Overview (history, characteristics, attractions)
Umi Jigoku (Sea Hell) is one of the tourist hells in the Kannawa Onsen area of Beppu City, Oita Prefecture, and is a representative spot on the Beppu Hell Tour. As its name suggests, it is characterized by a large, deep cobalt blue pool of hot water that evokes the sea, and the sight of the hot water gushing out, the rising steam, and the unique color make a strong impression. It has been known as a tourist destination since the Meiji period, and the surrounding area is home to greenhouses displaying tropical plants, souvenir shops, and restaurants that use hell steaming.
Highlights
