Unofficial Toilet Day in Japan

The Japan Toilet Association celebrates an unofficial Toilet Day on November 10, because in Japan the numbers 11/10 (for the month and day) can be read ii-to(ire), which also means 'good toilet'.

There are three types of toilets in Japan. The oldest toilet, similar to a Turkish plate, is scarce today. After World War II, Western-type flush toilets became common. Today, toilets in Japan are more elaborate than those commonly found in other developed nations. The current status of Western-style toilets in Japan is the bidet toilet, which, as of March 2016, is installed in 81% of Japanese households, and are used in hotels and supermarkets. In Japan, these bidets are commonly referred to as Washlets (ウォシュレット), produced in particular by the TOTO brand, and include many advanced features. The set of features commonly found in washlets are anal hygiene, bidet flushing, seat heating and deodorization. Japanese toilets are well known in popular culture and are often parodied in comedy plays set in Japan.
