The Washlet: Japan's Gift to Civilization
The Japanese washlet (warm-water bidet toilet seat) is found in over 80% of Japanese households and virtually every hotel, restaurant, and public building. Made primarily by TOTO, INAX, and Panasonic, these toilet seats feature a heated seat, rear wash spray, front wash spray (bidet), adjustable water pressure and temperature, air dryer, and deodorizer. Once you use one, regular toilets feel primitive. The experience is hygienic, comfortable, and far superior to toilet paper alone. Most buttons are labeled with universal icons, though some older models have Japanese-only labels.
Tip: The big red button is always STOP — not flush. If you accidentally hit a spray button, hit the red button immediately. Flush is usually a separate lever or sensor.
Button Guide: What Everything Does
おしり (Oshiri) — rear wash, the primary bidet function. ビデ (Bide) — front wash, positioned differently. 止 (Tome/Stop) — stops all water. 水勢 (Suisei) — water pressure (weak to strong). 温度 (Ondo) — water temperature. 乾燥 (Kansou) — warm air dryer. 流す (Nagasu) — flush (if electronic). 音 (Oto) or ♪ — sound masking (plays flushing sounds to cover bathroom noises). Newer models have motion sensors — the lid opens automatically when you approach and the seat warms. After washing, use the air dryer or a small amount of toilet paper to pat dry.
Squat Toilets and Public Restrooms
Squat toilets still exist in older buildings, parks, and train stations — face the hooded end (the wall). They are perfectly hygienic and many Japanese prefer them for public use (no skin-to-seat contact). In multi-stall restrooms, the Western-style stall is marked with a chair icon. Public restrooms are everywhere in Japan: every station, every konbini, every department store, every park. They are almost always free and remarkably clean. Konbini bathrooms are the most reliable — any 7-Eleven or Lawson restroom will be accessible and maintained hourly.
Toilet Paper, Etiquette, and Quirks
Japanese toilet paper is designed to dissolve quickly — always flush it (never put it in a wastebasket, unlike some Asian countries). Some public restrooms may lack paper — carry a small tissue pack (sold everywhere for ¥100). The 'otohime' (sound princess) device or button plays water sounds to mask bathroom noises — pressing it saves water versus courtesy-flushing. Dual-flush toilets have two buttons: small (小) for liquid waste, large (大) for solid. In homes and ryokan, dedicated toilet slippers sit inside the bathroom door — use them, and absolutely remember to switch back to regular slippers when you leave.
