The city operates the area that is the source for our spring water and performs daily inspections to maintain water that is safe.
We produce safe and secure products through high-heat sterilization, which is a fundamental standard of quality control.
Using the experience that we have gained over many years, we maintain high sanitation and quality inspection standards in the distribution industry.
A weakly acidic, soft mineral water with that is rich in silica for an extremely smooth and great-tasting spring water.
|Please be aware that Shibushi Water is natural spring water, and because of this, there may be slight fluctuations in the numerical values for its nutritional components (hardness/pH-value) depending on the inspection date, environment, and other such conditions.|
Hardness is an indicator of the total amount of calcium and magnesium mineral content contained in water. To put it simply, water that contains a comparatively large amount of calcium and magnesium is “hard water,” and water that contains fewer of these minerals is called “soft water.” For infants and the elderly, “less than 60 mg/l” is ideal when considering water for those with fragile digestive systems and those who are sensitive to allergens. “Soft water” permeates through objects quickly, possesses superior absorbency, and smoothly eliminates waste products.
Silica is silicon oxide, which comprises approximately 60% percent of the earth's crust. It is also called silicon dioxide and silicic anhydride, among other names. Silica is a mineral that is very important for the human body and is an essential micronutrient. Though it is a nutrient that is important for the health of our bones, joints, blood, skin, hair, and nails, a single adult consumes 10–40 mg of silica per day. While young, our bodily tissues are able to continually take in a large amount of silicon. That is why younger bodies are flexible, elastic, are covered in soft skin, and our skeleton maintains its hardness. However, as we age, the level of silicon in our bodies drops, resulting in conditions such as the creation of dry skin and wrinkles, as well as bones that break more easily.
pH value expresses the degree of acidity and alkalinity for a substance. A low pH value means that the substance is an “acid,” and mineral water is generally in the range of “5-9.” Japanese water is often in the range of “6.5-7.5.” From a health perspective, a low concentration of acidity and alkalinity in the range of “6.0-7.5” is said to be the most suitable.
The legendary water “Shibushi Water” begins in the sprawling Shirasu-Daichi plateaus, an iconic feature of the Southern Kyushu region. We take clean spring water that has been naturally filtered over many years through these plateaus and fill it into bottles using high-performance mechanical equipment to produce extremely safe, natural mineral water. In addition to minerals such as calcium and magnesium, our water is also rich in silica, which is scarce in Japan.
