Hokkaido Shari Town
KIKI Shiretoko Natural Resort is an accommodation-type resort nestled in the forest of Shiretoko Utoro. In January 2023, the large public bath was completely renovated, featuring four unique saunas, a cold plunge bath, and a garden open-air hot spring with natural flow. Windows filtering sunlight and terraces overlooking the forest create a spatial experience of heat, cold, water, and scenery. It offers a stay where you can simultaneously enjoy the nature of Shiretoko and a well-prepared bathing experience.
TypeNatural Hot Spring
The sodium-chloride bicarbonate hot spring bubbling up on the hill of Shiretoko Utoro is supplied 100% with natural flow, without heating or adding water, in the garden open-air bath. The water clings to the skin, and its gentle warmth lingers after bathing. Surrounded by forest and sea, you can reset your body in harmony with nature.

The 'Krouna' is a dark sauna inspired by a cave, with walls and ceilings in black tones. Performing self-löyly in this light-blocking environment significantly intensifies the heat concentration. Equipped with aroma pots, it offers a rich aromatic experience, purifying not only through sweating but also through all five senses.
Water QualityTap Water
Capacity3people
The standing cold plunge bath next to the indoor bath is about 120cm deep. With the push of a button along the wall, you can experience a waterfall-like water flow, providing a significant cooling impact right after sweating. Depending on the season, the cooling water is around 8-15°C, quickly calming the core body and smoothly guiding you to the outdoor air bath or relaxation space, supporting the 'totonou' pathway.
