Dining basics in Japan: free water, itadakimasu and finishing your plate
Most restaurants give you water for free, and two short phrases, itadakimasu and gochisosama, open and close a meal. They are polite habits, not rules you must follow.
Water is usually free
Japan's national tourism organization says that most restaurants provide tap water at no charge, and you can ask the staff for it.
- You often get a glass of water or tea when you sit down.
- If it does not come, just ask: "Omizu o onegaishimasu" (water, please).
- Bottled water and other drinks cost money. Bottled water is easy to find in vending machines and at convenience stores.
Two phrases for every meal
JNTO describes two common phrases:
- Itadakimasu: said before you eat. It means roughly "I am glad to receive this meal."
- Gochisosama desu: said after you finish. It means roughly "thank you for the meal."
You do not have to say them, but they are a friendly way to show thanks.
Other customs to know
- Finishing your food is polite. Leaving food is not liked, and asking to take leftovers home is generally not accepted. Order a little at a time if you are unsure.
- In a group, people normally wait until everyone has their food before they start.
- Before you take the last bite of a shared dish, ask first.
- Slurping noodles is accepted in most noodle shops. You do not have to slurp.
These are customs, not laws. Watch the people around you, and do what feels comfortable. Rules are often stricter in expensive restaurants and more relaxed in chains and casual shops.
Tipping and extra charges
There is no tip. Pay the price on the bill. Some izakaya add a small table charge, so see our otoshi article, and see our ticket machine article for shops where you pay first.
