Kasaoka Onsen

Kasaoka Onsen is located in Kasaoka City, Okayama Prefecture, on the Seto Inland Sea coast at the base of the Kasaoka Islands — an archipelago of small inhabited islands accessible by ferry, whose traditional island fishing communities, stone-walled hamlets, and quiet rural way of life have been designated as a Slow Life destination promoting sustainable island tourism. The siliceous thermal waters here provide wellness facilities for a coastal city whose island archipelago offers some of the most authentic and peaceful island life experiences in western Japan, far from the tourist infrastructure of more famous Inland Sea destinations. Bathing at Kasaoka Onsen complements an exploration of the city's remarkable island communities, where the combination of mineral spring relaxation and the unhurried pace of traditional Inland Sea island culture creates a restorative experience of genuine western Japanese coastal tranquility.
