How to Use a Japanese Toilet — Everything First-Time Visitors Need to Know
← Back to Culture, Etiquette & Special Situations
The first time you sit down on a Japanese toilet and the seat is warm, you'll either find it deeply unsettling or immediately understand why Japan has a global reputation for bathroom technology. Japanese toilets — specifically the high-tech washlet models found in most hotels, restaurants, and homes — have controls that range from the obvious to the genuinely confusing. Here's what everything does, which buttons to avoid, and what to expect in different types of facilities.
The two types of toilets you'll encounter
Western-style washlet (ウォシュレット): a standard western toilet seat fitted with a bidet panel — either a side panel on the toilet itself or a wall-mounted panel nearby. Heated seat, water spray functions, and often a dryer. This is what you'll find in virtually every hotel, modern restaurant, convenience store, and private home in Japan. The technology ranges from basic (two buttons) to elaborate (ten or more functions).
Japanese squat toilet (和式, washiki): a porcelain trough set into the floor, used by squatting. Still found in some older public facilities, parks, and traditional buildings. Less common than it used to be, but you'll encounter one eventually. You squat facing the hood end (the raised end with the curved shield). There is no panel, no buttons, and no heated seat.
The washlet control panel — what each button does
Control panels vary by manufacturer (TOTO, INAX/LIXIL, Panasonic are the main brands) but the Japan Sanitary Equipment Industry Association (JSIA) standardized washlet pictograms across all major manufacturers in 2017 — meaning the same icons appear on every brand's panels. Learn them once and you'll recognize them in any bathroom in Japan.
おしり / 後洗浄 (Oshiri / rear wash): bidet spray aimed at the rear. The most commonly used function. Usually represented by a person symbol with a water arc aimed at the back. Press once to start, press again or press stop (止) to end.
ビデ (Bidet / front wash): bidet spray aimed at the front. Labeled "bidet" or with a female symbol and water arc. Press once to start, stop to end.
止 (Tomeru / stop): stops the water. Usually the largest or most prominent button. Press this if you've accidentally started a function.
流す / 大 / 小 (Nagasu / flush / large / small): flush controls. 大 (dai, large) is a full flush. 小 (sho, small) is a half flush for liquid waste. 流す just means "flush" when there's only one option.
おと / 音姫 (Oto / Otohime / sound): plays a flushing sound to mask bathroom noise. Common in public facilities. Not a flush — press the actual flush button separately.
乾燥 (Kanso / dry): warm air dryer directed at the rear. Works but slowly — most people use toilet paper to supplement.
温度 / 水勢 (Ondo / Suisei): temperature and water pressure adjustments. Usually + and – buttons near the main functions.
脱臭 (Dasshu / deodorizer): activates a built-in air filter. On automatically on some models when you sit down.
The button you should not press accidentally
The water spray functions (oshiri, bidet) activate immediately when pressed and produce a meaningful amount of water aimed at you. If you're not seated when this happens, or if you press it expecting a flush, the result is unpleasant and wet. The lesson: identify the flush button before pressing anything else. The flush is usually the largest button, often physically separate from the bidet panel, or mounted on the wall or tank behind you.
In facilities where the panel is wall-mounted to the side of the toilet, the flush is sometimes on the tank behind rather than on the panel — the panel controls bidet functions only, and the tank lever or button handles flushing separately.
Finding a toilet in Japan
Japan has an unusually high density of clean, accessible public toilets — one of the most consistently noted positive surprises for first-time visitors.
Google Maps tip: searching in Japanese finds more results than English when looking for toilets urgently. Search 公衆トイレ (koushuu toire, public toilet) or 多機能トイレ (takinou toire, multipurpose toilet with accessibility features) to find nearby options faster than searching "public toilet" in English.
Convenience stores: all major chains (7-Eleven, Lawson, FamilyMart) have toilets available to customers and to the general public in most locations. These are consistently clean and often feature washlets. The most reliable option in any urban area.
Train stations: all major stations have public toilets, usually well-maintained. JR and subway stations in Tokyo and Osaka have washlets in most facilities as of 2024–2026 upgrades.
Department stores (デパート) and shopping malls: excellent public toilets, often with powder rooms and full washlet setups. Isetan, Takashimaya, and similar department stores have some of the best publicly accessible restrooms in each city.
Parks and temples: variable quality. Major tourist sites (Senso-ji, Fushimi Inari) have maintained public toilets near the main areas. Smaller parks may have older squat-style facilities.
The Tokyo Toilet Project: a public art initiative that replaced 17 public toilets in Shibuya with architecturally designed facilities by notable designers (including Tadao Ando and Fumihiro Maki). The project gained global attention after featuring in the 2023 film Perfect Days. The transparent-wall facilities (walls turn opaque when locked) are worth visiting — practical note: after locking the door, wait a few seconds and confirm the walls have fully turned opaque before proceeding. Occasional technical delays or glitches mean the glass can take longer than expected to respond, and some travelers have reported the walls not fully opaquing. Confirm before assuming privacy.
How to use a squat toilet
If you encounter a squat toilet, the technique is straightforward:
Face the hood end (the raised, curved end — not the drain end). Squat down with your feet on the foot pads on either side. Keep your weight on your heels or hold the grab bar if one is present. Most squat toilets have a flush handle or button at the back near the hood. Standard toilet paper is provided at the side.
If squatting is physically difficult, look for a Western-style toilet in the same facility — larger public restrooms in Japan typically offer both types, and the Western-style stall is sometimes marked with a wheelchair or "洋式" (yoshiki) sign.
Toilet paper and waste disposal
Japanese toilet paper is designed to be flushed — it's made to dissolve in the plumbing system. Flush used toilet paper. This is different from many countries in Asia and parts of Europe where a waste bin is provided and paper shouldn't be flushed.
One exception: some older rural facilities or traditional buildings have signage asking you to dispose of paper in the bin rather than flushing. Follow the posted signs if they're present. In the absence of any sign, flush normally.
Sanitary products and wet wipes should go in the bin, not flushed — this applies universally regardless of facility type. Importantly: even if a package of wet wipes says "flushable," do not flush them in Japan. Japanese plumbing — particularly in older buildings — clogs easily from wet wipes regardless of what the packaging claims. Use the bin.
What the "sound" button is for
The Otohime (音姫, "sound princess") button, found in most female restrooms and many general restrooms in Japan, plays a recorded flushing sound when pressed. It exists because Japanese bathroom etiquette traditionally involves masking audible sounds for the privacy and comfort of others — many visitors (and Japanese users) would continuously flush the toilet to mask noise, wasting significant water. The Otohime provides the same social function without the water waste. Press it once when you sit down if desired; it runs for a set duration (usually 20–30 seconds) and stops automatically.
Practical tips for navigating Japanese bathrooms
Remove shoes before entering a ryokan bathroom — separate toilet slippers are often provided at the toilet room entrance in traditional accommodations. Don't wear the toilet slippers outside the toilet room (a common mistake noted with good humor by ryokan staff everywhere).
In smaller restaurants and traditional establishments, the toilet may be in a separate small room rather than a full bathroom — look for the 手洗い (tearai, "hand washing") or トイレ (toire) signs. Toilets and the hand-washing sink are sometimes in separate spaces.
Public toilet stalls in Japan lock with a turn latch (ひねる, hineru) or a slide bolt. The occupied/vacant indicator on the outside shows 赤 (red/occupied) or 緑 (green/vacant). If all indicators show occupied, wait — the stall is in use, not broken.
