Afuri Mizumoto

Tanzawa Oyama. Even on a sunny day, the summit is often covered with fog and haze, and has been called Afuriyama since ancient times. Along with Afuri Shrine, which turned "rain", it has been known as a place for raining since ancient times. The rain drops that fall into the trees permeate the ground and slowly flows from the top to the foot over a long period of time. Yoshikawa Brewery pumps a clear underground underground water from the three wells to brew alcohol. "Hard water" is water that contains a lot of minerals such as magnesium or calcium. Yoshikawa brewing water is a hard water with a rare hardness of 150 in Japan. It indicates how water has been polished in the process of going down the ground at the foot of the mountain over the years. Hardwater promotes the fermentation of yeast and can be brewed even at low temperatures, making it clean and beautiful.
