The spring quality is a "calcium, magnesium, sodium, nitrate, and hydrogen carbonate hot spring" with a neutral pH of 6.6 and a source temperature of 50.2℃. It is a hot spring that contains a lot of metasilicic acid, is rich in ingredients, feels good on the skin, and seems to be very effective. The water is drawn from the source over several kilometers from the North Jigokudani Valley of Mt. Myoko and is naturally cooled to around 42 degrees Celsius, with an abundant amount of hot water flowing directly from the source without any heating or addition of water. The indoor bath is quite large, and the open-air bath is small and lacks a view, but it is hotter and has more flowers, giving you a sense of the quality of the spring water. It is only used for day trip bathing. Since the hot springs are not self-spouting, the hot springs cannot be said to be fresh, but the quality of the hot springs more than makes up for this, making me realize that Akakura Onsen is one of the best hot springs in Japan. This Akakura hotel has a spacious bathroom and is fully equipped. The inside of the hotel has a sense of history, and the front desk staff was very helpful.If I had a chance to come next time, I would like to stay there.
