Insider tip — Nakanojō sits in Agatsuma District — Gunma's most concentrated onsen landscape, within 20 km of Shima Onsen (Japan's oldest registered onsen, over 1,200 years), Manza Onsen (Japan's highest onsen resort at 1,800m), and Kusatsu (arguably Japan's finest onsen town). Shiriyaki Onsen 'Kawaburo' (river room) draws sulfurous volcanic water from the Shima/Agatsuma geothermal zone; 'kawaburo' suggests a riverside bathing room where the sound of flowing water accompanies the mineral soak.
