Soak your stresses and strains away at this popular hot spring spa in the woods

Akigawa Keikoku Seoto-no-Yu Spa is in Akiruno, to the west of Tokyo. It's a simple facility, and its elegant design blends well with the beautiful natural surroundings of the Akigawa Valley. The onsen (hot spring) features a single indoor bath, a sauna, and a stone-ringed outdoor bath with a view of the forest. Seoto-no-Yu's alkaline water is great for the skin, leaving it feeling slightly slippery. The onsen also has a traditional restaurant featuring local fare and an attached shop selling regional goods.
