Introduction to water sampling areas and water quality
Water sampling areas
Fuji-Sanroku (foot of Mt. Fuji)
1273-128 Hirano, Yamanakako-mura, Minami-tsuru-gun, Yamanashi prefecture
As the rainwater and melted snow seep into the ground around Mt. Fuji, the process by which this flows into ground water causes the minerals in the strata to dissolve, producing natural water with an abundance of minerals.

Silicon
Silicon (silica) is a mineral found in seaweed and shellfish, and is an important mineral for the formation of bones, hair, and nails, The intake of silicon is said to be effective in preventing arteriosclerosis, improving the immune function, and making bones more robust.

Water Treatment Method
The well that is owned by the Fujinogensui Yamanako Factory, which manufactures “FUJI SUN SUI” is a deep well with extremely clean water from which no E.coli bacteria or microflora at all have been detected.
As a further measure to ensure safety, the Yamanako Factory that performs bottling with this precious water source uses four high-performance filters of 5㎛ (microns)→1.5㎛→0.5㎛→0.2㎛ to produce its water.
As a result of this process, an advanced production line has been introduced which means that even in the event of contamination with mold, E. coli bacteria, or microflora, these would be completely removed.
This unheated water treatment system, which values natural minerals, is already commonly used in mineral water production plants in EU countries.
