I’m sorry to keep doing this to you but I have more toilet stories. Well, really just one. The ryokan we are staying in has the most ingenious toilet. Aside from the normal sprays and heated seat found on most toilets, this one has a sink on its tank with a little spicket. So when you flush (press forward for #1, backward for #2 to allow flushing capacity and water in the tank accordingly), the water comes out of the spicket on the top and flows down in to the tank! So you are able to wash your hands (no soap, cold water) in the water coming from the spicket whilst it fills your tank! A nice idea and touch, I think!
