A spectacular view overlooking the Pacific Ocean, and a soak in a globally rare iodine-rich spring
Hokkaido Taiki Town
"Bansei Onsen" is a bath facility located along the coast in Taiki, Hokkaido. Its biggest draw is its rare brownish iodine-rich natural hot spring, one of the few of its kind in the world, which is expected to offer strong antibacterial and warming effects as well as skin-beautifying benefits. The sauna is a full-fledged setup that allows self-löyly, and its calm atmosphere is enhanced by radio playing in a quiet, TV-free space. After cooling down in the cold bath filled with groundwater, you can enjoy an outdoor bath while listening to the sound of the Pacific waves, surrounded by an overwhelming sense of openness. The reasonable pricing, which includes a towel set, is another attraction, letting you refresh to your heart's content.
