Yunomine onsen (night/day) (Patreon)

"Yunomine is a quaint little collection of inns tucked into a small valley deep in the heart of the sacred mountains of Kumano. The waters here are said to change color seven times over the course of a day. Yunomine Onsen was discovered about 1,800 years ago, and it is thought to be one of the oldest hot springs in Japan."Yunomine Onsen – Tanabe City Kumano Tourism Bureau (tb-kumano.jp)

わたしはここの温泉のことを地球の臍と呼んでいます。心の中で。
