How Does Water Safety Work in Japan?
Last verified: 2025-06 · Asia
1The Quick Answer
Tap water in Japan is completely safe to drink throughout the entire country.
2What You Need to Know
Japan's tap water is treated to some of the highest standards in the world and is safe to drink directly from any tap or public fountain. Bottled water is widely sold at convenience stores and vending machines but is entirely unnecessary for health reasons. Many Japanese people prefer tap water and municipal water quality reports are publicly available. When hiking or visiting rural areas, stick to tap or bottled water rather than drinking from streams.
