Insider tip — 'Mikazuki no Taki Onsen' (三日月の滝温泉 — crescent moon waterfall spring) in Kusu-machi, Oita. A waterfall in a crescent shape — perhaps a curved cascade over volcanic basalt — gave this spring its evocative name. The combination of waterfall sound and thermal water in the forested Yamakuni River valley creates one of Japan's most sensory onsen experiences. The crescent moon is a symbol of change and transience — apt for a spring where the river's constant flow meets the earth's eternal heat.
