Kannawa Onsen Ichinoide in Beppu, Oita Prefecture, sits within the most thermally intense onsen city in the world, where the ground steams from over two thousand spring vents producing more geothermal water than any other onsen district in Japan and contributing to the surreal landscape of steam rising from streets, gardens, and hillsides that defines Beppu's unforgettable visual character. The siliceous spring water of the Kannawa district, one of Beppu's eight famous hot spring zones, is particularly celebrated for its bijin no yu skin-beautifying properties, flowing from the same volcanic geology that has made Beppu the preeminent thermal destination in Asia for over a century of modern tourism. The famous Jigoku, or Hell, springs of Kannawa, where brilliantly coloured pools of superheated, mineral-saturated water boil dramatically in a park environment, represent the theatrical extreme of Beppu's extraordinary geothermal show.
Insider tip — Kannawa is Beppu's most atmospheric onsen district, where white steam perpetually rises from street vents giving the entire neighborhood an otherworldly appearance. The Ichinoide facility draws water from the same volcanic field that supplies the famous Beppu Jigoku hells, with sulfurous mineral water at around 44°C flowing into stone-clad communal baths. The district's mud baths and steam chambers are unique even within Japan's extensive onsen culture. Arriving by local bus through steam-shrouded streets lined with wooden bathhouses perfectly captures what has made Beppu the country's leading thermal city.
