An authentic sauna featuring sauna stones mixed with Mt. Fuji lava and an automatic löyly system that sprays natural Mt. Fuji water onto the stones. The subdued interior, with indirect lighting and wooden finishes, is designed to stimulate both sight and heat simultaneously.

Uses natural Mt. Fuji water (vanadium water) pumped up from 150m underground, allowing you to pleasantly cool your body after heating it in the sauna. Because it is natural water, its temperature varies by season. You can cool down in an atmospheric outdoor area immediately after the sauna.
