Toilets are pretty advanced in Japan, as I've mentioned before. They will sing to you, they will wash your butt, or your front-butt, if you prefer, and sometimes they are a video game and you win if you hit the right targets with enough force.
But sometimes they are just downright practical, like the one pictured here. In order to save water and space, I think. The sink is attached and only activates itself when you flush. Which, for the anxious Minnesotan(!) only creates the following stresses:
2) is the water dirty?!
4) like, is it recycled poop-water?
5) it's attached to the toilet...
Why is life so hard sometimes?
