Gyozenji Onsen; Umi no Yu / Yama no Yu is located in Hakusan, Ishikawa Prefecture. The sodium-chloride water flows at 41°C. Two bathing settings — sea and mountain — are offered, alongside an indoor bath, an outdoor rotenburo bath and a sauna.
Insider tip — Gyozenji Onsen offers two contrasting soaking experiences — Umi no Yu (sea bath) and Yama no Yu (mountain bath) — serving Hakusan City at the transition zone between the Japan Sea coast and the sacred Hakusan volcanic massif. The dual-bath concept mirrors the landscape itself: to the west the Sea of Japan where the Gyozenji coastal temple once guided fishing communities, to the east the white-capped summit of Hakusan volcano at 2,702 metres whose pilgrimage tradition dates to the Buddhist monk Taicho Daishi in 717 CE.
