Ikesu Onsen is located in Tsushima, Aichi Prefecture. Its thermal sodium-chloride water reaches 40°C, with an indoor bath, outdoor rotenburo and sauna.
Insider tip — Tsushima city in western Aichi (not to be confused with the island between Japan and Korea) hosts one of Japan's most spectacular water festivals — the Owari Tsushima Tenjin Matsuri (夏祭), held each July on the Tenno River, where five lantern-boats drifting by night create one of Japan's most ethereal festival scenes. Ikesu ('fish pond') Onsen draws on the city's aquatic heritage; Tsushima was historically a major river port in the Nobi Plain's transportation network.
