[Strong acid] Zao Hot spring "A tour of the three communal baths that flow from the sources for only 200 yen / day

Zao Hot spring in Yamagata Prefecture is on a par with Manza Onsen in Gunma Prefecture. style = "font-size: large;"> "Strongly acidic" hot springs.

Acidity (alkalinity)) is expressed by the pH value, and it is as follows in order from the one with the strongest acidity, but it seems that the ph value of Zao Onsen is 1.6.
・ Strong acidity: pH value 2.9 or less
・ Weakly acidic: pH value 3.0 to less than 5.9
・ Neutral: pH value 6.0 to less than 7.5
・ Weakly alkaline: pH value 7.5 to less than 8.5
・ Alkaline: pH value less than 80 to 10.0
・ Strong alkalinity: pH value 10.0 ~

The famous "Tamagawa Onsen" in Akita Prefecture seems to have a pH of 1.2, so it is not as good as it should be, but since "Kusatsu Onsen" has a pH of 2.05, it has a higher acidity than this.

As an effect, it is said to be effective for skin diseases, heart, constipation, and diabetes.

Zao Onsen has a long history, and the opening of the hot spring is 110 AD, so it has a history of more than 1900 years. It's amazing.

There are 3 communal baths "Kamiyu", "Shimoyu" and "Kawarayu" in Zao Onsen, but you can take a bath in all 3 places for 200 yen / day. It's a very profitable bathhouse because it's all flowing from the source and has a very tasteful atmosphere. Personally, I felt that "Kawarayu" was the best, but what about everyone?
It's a very nice hot spring, so please visit it once.
