Water Supply

Tap water in Japan is safe to drink. When your tap water turns cloudy, or when you suspect a water leak, contact the Water Supply Administration Center of the Waterworks Bureau.
To prevent water from freezing up in the winter months, wrap cloth around exposed pipes and faucets. Leaving water dripping from faucets during the night is also an effective way.
