Introduction of the Accommodation

An example of a Room

Room

The guest rooms at Tenka Sansou, connected by a corridor from the lobby, are all detached houses. There are two types of rooms: a Japanese-style room with 10 tatami + 8 tatami and a Japanese-Western style room with 2 double beds and an 8-tatami Japanese-style room. Both are spacious with two adjoining rooms. In 2012, terraces were opened in all rooms to allow guests to experience the rich nature of Aso and Minamioguni.

Meal

At Tenka Sanso, we take pride in using delicious seasonal ingredients sourced locally. Enjoy freshly picked vegetables delivered every morning from our partner farms, our homegrown rice, and Kagoshima's premium black Wagyu beef raised in the grandeur of nature—ingredients you can only savor here.

Onsen example
Onsen

Three private onsen baths located at the highest point of Tenka Sansou. Enjoy the magnificent nature of Aso and Minamioguni from within the baths. The private baths at Tenka Sansou do not require a Reservation. If the bath is vacant, you may use it freely as many times as you like. Take your time to relax and enjoy the natural onsen and scenic views.
