At Yamato no Yu, we draw more than 120 liters of hot water per minute directly from the source, and after heating it to just the right temperature, it pours from the spout as drawn. Bath water that overflows from edges of the bath is not reused. Fresh hot water is always being supplied to bath to keep it full. We have also installed a water circulation and filtration system that cleans the water in the bath and keeps it at the perfect temperature. There is no one word to describe this system, but the important points are summarized below.

  • After being warmed to just the right temperature, hot water from the source flows directly into the bath.
  • Hot water that overflows from bath is disposed of, not reused.
  • Hot water in bath itself circulates through a water circulating filtration device, which maintains both the freshness and temperature of the onsen.
