Japan lacks toilets, but don't fear, what they lack in the "toil" section they make up in the "wash" section. The Washlet is an amazing Machine. Yes, i said Machine.
I want you to notice a few things. First the black computer panel on the wall. Input your settings here. Want a warm seat.....push a button. Want to wash your bum?....choose two different kinds of sprays and change the nozzle pressure setting with this panel. Then notice the full page of directions the toilet. (sorry, the Washlet). DIRECTIONS! ahh, i just want to go to the bathroom. What if you really can't hold it long enough to read it all. Heck i cant even read it, what if im not going the bathroom correctly.
I also want to direct your attention to the power cord. WHAT?! Why a power cord? Well that powers the seperate control panel on the side of the Washlet. That controls some other settings. Im too afraid to push it. (and i love to push buttons on machines, so this is agonizing...i will push them one day).
And finally notice the most clever part of this Machine. On the top of the Washlet is a sink where you wash your hands with the water that will go into the tank awaiting the next flush. I find this smart and amazing. But it does make it hard to not drip on the ground when you go to dry your hands, so correctly identifying "yellow" drops from "clear" drops on the floor is rather hard.
