper capacity, button position and color are not universal.
What to know
Confirm an automatic toilet actually flushed
Some toilets flush when you stand, but not every sensor reacts at the same moment. Pause and check the bowl before leaving. If nothing happens, look for a manual button, lever or sensor rather than repeatedly sitting down and standing up.
Do not press every nearby control as a test. A wash button can start a spray, a sound button only plays water noise and an emergency call summons help.
What to know
A spray seat or Washlet is optional and separate from flushing
A spray seat may be controlled from an arm beside the seat or a remote on the wall. The industry’s standard functions include Stop, Rear cleansing and Front cleansing; some models also offer pressure, position, temperature, movement or drying adjustments.
You never have to use these functions. Toilet paper alone is acceptable. Spray seat, electronic bidet and shower toilet are generic descriptions, while WASHLET is a TOTO brand name that is often used informally for the category.
What to know
Operate the spray only while fully seated
Sit back on the seat before pressing Rear or Front. The industry visitor guide says to operate the controls only while seated, use the wash briefly and avoid overuse. Begin at the lowest comfortable pressure because the previous user’s setting may remain.
Press Stop before standing, then use toilet paper or the marked dryer if desired. If no spray appears, do not lean over the bowl to inspect the nozzle or keep pressing controls; the seat sensor, power or water supply may be unavailable.
What to know
A flushing-sound device does not flush the bowl
Some public toilets play running-water sound to mask body noise. It may begin automatically, when you hold a hand over a sensor or when you press a sound button. The sound stops after a set period.
Treat this as optional privacy equipment. After it plays, you still need to use the actual flush control unless the toilet separately flushes automatically.
What to know
Do not confuse the emergency call with the flush
An emergency call can sit close to the wall flush button. Look for 非常 (hijō, emergency), 呼出 (yobidashi, call), a bell, telephone or person-in-distress symbol. Tokyo Metro says its restroom emergency call brings station staff when a user becomes ill.
Use it when you need help, not to test the toilet. If you press it accidentally, remain where staff can contact you and say “Machigai desu. Daijōbu desu”—“It was a mistake; I am okay”—instead of leaving responders to search.
What to know
Used toilet paper goes in an ordinary flush toilet
Japan’s National Consumer Affairs Center tells visitors to flush used toilet paper rather than put it in a trash bin. The toilet-industry guide gives the same instruction for Japanese flush toilets.
Flush only the supplied toilet paper or another product explicitly labeled as flushable. Facial tissue, wet wipes, paper towels, sanitary products, tampons, diapers, packaging and clothing can clog the system even when they look paper-like. Mountain, portable, composting and other special-treatment toilets can use a separate collection process, so their posted instructions override the ordinary flush-toilet rule.
What to know
Other waste follows the marked bin
A small covered bin beside the toilet is generally for the sanitary items named by the facility, not used toilet paper. Wrap the item when appropriate and follow the label; do not force large waste into a small sanitary bin.
Never place trash in an ostomate sink, baby chair, changing table, hand basin or toilet tank. If the facility provides no suitable marked bin, seal the item and ask staff or carry it to an accepted disposal point.
What to know
Use a Japanese-style squat toilet facing the raised hood
A Japanese-style toilet is set into the floor. Place your feet on the marked positions or floor areas beside the bowl, face the raised hood and flush end, lower clothing clear of the bowl, then squat low over the opening. Keep your heels stable and bags away from the wet floor.
Do not sit on the hood or stand on the ceramic rim. If balance, pain, pregnancy, clothing or mobility makes the position unsafe, look for a Western-style or accessible cubicle rather than improvising with the fittings.
What to know
Multi-function toilets have priority equipment
A multi-function room may provide turning space, handrails, an ostomate fixture, baby-changing table, baby chair, fitting board or care bed. Tokyo Metro lists these features, but a particular room may contain only some of them.
Use the room when you need its facilities and keep the visit practical. Do not treat it as a luggage room, dressing lounge or private place for a long phone call. Fold equipment back as instructed and give priority when another user needs the accessible route.
What to know
An ostomate fixture is not an ordinary sink
The ostomate symbol identifies equipment for cleaning a colostomy or urostomy pouch. It can resemble a low sink or deep basin, but it is not a handwashing basin, laundry tub, drinking fountain or rubbish point.
Use the ordinary hand basin for handwashing. Do not place luggage or a child on specialized equipment, and do not move rails or beds unless their instructions permit it.
What to know
Baby facilities vary by room and by side
A baby-chair symbol means there is a fixed seat for an infant while the adult uses the toilet; a changing-table symbol means something different. Check the weight, age and fastening instructions before use and keep one hand on the child when the equipment requires it.
Do not assume every men’s, women’s or all-gender restroom has the same baby equipment. A station or mall map may identify the appropriate room. Close a fold-down table after use and dispose of diapers only where the facility explicitly accepts them.
What to know
Toilet slippers appear mainly in private-style interiors
A home, ryokan, small restaurant or traditional property may place dedicated slippers just inside the toilet. Change at that threshold, wear them only in the toilet and leave them there before returning to the corridor or tatami room.
Do not expect slippers in an airport, station or other ordinary public restroom. If none are provided, keep your permitted footwear on; do not enter barefoot merely because the room contains a toilet.
What to know
Public access is common but not guaranteed
The industry visitor guide lists airports, stations, accommodation, shops, parks, Shinkansen and some long-distance buses as common toilet locations and says most public facilities provide paper. It also warns that a traveler may need staff permission depending on the facility.
Do not assume every convenience store, café, local train or bus has a customer toilet. Read the sign, buy or check in when required and ask “Toire o tsukatte mo ii desu ka?”—“May I use the toilet?”—rather than walking through staff-only space.
What to know
Cleaning can continue while facilities remain open
Public toilets are serviced frequently, and the industry guide notes that cleaners may continue working while people use the facility. Follow temporary closures, cones and the cleaner’s direction instead of entering a blocked cubicle.
A cleaner’s presence is not permission to photograph or film inside. Protect other users’ privacy, keep belongings under control and move to another facility if the current arrangement is uncomfortable for you.
What to know
Wash your hands and leave the equipment ready
Use the hand basin, soap when available and the provided dryer or paper system. Automatic soap, water and dryer sensors can be separate, so move your hands to the marked zone instead of striking or pulling the unit.
Check that the bowl has cleared, the seat and floor are clean, specialized equipment is folded safely and personal items are with you. Do not wash shoes, clothing, food containers or travel gear in a shared restroom unless a marked fixture explicitly allows it.
What to know
Report a fault before it becomes an overflow
If water rises, the control fails or the bowl does not clear, stop flushing and tell staff. Do not remove a tank lid, unplug a washlet, turn plumbing valves or put your hand near a nozzle in a public or hotel toilet.
Useful phrases are “Nagaremasen”—“It will not flush,” “Koshō shiteimasu”—“It is out of order,” and “Tasukete kudasai”—“Please help me.” Leave a visibly unsafe cubicle and keep others from entering while you contact staff.
If that does not work
Use the fallback.
- If you cannot find the flush, inspect the tank, pipe, wall and remote for the bowl-and-water pictogram.
- If the controls are unclear, skip the washlet and use toilet paper; the spray is optional.
- If you pressed the emergency call by mistake, stay and tell the responder that you are safe.
- If only a squat toilet is available but you cannot use it safely, ask for a Western-style or accessible toilet.
- If the toilet will not clear, stop flushing and report it before the water rises.
- If a shop toilet has no public sign, ask permission before entering.
