Insider tip — 'Shikisai' (四季彩 — four-seasons colours) at Tsunagi Onsen in Tsunagi-cho, a small town on the southern Kumamoto coast. Tsunagi is known for the extraordinary Tsuruta Goryo Museum — its art is literally painted onto the mountain rock face, the largest outdoor art work of its kind in Japan. 'Four seasons colours' captures both the gallery's seasonal exhibitions and the changing light on the Yatsushiro Sea visible from the onsen's coastal position.
