In Japan, most houses have a bathtub in their bathroom. The average size allows an adult man to sit with his legs outstretched and soak himself up to his shoulders. The hot water in the tub is used by all the members of the family, so you should wash your body and hair before getting into the tub.
The Japanese not only take a bath at home but also often go to a hot spring resort. Travel with its main purpose being a visit to a hot spring is called onsen ryokô. Some hot spring inns have rotenburo—meaning "open-air bath"—where you can take a bath while enjoying looking at the surrounding scenery. They're very popular because they give you the feeling of being free.
