One of Hot Springs with Most Large Aluminum Ion in Japan -Esan Onsen in Hakodate-

June 19th, 2014

Esan Onsen Ryokan

Esan Onsen Ryokan (恵山温泉旅館) is a hot-spring ryokan in Esan, Hakodate city located in the eastern part of Hakodate city and was founded in 1932. Interior decoration of the ryokan has an atmosphere such as the Showa period. There are Azalea Park and a trailhead to Mt. Esan (恵山) near a building. It was written on a sight map that a observatory nearby (about 20 minutes on foot) was located 500 m from a parking lot. I supposed that it was easy to climb because the distance was very short, but there was very rough path and the path was a steep slope, and I was considerably out of breath.

At a bathhouse, there is 1 indoor bath. A free-flowing hot springs without too hot are overflowing from a bathtub. The hot springs are aluminum and iron sulfate spring, and are clear and colorless and have sour taste and no smell. The sum total of the hot spring ingredients are 5.296 g. What you should mention specially is the aluminum ion. The aluminum ion is said to be most large in Japan with the hot springs of Ishida Onsen (石田温泉) in Esan, and it has 363.5 mg, too. The hot springs are famous for strong acidity with ph 2.2. An alkali soap does not lather for neutralizing. The power of nature is great.

Because the hot springs were drinkable, I drank the hot springs. It was bitter and sour taste such as tonic water. I regret that it was not an effect. But I supposed that it might be tasty when I poured the cooled hot spring into a liquor and drank it. But please be careful because you sting your eyes when the hot springs get into your eyes. By the way, there is no shower at the bathhouse. Bathers take a bath after pouring the hot springs on their body with a water tub. Because there was not a restroom at a dressing room, you should get a wash beforehand at the restroom at a corridor. In addition, a staying is possible, too.
