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.

Two phrases for every meal

JNTO describes two common phrases:

You do not have to say them, but they are a friendly way to show thanks.

Other customs to know

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.

FAQ

Do I have to say itadakimasu?

No. It is a custom, and visitors are not required to say it. A smile and a nod are fine too.

Can I ask to take leftovers home?

Often not. Many restaurants do not allow it, so ask politely only if you really need to.

Is it rude to slurp noodles?

No. It is accepted in most noodle shops, but you do not need to do it yourself.
