Sentō
Before entering, visitors take off their shoes and put them in shoe lockers.  At sentō in Japan today, it is not good manners to clean one's body in the bathtub.  Bathers must shower before getting in the water.  This keeps dirt, sweat and other things from making the water dirty.  Many sentō provide soap and towels.  Bathers sit on a stool in the shower.  The bathers must not wear any clothes or swimsuits in the sentō.  Bathers may use towels at the sentō or bring their own, but the towel must not go in the water.  Bathers put the towels on their heads instead.  People with long hair tie it up so it does not get in the water.
