Kotan no Yu is a special open-air bath located on the shores of Lake Kussharo in Hokkaido. The greatest attraction of this hot spring is the spectacular view from the stone bathtub, which is almost at the same height as the lake surface. Lake Kussharo changes its appearance with the seasons, and bathing in the snowy winter scenery in particular offers a special experience that you can't get anywhere else. The time spent in the bathtub gazing at the scenery of snow falling quietly and the misty lake surface is a moment that warms both the body and the mind. Another point is that Kotan no Yu is surrounded by nature, so you can expect the effects of forest bathing. Spending time in silence listening to the birds chirping and the sound of the wind is the perfect way to get away from the hustle and bustle of everyday life and reset your mind. In addition, the ingredients in the hot spring have the effect of smoothing the skin, making it popular with those seeking beautiful skin. It is also highly convenient as a tourist destination, and has facilities for tourists. Kotan no Yu is a must-visit for foreign tourists visiting Japan, as it is a spot where you can relax to your heart's content in the midst of nature.
