Oniyama Hotel: Beppu's Largest Open-Air Bath Accommodation

Oniyama Hotel draws its bathing water from Oniyama Jigoku, giving the inn a direct connection to Kannawa’s geothermal landscape. The large open-air bath uses freely flowing water and is the property’s defining feature.

The same local resource shapes the kitchen through jigoku-mushi, Beppu’s method of cooking with geothermal steam. Seasonal Oita courses sit alongside this regional specialty, allowing guests to experience the hot-spring culture through dinner as well as the bath.

The hotel has fifty-seven rooms and a more substantial scale than a small family inn. Renewed interiors and positive food and service feedback make it a balanced choice for travelers who enjoy shared bathing and a full evening meal. Oniyama’s strongest quality is the clear link between its water source, steam cooking and Kannawa setting.
