The feature set commonly found on washlets are anus washing, bidet washing, seat warming, and deodorization.
Japanese toilets are well-known in popular culture and often parodied in amusing ways in comedic works set in Japan.
and is used both for the toilet itself and for the room where it is located.
Similarly to the word anime, toire is often mistakenly identified as a French language loan word due to its French-sounding ending.
The latter is easier to use for men to urinate while standing, but both types can be used for this purpose.
There is also no difference for defecation or squatting urination.
All other fixtures, such as the water tank, piping, and flushing mechanism, may be identical to those of a Western toilet.
Flushing causes water to push the waste matter from the trough into a collecting reservoir which is then emptied, with the waste carried off into the sewer system.
In Japan, these bidets are commonly called washlets, a brand name of Toto Ltd., and include many advanced features rarely seen outside of Asia.The waterless trough minimizes the risk of splash-back of water during defecation.However, because the products of excretion sit exposed to the open air until flushed away, they commonly produce much stronger odors than they would when submerged as in a Western toilet, an effect that is often quite noticeable in or anywhere near a Japanese restroom.The flush is often operated in the same manner as a Western toilet, though some have pull handles or pedals instead.Many Japanese toilets have two kinds of flush: "small" (小) and "large" (大). The former is for urine (in Japanese, literally "small excretion") and the latter for feces ("large excretion").The user squats over the toilet, facing the hemispherical hood, i.e., the wall in the back of the toilet in the picture seen on the right.A shallow trough collects the waste, instead of a large water-filled bowl as in a Western toilet.Another common strategy employed by foreigners to avoid any potentially embarrassing accidents while defecating is to strip completely from the waist down and hang the garments on a hook before assuming the position.One advantage of squat toilets is that they are very easy to clean.The toilet itself—that is, the bowl or in-floor receptacle, the water tank, et cetera—is called benki (便器). A potty, either for small children or for the elderly or infirm, is called omaru (sometimes written 御虎子).The Japan Toilet Association celebrates an unofficial Toilet Day on November 10, because in Japan the numbers 11/10 (for the month and the day) can be read as ii-to(ire), which also means "Good Toilet".
