What Otoshi Is
At many izakaya, a small dish called otoshi (お通し) is brought to your table as soon as you sit down, even if you didn't order it. It's usually hard to decline, and functions as a de facto seating charge. The price varies by shop, but it's often in the range of a few hundred yen.
Otoshi vs. Charge / Service Fees
Some shops add a separate "charge" or service fee on top of otoshi, while others only have one or the other. This is often noted on the menu or a sign near the entrance, so it's worth checking when you sit down if you're curious.
No Tipping
In Japan, the listed price is generally considered to already include service, so tipping isn't customary. There's no need to pay more than the bill, and offering extra can sometimes confuse staff.
How to Pay
Some restaurants have you pay at a register near the entrance, while others bring the check to your table and expect you to settle up there, either by calling staff over or carrying the check to the register yourself.
Splitting the Bill
For group meals, saying you'd like to split the bill ("warikan") often gets the total divided evenly among everyone. If you'd like separate checks, it helps to mention this when ordering.
Bring Some Cash
Many shops still expect cash, so it's worth carrying 1,000 yen notes and coins. See Cash-only shops are common for more.
Asking for a Receipt
Saying "ryoshusho o kudasai" (a formal receipt) usually gets you what you need. If you need a specific name on it, mention that when asking.
Related dishes
Otoshi is closely tied to izakaya culture, often served alongside dishes like yakitori and enjoyed with sake.
