What’s The Texture and Taste of Tap Water In Japan?

Water tastes different in several parts of the world and not just the taste differs but also the texture, smell, and even the contents of minerals. If you’re from a Western country then the mineral contents in the water are highly likely to be more than the water that’s available in Japan. 

For instance, the magnesium level in the water that’s available in Europe is over 120 grams of magnesium per liter while in Japan the water contains fairly less than 120 grams of magnesium per liter. 

This can also differ for other types of minerals in the water as well such as calcium, potassium, sodium, iron, etc. Even some areas within Japan are said to have water that tastes and feels different.

Since the water available in Japan has a low magnesium level, this makes Japan’s water soft, and in other words, it’s called “soft water” and water with over 120 grams of magnesium per liter is called “hard water”. Hard water is what’s prevalent across most European countries. 

Hence if you’re a tourist from a European country who’s visiting Japan, you’re most probably going to find the taste and texture of the water in Japan quite distinct. 

The most noticeable differences would be the smoothness of the water and how it feels on your skin, especially if you’re taking a shower. You’ll also notice how the soap gets foamier when it’s washed with soft water. 

Soft water also has great benefits for your skin and hair because evidently, the water wouldn’t be so hard on them. 

Soft water also tastes slightly sweet compared to hard water. Ultimately, this also makes the food made with soft water taste much better and not to mention the taste of fish available in Japan which tastes phenomenal.
