Apparently all Japanese toilets will have the new standard symbols as of this year, and the hope is that they will be accepted internationally. © Japan Sanitary Equipment Industry Association Apparently the buttons stand for (starting top left) large flush, small flush, toilet lid up/down, toilet seat up/down, stop, rear spray, bidet, and of course hot air. Some think these are self-explanatory; I am not so sure, and find the rear spray and bidet symbols confusing. Lloyd Alter/ Toto Washlet controls/CC BY 2.0 I have a fancy bidet toilet (and you should too) with people in profile for both spray symbols, which makes a lot more sense than the rear bum view for one and a side view for another. But no matter, at least there is now a standard, so that anyone anywhere will know what buttons to push, even in America.
