Kamisato Onsen, part of the Kamisato Fureai Koryu exchange centre in Assabu on the island of Hokkaido, offers sodium-chloride thermal water at 40°C, an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Assabu-cho (厚沢部町) on the Oshima Peninsula of southern Hokkaido is a small agricultural community in the forested interior, not far from the Seikan Tunnel — for many years the world's longest undersea railway tunnel, connecting Hokkaido to Honshu since 1988. The Kamisato Onsen Fureai Koryu Center is a classic rural Hokkaido community facility: unpretentious, welcoming, and deeply embedded in the fabric of a quiet agricultural town far from tourist itineraries.
