Aso Hakuun Sanso

Kumamoto Prefecture／Aso City

A natural Onsen accommodation quietly nestled in the vast caldera of Aso Akamizu Onsen Village.

After 10 years, Aso Hakun Sanso has reopened as a Resort Hotel Onsen nestled in the magnificent nature of Mount Aso. From the property, you can enjoy views of the majestic Aso mountains, relax in the Akamizu Onsen known for its skin-beautifying effects, and savor the hotel's delicious cuisine.

  • The property was new...

    The property was new and spotless, and the Room was spacious and comfortable. Thank you for driving us to the station—it was very helpful. Breakfast was delicious as well. Thank you very much.

  • Highly satisfied.

    Nearly 30 years ago, I stayed several times at the old Hakun Sanso before it was rebuilt. I was disappointed when it was demolished, but after seeing an advertisement that it had newly reopened, I decided to stay again for the first time in a long while. The bath area was clean, though I was a bit disappointed there wasn’t an open-air bath. The buffet meals were also delicious. Perhaps because it was the last night of a holiday weekend, there were few guests and I could relax. One small issue: the chairs at the Room table set were too high and uncomfortable to sit on.
