Insider tip — 'Sekibira Onsen' in the Makizono volcanic zone of Kirishima city, at higher elevation approaching the Kirishima mountain chain's active peaks. 'Sekibira' (関平 — checkpoint plain) references the mountain checkpoint that historically controlled access to the sacred volcanic summits. The sulfurous waters here are in the classic Kirishima tradition — powerful, mineral-dense, steaming with volcanic energy drawn from the magma system beneath active Shinmoedake (eruptions 2010-2011, 2018).
