  • We stayed here for a long-awaited couple's trip. The staff provided detailed explanations, and the free drinks were plentiful. The meals were also delicious. The room had an Onsen, so we could enjoy it anytime, which made us very satisfied. We would love to stay here again!

  • I stayed in a room for one person. It is located very close to Kagoshima Airport by car. Nestled in the mountains, it is very quiet, but early mornings and nights in winter can be cold. The Onsen in the private room bath is free-flowing, so you can enjoy it anytime. Next time, I would like to stay in a room with an open-air bath or a glamping room.
