Iya Onsen Hot Spring (Cable Car Access)

Iya Onsen sits deep in the Iya Valley in Miyoshi, Tokushima, one of Japan's most remote mountain gorges, and is reached only by a small cable car that descends roughly 170 meters from the ryokan's reception down to the riverside bathhouse. The hot spring itself is a weakly alkaline mineral water long used by valley residents for muscle relief after farming and forestry work, drawn from a source near the Iya River. The open-air rotenburo sits directly on the riverbank, walled in local stone, with views up the gorge toward cedar-forested slopes and the valley's famous vine bridges; an indoor bathing hall with a separate mineral tub is available for those who prefer to skip the cable car ride or bathe after dark. There are no therapists or spa staff in the Western sense; the onsen is staffed by bath attendants who manage water temperature and towel service, and the appeal is the setting and the mineral water rather than a treatment menu. Day-use visitors buy a combined entry and cable car ticket at the reception building above the gorge; walk-ins are accepted, though calling ahead is advised for groups during peak leaf-viewing weekends in autumn, when the single-car lift creates queues. Facilities are limited to the two bathing areas, a small changing room, and a rest area near the upper station; there is no sauna or pool complex. Overnight guests at the attached ryokan get extended access to the lower bath outside standard day-use hours. Because the bathhouse is unroofed on one side and sits at valley-floor level, water can run cold on winter mornings before the first cable car of the day.
