22. The bathroom has a heating unit that works like a dryer
While most Japanese bathrooms are built to keep the moisture in, have you ever wonder how could they prevent it from going moldy? Surprise, aside from its main feature as a bathroom, they also work as a drying unit. With only one button, a warm fan that will blow dry the room will be activated. You just need to wait a couple of hours, then the whole area will be completely dry. During the harsh winter, Japanese people will choose to hand their clothes in this place instead of outside. By drying the room and clothes at the same time, you are saving a lot of electricity.
