Attached to a sports center, Mizuho Onsen in Tokorozawa, Saitama, uses sodium-chloride water at 41°C. An indoor bath, an outdoor rotenburo and a sauna are on offer.
Insider tip — Mizuho Onsen serves the Tokorozawa Sports Center complex in Saitama Prefecture, the city that gave Japan its first aerodrome — the Tokorozawa Military Airfield established in 1911 was Japan first permanent aviation facility. Tokorozawa is also the home of the Seibu Lions baseball team and the Seibu railroad empire whose development of the Musashino plateau transformed this upland from silk-farming countryside into the suburban entertainment landscape anchored by Tokorozawa Sakura Town — the largest pop culture complex in Asia.
