Have you ever sat down at a restaurant in Japan and been served a glass of ice water or a cup of hot tea without even ordering?
For many travelers, this might raise a red flag: “Wait, I didn’t order this. Are they going to charge me later?”
Rest assured—it is completely FREE! This is not a hidden fee or a scam. It is a fundamental part of Japanese hospitality, known as Omotenashi.
Here is everything you need to know about drinking water at restaurants in Japan.
1. The Welcome Water is 100% Free (and Unlimited!)

In almost every sit-down restaurant in Japan (from casual diners to high-end spots), you will be served a glass of water (or tea) and a wet towel (Oshibori) as soon as you are seated.
- Zero Charges: You will never see this water on your final bill.
- Free Refills: If you finish your glass, the staff will often refill it for you. In many casual restaurants, a pitcher of water is placed right on your table, and you are welcome to help yourself.
💡 Useful Japanese Phrase: If you need a refill and the staff hasn’t noticed, just catch their attention and say: “Omizu, onegai shimasu” (Water, please).
2. Food Courts and Casual Shops: Look for the “Self-Service” Stations

If you are eating at a shopping mall food court, a ramen shop, or a fast-food chain, water might not be brought to your table automatically. In these places, it is usually Self-Service.
- Find the Water Dispenser: Look around for a station with a water machine and a stack of small paper or plastic cups.
- Help Yourself: You can take a cup and fill it up as many times as you like. Again, this is completely free!
3. Quick Warning: Don’t Confuse “Free Water” with “Otoshi”
While water is always free, there is one unique Japanese food culture that does cost money: the “Otoshi” (お通し).
If you visit an Izakaya (a Japanese-style pub), you will often be served a tiny appetizer before your main order arrives. This is a mandatory table charge (usually around 300 to 500 yen per person).
- Water / Green Tea: Always Free.
- Otoshi (Tiny Appetizer): Paid (Izakaya only).
If you see a small charge you don’t recognize on your Izakaya bill, it’s likely the Otoshi, not the water!
Summary: Tap Water in Japan is Safe and Delicious!
Japan is one of the few countries in the world where tap water is strictly regulated and perfectly safe to drink. The water served at restaurants is either high-quality tap water or filtered water.
So, when you sit down at a restaurant in Japan and get a cold glass of water, don’t worry. Just sit back, take a sip, and enjoy Japanese hospitality! Japanese culture.
