"Soft water" is a term used to describe water with a relatively low concentration of minerals, specifically calcium and magnesium ions. The hardness of water is determined by the total content of these minerals.

In simpler terms, water with a higher concentration of calcium and magnesium ions is referred to as "hard water," while water with a lower concentration of these minerals is called "soft water."

Water with an exceptionally low mineral content is often referred to as "ultra-soft water." Enzan Natural Spring Water falls into this category, as it is considered "ultra-soft water" due to its extremely low mineral content.

The deliciousness of soft water is determined by the "mineral balance" and "sterilization method."

Perfect Mineral Balance:

Enzan Natural Spring Water is considered "ultra-soft water" because it has an extremely low content of minerals, specifically calcium and magnesium. This ultra-soft water has no bitterness or unusual taste compared to hard water, making it known for its smooth and mild flavor.

Hardness refers to a measurement of the total content of calcium and magnesium minerals in water. In simple terms, water with a relatively high concentration of calcium and magnesium is called hard water, while water with a lower concentration is referred to as soft water. "Ultra-soft water" is a term used for water with an exceptionally low mineral content, which describes Enzan Natural Spring Water.

Processing Methods That Enhance Deliciousness:

Water has a high ability to dissolve substances and can be influenced by the surrounding environment, which can affect its taste. Therefore, the processing and management of water after collection are crucial for enhancing its deliciousness.

Enzan Natural Spring Water is dedicated to pursuing deliciousness. To achieve this, it uses a "filtration process" involving four layers of filters with sizes of 1.0μm, 0.45μm, and 0.2μm x 2, following the pumping of raw water from underground. Importantly, this process is conducted without heating, known as "non-heat treatment."

Non-heat treatment, while challenging to manage and incurring higher costs, preserves the essential "dissolved oxygen" content in water. This helps maintain the original smoothness and mellowness of natural spring water, emphasizing the deliciousness of the water's taste.

We prioritize the health and safety of our customers when providing natural water. Therefore, we make every effort to deliver safe, high-quality, and delicious natural water without any decrease in quality or interruptions in supply.

We regularly commission external specialized testing agencies to conduct thorough water quality testing. This includes the examination of 45 critical parameters in water quality, mineral component analysis, and radiation testing. We use the results of these tests to maintain and enhance the quality of our products.

In addition, throughout the manufacturing and supply process of water, we have established an in-house specialized testing laboratory. This laboratory ensures that our products meet very high hygiene standards. Specifically, we conduct rigorous testing in three crucial areas: microbiological examination, physicochemical analysis, and sensory evaluation. At each stage, we implement strict quality control to ensure that our products are safe for customers to use without any concerns.

Our production line combines both mechanization and automation along with manual quality inspections and management carried out by experienced staff. This combination allows us to detect even the finest issues that machines alone might miss, further enhancing the quality of our water.

As a result, we have established a comprehensive quality control system to ensure that our water meets the highest standards, providing our customers with the best possible product.

1【Benefits of Silica】

Silica is one of the essential minerals that our bodies require. However, it is not naturally produced within our bodies and tends to decrease as we age. Silica is particularly crucial for maintaining skin hydration, firmness, beautiful hair, and strong bones. Therefore, it is essential to ensure a proper intake of silica through daily dietary sources.

Silica is efficiently absorbed by the body when it is dissolved in water. In this regard, high-quality mineral water sourced from the natural environment of Mount Fuji is recommended as an ideal way to incorporate silica into your diet.

2【Benefits of Vanadium】

Water rich in vanadium has gained attention in recent research. Vanadium, in particular, is known to help maintain proper blood sugar levels, potentially reducing the risk of lifestyle-related diseases such as diabetes and arteriosclerosis.

Given that many people today face the risk of these diseases due to modern lifestyles, consuming vanadium-rich water can be highly meaningful. Furthermore, vanadium has the capability to inhibit the increase of neutral fats generated during the transformation of the energy we consume into glucose.

Excessive accumulation of neutral fats can lead to obesity, making the consumption of vanadium water a topic of interest for those seeking to manage their weight and maintain a healthy lifestyle.
