9.8/10 Exceptional! (12 reviews)
Our stay was an absolute pleasure, a truly authentic Japanese countryside retreat. Nestled on the outskirts of a small village in Kyushu’s breathtaking rural landscape, the property offers a peaceful and experience. Our traditional Japanese-style room overlooked a beautiful garden, with a stream flowing just beyond it. From the moment we arrived, the staff made us feel welcome and went above and beyond throughout our stay to ensure we were comfortable and relaxed.
We chose to have both breakfast and dinner in our room, though meals can also be taken in the communal dining area. Every dish was beautifully presented and delicious, and the team was happy to accommodate some food restrictions.
The rooms do not have private showers, but the property features four private onsens, each with its own unique character, where you can enjoy a soothing volcanic hot bath followed by a shower in complete privacy. The rooms themselves are spacious, and designed for relaxation, sleeping on comfortable futons that are set up by the team after dinner.
With Mt. Aso and the surrounding parks just a short drive away, this is the perfect base for exploring nature, slowing down and recharging.
