Ryokan Miyama Sansou  

Tucked into the mountains of Oku-Kurokawa Onsen in Minamioguni, about 5 km from the town center. A traditional ryokan set among thatched-roof cottages with fresh mountain air and big night skies.

The property blends a main building with ten thatched-roof cottages for a total of 18 rooms. Expect a quiet, nature-forward vibe — birds, wind, and a dark-sky canopy perfect for stargazing. Rooms vary by category and include in-room TVs; unwind further in the on-site hot springs and massage room.

On-site restaurant, hot springs (onsen), massage room, guest parking and Wi‑Fi. Elevator access, safe-deposit boxes and limited outdoor lighting to keep the stars visible. Wake up to mountain air and sunsets that paint the valley.

Wi‑Fi is available for guests. Parking and English-speaking staff make short-stay logistics easy.

An on-site restaurant serves creative kaiseki using rice from the ryokan's own fields and pure Aso spring water. Traditional Japanese flavors and seasonally driven presentations are the focus.
