A walkthrough of “Haru no Umi” (春の海), Suite #357, a Maisonette-style unit with 97m² of indoor space and the top category room at Tokachigawa Onsen Sanyoan (十勝川温泉三余庵), a luxury Onsen (hot springs) ryokan in Tokachigawa, Hokkaido. It’s located on the banks of the Tokachi River, and the area is renowned for its Moor hot springs (モール温泉) deriving its mineral properties from reed and other native plants, which have accumulated deep in the ground together with groundwater over the ages, and is heated by geothermal heat before gushing out in the area around the hot spring resort. The Onsen is said to be gentle to the skin and has a higher content of natural moisturizing ingredients compared with ordinary hot springs.
As a bonus, at the end of the clip there is a walkthrough of the gender-segregated, communal open-air Onsen bath (温泉大浴場露天風呂), where you can get a better sense of the unique color of the Moor Onsen.
