Myogo Onsen Ume no Yu, in Shinshiro, Aichi Prefecture, offers sodium-chloride thermal water at 40°C. It has an indoor bath, an outdoor bath (rotenburo) and a sauna.
Insider tip — Shinshiro anchors the Oku-Mikawa highlands of eastern Aichi — a forested mountain zone of cedar valleys, the Toyone River gorge, and scattered traditional hamlets far from the Nagoya-Osaka corridor. Ume no Yu (Plum Blossom Bath) is fragrant with plum associations in late February when the surrounding hillsides bloom. The region's clear mountain air and thermal waters make it a restorative contrast to the industrial heartland just an hour's drive west.
