Talking about water? Not really. Water is free in everywhere to drink. There is a service calls “Nomihodai”. If I try to explain it as simple as possible, it is a kind of Buffet.

Almost every in economy restaurant bar has this on menu and it is one of the best profit centers as Japanese are not good at to consume alcoholic drinks as their gene matter. What’s more, alcoholic drink makers help the restaurant bar to reduce their cost.

It is good or bad, many of foreign people who work in Japan mentions as the fault of Nomihodai, drinking more than ever.
