Can I drink hot tap water directly in Japan?

Yes, I am in Tokyo, too. I'm near Shimizu Lily Station. Although the hotel has a kettle, it's too much trouble. If the tap is on, the water will be very hot. Drink it, and the taste will be ok. Japan has a high demand for water and food. If you can't drink, the boss will inform you in advance.

And I can't stand drinking cold water in winter. Haven't you noticed that when you eat in Japan, you always bring a glass of ice water? . .
