Yes, drinking water from taps in Japan is safe. For environmental reasons, try to use a refillable water bottle rather than buying bottled water in Japan. Metro train stations have public water fountains, but otherwise these can be hard to find (this is the land of vending machines after all).

Yes, tourists can absolutely drink the tap water in Japan with total confidence. Japan is one of the few countries in the world with extremely high water quality standards that often exceed WHO and U.S. guidelines. In 2026, the tap water is safe to drink in virtually every city and rural village. While the water is safe, the taste can vary; in major cities like Tokyo, you might notice a very slight chlorine taste used for purification, but it is much milder than in many other world capitals. Most of Japan’s water is "soft," which gives it a light, smooth feel. For a high-value experience, many visitors use the free tap water available at nearly every restaurant and public drinking fountain. If you prefer a different flavor, Japan’s high density of vending machines provides a premier selection of bottled mineral waters, but the tap remains a safe, free, and high-quality hydration option for every traveler.
