While toilet paper is widely available and used in Japan, the country is world-famous for its high-tech alternative: the Washlet or "Electronic Bidet." These integrated toilet systems, perfected by companies like TOTO, use a retractable wand to provide a high-fidelity warm-water spray for cleaning. The controls typically allow the user to adjust the water temperature, pressure, and position of the spray. Many modern Japanese toilets also feature heated seats, a "deodorizer" function, and a "sound princess" (Otohime) which plays the sound of rushing water to provide privacy. After washing, many units also have a built-in warm-air dryer, which significantly reduces the need for large amounts of toilet paper. In 2026, these toilets are the standard in almost all Japanese hotels, department stores, and even public train stations. While travelers might still use a small amount of paper to "pat dry," the bidet system is considered more hygienic and environmentally friendly. For the uninitiated, the experience is a cornerstone of Japanese hospitality (Omotenashi), turning a basic necessity into a customized, high-comfort experience.
