Located almost in the center of the Kofu Basin in Yamanashi Prefecture, Isawa Onsen is the largest hot spring resort in Yamanashi Prefecture and one of the best in the country. In 1961, a hot spring suddenly gushed out from an orchard, and the hot spring that flowed out became famous as "Aozora Onsen" (blue sky hot spring). Blessed with fruit and hot springs, Isawa Onsen has quickly become known throughout Japan and attracts a large number of tourists. Also, being only an hour and a half away from Tokyo by car or train, Yamanashi is a convenient location for access to the Tokyo metropolitan area, and its environment full of fruit picking and nature is attracting a lot of attention as a tourist spot.
The hot water is high quality hot spring water that gushes out from the premises. The quality of the water is alkaline simple hot spring, which is also known as "hot water for beauty and beautiful skin" because it makes the skin smooth and smooth. It is also said to have a cleansing effect that removes dead skin cells. Enjoy the abundant hot spring water in the large public baths, private baths, and storm baths.
