Shibaseki Onsen

Shibaseki Onsen in Beppu, Oita Prefecture, occupies one of the eight distinct thermal spring zones of the Beppu Hatto system, the most prolific geothermal network in Japan, where the volcanic energy of the Aso-Kuju volcanic arc produces an astonishing variety of spring types including simple, acidic, chloride, radium, sulphur, and sodium bicarbonate waters within a single urban area. The siliceous spring water at Shibaseki provides smooth, skin-softening baths in a neighbourhood that retains more of the intimate, working-class onsen character of pre-tourism Beppu than the resort-focused zones closer to the waterfront. The extraordinary thermal diversity of Beppu, matched by an equally diverse food culture anchored in local seafood from Beppu Bay and the volcanic cuisine of steamed dishes prepared over natural geothermal vents, makes the city one of Japan's most complete sensory destinations.
