Don't stand your chopsticks up in your rice like you're a matador. Don't stick them up and leave them there.
Leave that for funerals. :)

Do not pass any food or anything to anyone, from your chopsticks to theirs, ever.
The only appropriate situation is after the body is cremated and you're passing a bone. Someone will tell you which one and when.

Don't put sugar in your green tea. It's like putting sugar in diet coke: it may actually taste okay, but it's considered strange and gross.

Do not eat while walking, it is generally frowned upon. Sit down at a restaurant to eat.

No need to put extra wasabi on your sushi or in your soy sauce, as they chef has already put a bit of wasabi in between the fish and the rice.

In restaurants, if they give a wet towel, it's okay to wipe your hands. Face - hmm. But no armpits. :)

Upon receiving your meal from the server (or even in someone’s home) it’s polite to say “itadakimasu” which is similar to *saying grace* or being thankful for the food.

The wet towel given at restaurants is for your hands. Only old people sometimes use it to clean their face.

When saying "itadakimasu" before eating, put your hands in a "prayer" position and slightly bow your head. "Itadakimasu" is the equivalent of "saying grace" before a meal.
