Although it is not customary to tip in Japan (hurrah!), upscale establishments will sometimes add a ‘service charge’ to the bill. This is usually indicated somewhere on the menu or upon entrance. Also, be aware that many places charge ‘cover charge’ or ‘table charge’. Depending on the place, you might receive a small appetizer for this money, or sometimes just a seat. Prices vary; I’ve had to pay cover charges anywhere between a few hundred yen (3$) to over two thousand yen (20$).
