Japanese household bathrooms are very different from what you might find in a typical American home. They are far more multi-functional and high-tech. For example, the bathroom is divided into three sections: there's a shower/bath area and a toilet area, which are separately accessible from a sink and vanity area. Consequently, three people can use the same bathroom at the same time!
The shower and bath area is a thing of wonder. There's a deep bathtub that is heated continuously with controls that can be activated from different parts of the house. I want one of those!
In this video, a young girl shows how the different parts of the bathroom function. It's part of a series of videos in which she introduces Westerners to Japanese bedrooms, toilets, and kids' homework, among other aspects of modern Japanese life.
