The Empress Bath at Naradanosato Hot Spring sits in Hokuto, Yamanashi Prefecture. Its bicarbonate, alkaline water (pH 8) stays around 40°C, filling an indoor pool and an outdoor rotenburo, with a sauna on site for a relaxing stop amid the surrounding mountains.
Insider tip — Naradanosato Hot Spring Empress Bath occupies a tranquil mountain village in Yamanashi's Hokuto district, where the imperial-grade name signals a long history of distinguished patronage. The bicarbonate water at 40°C is crystal clear and carries a silky softness that leaves skin glowing, a quality Yamanashi locals call bihada no yu or beauty water. Panoramic views of the Southern Alps frame the outdoor pool, while the surrounding Nara meadows bloom with wildflowers from April through June. The facility maintains a ryokan-style calm rarely found in larger onsen resorts.
