Yufudake Ichibo no Yado Kirara

Ichibo no Yado Kirara sits on a low hill just outside the busy part of Yufuin, close enough to town but far enough to keep things quiet. The draw is the view: every guest room looks out toward Mount Yufu, and the rooms themselves each come with a half-open-air bath fed by 100% source hot-spring water, so soaking and watching the mountain happen in the same spot, ideally on a clear morning.

This is a stay-overnight property rather than a drop-in day spa — it's classified here as an onsen and hotel spa with overnight stay as part of the experience, aimed at adults and couples. Rooms are done in a Japanese-modern style, and meals are a kaiseki-style set menu built around Oita ingredients: seafood from the Bungo Channel (including Seki-aji and Seki-saba depending on season), Oita wagyu, and local mountain vegetables. Plans change with the seasons, with options built around specific ingredients like Oita wagyu steak or shabu-shabu, or seasonal sashimi presentations of Seki-aji and Seki-saba.

Booking is through the property's own reservation system or by phone, and a reservation is required before arrival — this isn't a walk-in soak. Pricing sits in the upscale range for the area, reflecting the private in-room baths and the kaiseki dinners, though the site lists several seasonal plans rather than one fixed rate. Specific hours for bath use, check-in and check-out aren't listed, so it's worth confirming timing directly with the front desk when booking.
