Insider tip — 'Fureai Onsen Center' at Kokubu Shimin Pool Koen in Kokubu district, Kirishima city — the urban heart of the former Kokubu city, which merged to form Kirishima city in 2005. Kirishima city encompasses both the flat coastal Kokubu plain and the volcanic Kirishima mountain range that towers above it. The community pool and onsen complex here serves the urban population of this dramatically situated city between active volcano and Kagoshima Bay.
