The temple baths
Japanese bathing culture began in Buddhist temples. Their baths were called yuya ("hot water house") and, as they grew, ōyuya. Most were steam baths – mushiburo. At first only priests and the sick could use them; in the Kamakura period (1185–1333) the sick were routinely given access.

From steam to tub
Japan's public baths today, the sentō, are mainly bathhouses with hot pools. Their origin, however, is the steam bath. Like the hammam and the Eastern European banya, the mushiburo shows that steam, sweating and washing go together in many cultures.
In a garden sauna, steam comes from throwing water onto hot stones. How much stone mass and power your heater needs is explained in our guide wood or electric heater.
