Shiso, in the inland mountains of central Hyogo Prefecture, is a small forested city set in the valleys of the Ibo River and its tributaries, surrounded by the cedar and hinoki cypress forests of the Chugoku mountain range that create a deeply Japanese rural landscape of wooded ridges and river terrace farming. Shiso Onsen Hyogo draws on sodium and bicarbonate thermal waters from the geothermal resources of the inland Hyogo mountain zone, offering restorative baths in a remote forested setting where the sounds of the Ibo River and the mountain wind create an authentically therapeutic natural spa atmosphere far from the coastal urban centres of Hyogo Prefecture. The Yamasakicho Ibo River cormorant fishing tradition, the Fukusaki Town Folklore Museum from the hometown of Yanagita Kunio the father of Japanese folklore studies, and the forested mountain trails above Shiso create a rewarding hidden spa destination in the Harima highland forests.

Insider tip — Shiso sits in the upper Ibo River valley in inland Hyogo, where bicarbonate springs emerge from crystalline basement rocks of the Chugoku Range. The water has a clean, slightly alkaline character that smooths the skin without the heaviness of chloride baths. Forested hillsides and rice terraces surround the small onsen facilities, offering a genuinely rural atmosphere. Autumn foliage along the river gorge makes this a particularly scenic destination from October through November.
