Birthplace of Isohara Onsen

1931, where the predecessor "Watanabe Toshinokai" has dug a well at the foot of the Mt Tenpi, was blown up the eaves high hot springs (sulfur Izumi).
The next year, when I told him about it to my best friend "Noguchi Ujo" (the three major poems for nursery rhymes in Japan), I introduced the hot spring to "Isohara Kouta" and became widely known around the world.
