Geographic Features and Water Source of Kanazawa Shimizu
The water source of Kanazawa Shimizu originates from the groundwater system at the foot of Mount Iwate. Mount Iwate is an active volcano with an elevation of 2,038 meters. Rain and snowmelt water falling on its foothills infiltrate deep into the earth over many years, filtered through volcanic layers, and then spring forth.
Blessings of Mount Iwate and Hachimantai
Hachimantai City, where Kanazawa Shimizu is located, is a region surrounded by two mountainous areas: Mount Iwate and Hachimantai. This geographic condition, combined with abundant precipitation and the natural filtration system created by volcanic soil, produces clear and plentiful spring water.
The seven springs scattered along the Matsukawa River each have independent discharge points, yet are believed to be supplied from the same groundwater system, with water quality and temperature remaining relatively constant.
