Kaikei / Check
The request for the bill/check to pay for the meal at the table or register.
While payment location varies by shop (table vs. register), crossing your two index fingers to form an 'X' is a well-known non-verbal sign for 'the bill, please.'
Call the waiter and say 'O-kaikei onegai shimasu' (The bill, please) or make the crossed-finger 'X' gesture from a distance.
What non-verbal hand gesture is commonly used in Japan to signal the waiter for the check?
