Yunosako Onsen (Koge Buraku Ri, Taiheiraku) is located in Koge, Fukuoka Prefecture. Its sodium-chloride water, at 41°C, feeds an indoor bath, an outdoor rotenburo and a sauna.
Insider tip — Yunosako Onsen Taiheiraku, the great peaceful enjoyment spring of Koge village, serves a rural community in the forested hills of Chikujo District above the Nakatsu agricultural plain. The Koge area of northern Fukuoka is a transitional highland between the Buzen coastal settlements and the Oita volcanic highlands, and the hot spring draws from sedimentary aquifers laid down in the ancient Tertiary sea that once covered northern Kyushu.
