Top 10 Most Popular Japanese Water Bottle Brands You Must Try

Water safety is one of the concerns that many people have when visiting or living in Japan.

Is it safe to drink Japanese tap water? Is the taste and texture of Japanese water different from that of my home country? In Japan, where can I buy water?

We will answer these questions and introduce you to ten of the best water brands available in Japan.

First and foremost, tap water in Japan is completely safe to drink. Even when compared to other developed countries, Japanese tap water safety standards are high.

You may notice a difference in the taste and texture of the water you’re used to drinking. Japanese tap water (or Japanese water in general) is mostly soft, making digestion easier.

Also, because tap water is disinfected with chlorine, you may detect a slight chlorine taste in the water. The chlorine in the water is only enough to kill pathogenic bacteria and has no effect on the human body. Although, as previously stated, some people may notice it in the smell and taste.

What affects water quality?

There are two major factors that influence the texture and flavor of drinking water. “Water hardness” and “water PH level” are the two variables.

The number of minerals dissolved in water (particularly calcium and magnesium) is referred to as water hardness. Water with a high concentration of minerals is referred to as “hard water,” while water with a low concentration of minerals is referred to as “soft water.” Soft water is said to have a lighter texture, making it easier to drink than hard water, which is said to feel heavier in the stomach.

The PH level of the water is next, which has a minor impact on its taste. The PH level of water determines whether it is alkaline or acidic. The PH scale ranges from 0 to 14, with 7 representing neutral. PH levels greater than 7 are alkaline, while PH levels less than 7 are acidic. Alkaline water has a slightly bitter taste, whereas acidic water tastes, well, acidic.

The majority of bottled mineral water available in Japan is soft and slightly alkaline. Because most countries have hard water, the texture and taste may differ for you.
