Happo Onsen is located on the one of the largest serpentinite rock layer in Japan.
The Onsen flows out of the underground seppentinite rock layer which forms the mantle in the deep.
The platonic action in the deep underground pushes the serpentinite rocks upward and triggers chemical reaction, through pressurization and high temperature , with the underground water to formulate one of the most highly alkaline onsen in the world,exceeding PH 11.
In general, alkaline onsen is considered to have skin care (smoothening) effect while having minimum negative effect to human body because of its purity i.e, not containing hazardous chemicals.
