Hicom Water Minamiaso Factory Tour

The Outer Rim Mountains of Aso consist of peaks with elevations exceeding 1,000 meters. Aso features one of the world's largest calderas, with the region formed through repeated ancient volcanic eruptions, creating layer upon layer of volcanic deposits. These accumulated strata act as a large natural sponge, slowly filtering the water that drains through the surface and enriching it into mineral-rich groundwater. This groundwater from Aso is drawn from a 100m-deep well at the Minamiaso factory, bottled without heat treatment to maintain its freshness, and delivered to customers. We invite you to observe the production process of this 100% natural mineral water and we hope to convey the wonder and importance of nutrient-rich natural water to as many people as possible.
