Young Blonde Girl Undresses Her White Top And Panties On The Chair In The Public Bath Area

The origin of Japanese bathing is Misogi, ritual purification with water. After Japan imported Buddhist culture, many temples had saunas, which were available for anyone to use for free.
In the Heian period, houses of prominent families, such as the families of court nobles or samurai, had baths. The bath had lost its religious significance and instead became leisure. Misogi became Gyōzui, to bathe in a shallow wooden tub.
In the 17th century, the first European visitors to Japan recorded the habit of daily baths in sexually mixed groups. Before the mid-19th century, when Western influence increased, nude communal bathing for men, women, and children at the local unisex public bath, or sentō, was a daily fact of life.
In contemporary times, many administrative regions require public baths to have separate facilities for males and females. Public baths using water from onsen (hot springs) are particularly popular. Towns with hot springs are destination resorts, which are visited daily by the locals and people from other, neighboring towns.
