About this ingredient
Spring water filtered through Mt. Fuji's volcanic basalt aquifer — a 50-100 year underground filtration cycle that produces water with characteristically high silica content (40-100 mg/L vs typical ~10 mg/L) and low contaminant load. The Fujinomiya, Oshino-Hakkai, and Yamanashi aquifer points produce commercial spring water for both retail bottling and B2B beverage / cosmetic ingredient supply. Distinct from existing Muroto deep-sea-water entry. Used in premium bottled-water retail, sake brewing, and increasingly cosmetic moisturising lines positioning around the silica content.
