- Water handling
- From June through October, the open-air bath uses 100% source flow. From November through May, the spring is heated directly through a heat exchanger without adding water. The hinoki and rock baths use a partial-flow system: fresh spring water is added while water overflows, alongside circulation and filtration. These conditions differ by bath; the facility is not described as entirely source-flowing.
