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.
