- SANSUI
A one-of-a-kind space where you can immerse yourself in an extraordinary dialogue with nature.
SANSUI is a private rental Hotel nestled on the shores of Lake Kussharo in Akan-Mashu National Park, surrounded by Hokkaido’s magnificent wilderness. In this land where primeval forests and rare flora and fauna have long protected a rich ecosystem, 100% free-flowing natural Onsen water—rich in minerals—soothes both body and mind from deep within. Enjoy a private sauna, a campfire, canoeing or SUP on the lake, or morning yoga on the wooden deck. Experience the feeling of returning to nature as you listen to birdsong and watch the ever-changing scenery of the lake and vast sky throughout the day. The luxury of doing nothing is also a precious moment here. Surrounded by beautiful nature that awakens all five senses, you can spend your time just as you wish.

Introduction of the Accommodation

Location
SANSUI is located in the Akan-Mashu National Park in eastern Hokkaido. Surrounded by extraordinary wilderness where primeval forests and precious ecosystems of flora and fauna have been preserved, it is also easily accessible—about a 1-hour drive from Memanbetsu Airport.

100% Free-Flowing Onsen (Direct from the Source)
We offer both an open-air bath and an indoor bath where you can fully enjoy 100% free-flowing natural Onsen water. The Onsen is so clear it is known as the “Crystal Bath,” with a smooth feel and mineral-rich quality. Soak in the continuously bubbling source while taking in the ever-changing beautiful scenery, and let it gently embrace both body and mind. *Swimwear is required for the open-air bath.*






You can enjoy a HARVIA wood-burning sauna by lighting the stove yourself. “Healing with Heat” while gazing out over the lake offers an exceptional sauna experience. A cold plunge bath is also available, and you may enter the lake as well. Turn this one-of-a-kind experience into a treasured memory. *The cold plunge bath is unavailable from November to March due to freezing conditions. *There is no sauna in the Migi Building.





At the Nukumori building, we offer canoe rentals; at the Migiwa building, we provide a wide selection of rental activity equipment, including canoes, kayaks, SUPs, and bicycles. Please come and experience the rich natural surroundings for yourself. *Please note that equipment may not be available for use depending on weather conditions.*

Projector & Audio System
We have installed a projector and original SANSUI speakers so you can enjoy music and movies as a special moment.
