Takamagahara Onsen, in Toyama city, Toyama Prefecture, channels mildly alkaline (pH 8) thermal bicarbonate water at 41°C. Facilities include an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — 'Takamagahara' (Plain of High Heaven, the celestial realm of the Shinto gods) is a grandly named onsen in the Toyama mountains, near the legendary Tateyama Kurobe Alpine route. The name evokes the divine character of the surrounding Northern Alps. A fitting place for contemplation after a day on the mountain.
