What is Alkaline Ionized Water?
"What's the difference between alkaline ionized water and regular water?"
"Why do health-conscious people choose it?"

Many people probably have these questions.
In recent years, alkaline ionized water has gained attention with the growing awareness of health and beauty. It is chosen by those who want to be particular about their daily hydration and those looking for easy-to-drink water.
This article will clearly explain what alkaline ionized water is, its differences from regular water and natural water, and key points for choosing it.
Alkaline ionized water is water that exhibits alkalinity.
Water has a property called "pH".
pH is a measure indicating how close water is to acidic, neutral, or alkaline properties.
Generally, water with a pH higher than 7 is considered alkaline water.
Among these, water manufactured and sold for consumption is sometimes called alkaline ionized water.
What's the difference from regular water?
There are various types of water consumed daily.
- Tap water
- Mineral water
- Natural water
- RO water (filtered water)
- Alkaline ionized water
Among these, alkaline ionized water is sometimes chosen for its characteristic pH value and taste.
For example,
- it feels mellow
- it feels easy to drink
- it's easy to incorporate into daily hydration
are some of the comments received.
*Individual experiences may vary.
There is also natural alkaline ionized water.
When people hear "alkaline ionized water," some may imagine water produced by a machine, but there is also naturally occurring alkaline natural water.
Natural water that exhibits alkalinity due to the formation of its mineral balance by natural environmental factors, such as geological strata and volcanic belts, also exists.
Therefore, alkaline ionized water is not necessarily artificial water.
Drinkability also changes depending on hardness.
When considering the deliciousness of water, "hardness" is also an important factor.
- Hard water: Rich in minerals, with a robust taste
- Soft water: Smooth and easy to drink
Many people in Japan prefer soft water, and a large number tend to choose soft water for daily consumption.
