Insider tip — 'Yunoyamakan' (湯の山館 — hot spring mountain inn) at Iriki Onsen in Satsumasendai. The Iriki Onsen has been known since the Satsuma Domain era, when its thermal waters served the domain's agricultural and forestry workers in the Sendai River highlands. Satsumasendai city contains both coastal fishing communities and highland farming villages — the 'mountain inn' of the spring name anchors this bath in the highland character of Iriki's forested ridges above the Sendai River.
