Hokkaido
10 onsen areas

Niseko Onsen-kyo

Central Hokkaido onsen by the Tokachi River, famous for its rare 'moor' springs — humic-acid waters drawn from ancient peat-bog deposits, prized for their skin-softening properties.
Kawayu Onsen
Strongly acidic sulfur onsen in eastern Hokkaido, in Akan-Mashū National Park near Mount Iō. Hot enough at the source to flow through open canals in the town center.
