Stay hydrated with Japan's delicious drinking water If you eat in a restaurant, most places offer tap water for no extra charge. Just ask the staff. In fact, tap water is a source of pride for many of Japan's mountainous regions as cool, clean water is a product of the surrounding peaks.

Yes, in 2026, it remains a standard and highly valued part of Japanese hospitality (omotenashi) that water or tea is provided free of charge at almost all restaurants. Upon being seated, a server will typically bring you a glass of cold water or a cup of hot green tea immediately. At many casual establishments, such as ramen shops or "family restaurants" (e.g., Saizeriya or Gusto), you may find a self-service water station where you can get your own refills. The tap water in Japan is of exceptional quality and is perfectly safe to drink, which is why bottled water is rarely the default in dining settings. While high-end French or Italian restaurants in Tokyo may offer premium imported mineral water for a fee, the local "service water" is always available for free if you ask. In 2026, this practice persists as a point of national pride, ensuring that staying hydrated is never a hidden cost for tourists enjoying Japan's world-class culinary scene.
