The water extracted from Fujiyoshida City near Mt. Fuji is already deeply filtered by volcanic rock approximately 200m underground. As it is high quality water with very few impurities, heat treatment is unnecessary. Instead, we use four separate filters to remove extraneous materials and sterilize the water. At just 0.45 μm, the eyes of our filters are finer than the E. coli group and can capture microbes, bacteria, fungi and other water-based microorganisms.
By using a non-heated process, we are able to deliver the water with its natural mineral balance and pure flavor.
