Misaka Ryokan

The evaluation is based on day trip bath use only. Hirugami Onsen uses mixed spring water from four source wells. However, there are very few accommodations that use natural hot spring water, and I learned through word of mouth that this open-air bath has a rare natural hot spring water source, so I decided to use it. The spring quality is an alkaline simple sulfur hot spring with a pH of 9.8 and a source temperature of 48.2℃. It is true that the hot water is fed directly from the source, but since the hot water is dripped little by little from a tall spout, the temperature felt like 40 degrees Celsius, so you could take a long bath. Compared to other accommodations, the open-air bath is not a circulating system and does not use chlorine, so the hot water felt fresher. It was worth the visit. However, this can be said about the spring quality of Hirugami Onsen as a whole, but for a sulfur spring, there is almost no sulfur odor, and although the pH is 9.8, it is definitely a beauty bath with a slippery feel. However, it didn't have as amazing a slippery feeling as Kannon Onsen in Izu.
