Insider tip — 'Shigehisa Onsen; Kazoku Furo' (family bath) in Kokubu district, Kirishima city — named for the Shigehisa family or locality. The family bath (kazoku furo, kazoku buro) — a private room bookable for families or groups — became essential in post-war Japan for families seeking the onsen experience without communal bathing. Kirishima's geothermal system, fed by the Shinmoedake and Nakadake volcanoes' magma chamber, provides warm spring water throughout the Kokubu lowlands.
