10. Don’t pour soy sauce on your rice.
In Japan, soy sauce is never poured directly on rice. Always pour soy sauce into the small dish provided specially for this and not directly on your rice or other food. Then use your chopsticks to dip the sushi or sashimi in the sauce.
11. Avoiding giving and receiving things with one hand.
In Japan, both hands are always used when giving and receiving things, including small objects like business cards. When paying at a shop or cafe, it’s common to place the money on the small tray next to the cash register instead of handing it directly to the cashier.
