Tap Water

You can drink tap water in Japan.
Water in Nagoya comes from the Kiso River, and
is one of the most tasty tap water in Japan.

I've never taste all, but it is said that there are only 13 countries
where you can drink tap water safely.
If you have any objections to this, please let me know.
Thank you in advance.
