It starts with the water
Mt. Fuji's rainwater and snowmelt gradually permeate through a unique layer of basalt. It takes a decade or two for it to be filtered by the geological strata and return as underground water ready for use. Matsuyama searched out purest possible water, and found it on the northern foot of Mt. Fuji. The source is located in Fujikawaguchiko in Yamanashi, an area situated inside a national park and known for its abundant, crystal-clear water. Even the drinking water at our Fujikawaguchiko Factory comes from a deep well that taps Mt. Fuji's underground water. The water is brought up from the depth of around 200 m and is used in our products as either soft water or as purified water.
