Japan's reputation for exceptional public restrooms is no exaggeration. From rural roadside stations to urban parks, Japanese toilet facilities set a standard that few countries come close to matching. Here is what makes them so special.
Technology
The Japanese toilet industry, led by TOTO and Lixil, has developed bidet toilet seats (washlets) that include: heated seats, warm water bidet functions, air drying, deodorizing, sound masking (for privacy), automatic lids and flushing, and in some models, health monitoring sensors. These are not luxury items in Japan — they are standard in most homes and public facilities.
The Tokyo Toilet Project
In 2020, The Nippon Foundation launched the Tokyo Toilet Project, commissioning 17 world-class public restrooms across the Shibuya neighborhood. Designs include a transparent building by architect Shigeru Ban that turns opaque when locked, a restroom designed as a forest mushroom, and a cylindrical black structure that resembles a luxury spa. The project aimed to transform public restrooms from necessary evils to neighborhood amenities.
Cultural Attitudes
Japanese cultural values around cleanliness (清潔, seiketsu) are deeply embedded. Many Japanese people wear slippers to avoid tracking bathroom floor contamination into the rest of the home, a practice that extends to public facility respect. This collective commitment to shared space cleanliness is a core reason for Japan's superior facilities.
Roadside Stations (Michi-no-Eki)
Japan's network of Michi-no-eki (roadside stations) along national highways are public rest stops with consistent, excellent restroom facilities. They are staffed, cleaned regularly, and often include restaurants, local produce markets and tourist information. The 1,000+ locations across Japan make road trips remarkably convenient.
Public Transit Integration
Japan's train stations are among the cleanest transit facilities in the world. Even small rural stations have clean restrooms maintained by station staff. The JR Pass covers entry to stations with facilities, making these accessible to tourists as well.
What Can the US Learn?
The Tokyo Toilet Project's design-forward approach — treating public restrooms as architecture worth investing in rather than infrastructure to minimize — offers a model. Portland, Oregon's "Portland Loo" (a simple, durable, graffiti-resistant open-slatted single-occupancy design) is the closest US equivalent, with dozens now installed in cities across North America.
