I have experienced two types of toilets while here–the washiki and the washlet. The washiki is the traditional Japanese squat type toilet, named for the
position one assumes to use it, squatting down facing the hooded end of a usually porcelain trough. The washiki is considered more hygienic and wastes less water than a Western toilet, but using one can pose several problems–missing the trough altogether, splattering yourself or falling in the trough.
At the other extreme is the washlet which looks very much like a standard Western toilet. However the add-ons are positively Star Trek-esque. Washlets come with a heated seat, bidet with buttons for front or back spray, controls for temperature and jet power, as well as a dryer. There is also an “etiquette” button that provides flushing sounds to cover up any straining, groaning or splashing noises you may make.
What fun to use the bathroom in Japan!
