Insider tip — 'Takayama Tennen Onsen Club' in Kimotsuki-cho — home of JAXA's Uchinoura Space Center, Japan's first satellite launch site (Osumi satellite, 1970). This rural Osumi Peninsula town bridges traditional Yamato culture and space-age technology. The natural hot spring club amid Kimotsuki's pristine cedar and broadleaf forests offers grounding after the disorienting proximity of orbital launches from this ancient land.
