Is Water Free in Japanese Restaurants? How to Ask for a Refill
A glass of water arrives before you have ordered anything. Is it included, or will it appear on your bill? And if nobody brings you a glass, should you wait?
In many Japanese restaurants, plain drinking water is complimentary for diners. Staff may bring it to your table, or you may need to help yourself. Bottled water, sparkling water and other drinks on the menu can be separate purchases, so check before ordering.
Is the water brought to my table free?
Usually, yes. Japan’s national tourism organization says most restaurants offer tap water at no extra charge. A small glass of plain water served when you sit down is commonly part of the service. Source: JNTO
You do not need to assume that an unexpected glass is an extra order. If you are unsure, ask the staff whether it is complimentary before accepting a bottled or specialty drink.
Nobody brought water. What should I do?
Look around for a water pitcher on your table or a self-service area with glasses. Follow the signs rather than assuming every drink dispenser is included.
For example, Saizeriya’s own guide explains that customers collect a glass and serve themselves water at the drinks counter. Its drink bar is a separately priced menu item. The water and paid drinks can be in the same area, so their location alone does not tell you what is included. Sources: Saizeriya’s service guide, drink-bar menu
If the setup is unclear, ask a member of staff where to get water. There is no need to work out an unfamiliar machine by trial and error.
How do I ask for more water?
If the restaurant serves water at the table, get the staff’s attention politely and ask, “Could I have some more water, please?” You can also say O-mizu o mō sukoshi itadakemasu ka? (お水をもう少しいただけますか？).
Leave your glass on the table where the server can reach it. If water is self-service, follow the restaurant’s instructions and refill your glass at the designated station instead.
A server may direct you to a pitcher or water station. That simply tells you how water service works at that restaurant.
What about bottled water and sparkling water?
Check the menu price before ordering either. Do not assume that a bottle offered by a server, or a drink listed on the menu, has the same arrangement as the complimentary glass of water.
If someone asks “Still or sparkling?” and you want ordinary drinking water, ask whether complimentary water is available. This is clearer than choosing a drink without knowing its price.
Can I drink the tap water?
JNTO advises that tap water in Japan is safe to drink. Follow any local notice marking a particular supply as non-drinking water. Source: JNTO FAQ
Can I refill my own bottle?
Ask first. Water provided with your meal is not automatically an invitation to refill a large personal bottle. “May I fill my water bottle here?” gives staff a chance to explain the restaurant’s policy.
When you sit down, look for a glass, a pitcher or a water station. If you cannot tell what is included, a quick question is enough—you are not expected to know every restaurant’s system on your first visit.
