Onsen no Sato, part of the Yamaga Donguri Mura complex in Yamaga, Kumamoto, draws sodium-chloride water at 41°C. An indoor bath, an outdoor rotenburo and a sauna round out this thermal stop.
Insider tip — Yamaga Donguri Mura, the acorn village spring, combines forest nature park experiences with hot spring bathing at the edge of the oak and cedar highlands above Yamaga City. The acorn harvest from the surrounding Yamaga forests each autumn sustains the wild boar and deer that are hunted by local mountain communities in a traditional akatsu-ryō hunting practice that has been maintained since the Heian period in these Kumamoto highlands.
