Following WWII, along with Japan’s rapid growth in economy and population, demand for home and industrial water rose; prompting the construction of multi-purpose dams to ensure a stable and adequate water supply. Simultaneously, legislation governing water quality were enacted to safeguard citizens’ hygienic safety.

Well, that’s really exciting!

How?

Let’s have a look!

Taste of Japanese Tap Water

The tap water of Japan is primarily soft, and pH level ranges from 6 to 7.

Soft water has a gentler flavor and is easier to drink than hard water.

The water that has high mineral content is hard water.

Once, a European friend of mine came to Japan for a holiday trip & after a few days, she noticed something unexpected.

She realized her skin & hair got smoother than before that she could ever imagine.

Then I explained to her that soft water is kind to hair & skin due to the lesser amount of minerals.

Soft water good for skin and hair

According to WHO criteria, soft water has less than 120 milliliters of magnesium per liter, whereas hard water contains more than 120 milliliters per liter.

But those who are used to hard water may feel inadequate after drinking soft water.

No worries!

There is also a way to do it.

If you choose to drink hard water during your trip, there is a huge variety of mineral/bottled water available in Japan
