Is tipping customary in Japan?

Tipping isn't customary in Japan and is not expected – in fact, it will sometimes be considered impolite. As a general rule you should not leave a tip in Japan, with a few notable exceptions. Remember, if you are in one of the rare situations where you believe a tip is apppropriate, be sure to present the gratuity in an envelope (preferably a stylish one) and offer it with a small bow.
