Hot Springs (Onsen)


With 150 tons of hot spring waters bubbling up from 2,000 meters below ground, Heiwajima Hot Springs is one of the largest natural hot spring facilities in Tokyo. This hot spring water will leave your skin moist and smooth. The sodium-chloride spring water forms a thin layer over your skin, preventing evaporation and keeping your skin moist.

Viewing Spa

Soak in highly-carbonated hot water while enjoying sports on a big-screen TV. The carbonation helps open small blood vessels, improving metabolism. Or sit in a Japanese-style hot stone spa. Feel the different effects of a variety of stones, while totally unwinding in a relaxed atmosphere.

Large Natural Hot Spring Bathrooms

In addition to the main natural hot spring baths, we have a variety of baths from Jacuzzi-style to reclining. Perspiring in these baths helps you wind down and has many health benefits. Enjoy a resort-like open atmosphere without leaving the city.
