We pround thing about Japan

We pround thing about Japan, the waterworks has been developed to drink water. In Japan, we can drink water from the waterworks, but many countries is not the case.
In other countries, even though the waterworks has been developed, it is not mostly able to drink water. They mainly use tap water to do the laundry and take a bath. therefore, to drink water, they have to buy drinking water in the container PET bottles from the shop. In Japan, without such a trouble, we can drink water from the waterworks.
I think great Japanese technology which has been developed the waterworks to drink water.
