Mori no Onsenkan (Alza Oze no Sato) sits at the gateway to Oze National Park, in Hinoemata village, Fukushima Prefecture, Japan. Its sulfurous water emerges at around 43°C and feeds an indoor bath, an outdoor rotenburo and a sauna, amid a mountain setting.
Insider tip — At the gateway to Oze National Park — Japan's largest highland marsh, a vast wetland at 1,400 meters altitude blanketed with golden lysichiton skunk-cabbage in spring — Mori no Onsenkan provides essential pre- and post-trekking thermal recovery; the sulfurous mountain spring and the primordial bog landscape of Oze create one of Tohoku's most immersive wilderness experiences.
