Anxiety about sanitation because the product is not sterilized by heat.

Non-heated sterilization is known to maintain the mineral components and taste of natural water. VanaH is taken from Mt. Fuji’s high-quality flowing groundwater from a deep place that reaches hundreds of meters underground, which does not need heat treatment. The hard basalt layers of Mt. Fuji protect the water from radioactivity and soil contamination, and they can ensure a safe and clean water quality. Our products have been treated by filtration through many layers of special filters to remove microscopic bacteria and cleared the strict requirements of the Food Sanitation Law.
