And some more info for you:

If you know these key Japanese customs, you?ll get closer to the locals and see beneath the surface of Japan.

1. Addressing Someone, Respect

Bowing is nothing less than an art form in Japan, respect pounded into children?s heads from the moment they enter school. For tourists, a simple inclination of the head or an attempt at a bow at the waist will usually suffice.
The duration and inclination of the bow is proportionate to the elevation of the person you?re addressing.

2. Table Manners

Some simple bullet points here:

- If you?re with a dinner party and receive drinks, wait before raising the glass to your lips. Everyone will be served, and someone will take the lead, make a speech, raise his drink, and yell ?kampai!? (cheers).

- You will receive a small wet cloth at most Japanese restaurants. Use this to wash your hands before eating, then carefully fold it and set it aside on the table. Do not use it as a napkin, or to touch any part of your face.

- Slurping noodles or making loud noises while eating is OK! In fact, slurping hot food like ramen is polite, to show you are enjoying it.

- You may raise bowls to your mouth to make it easier to eat with chopsticks, especially bowls of rice.

- Just before digging in, whether it be a seven-course dinner or a sample at a supermarket, it?s polite to say ?itadakimasu? (I will receive).

3. No Tipping

There is no tipping in any situation in Japan ? cabs, restaurants, personal care. To tip someone is actually a little insulting; the services you?ve asked for are covered by the price given, so why pay more?

If you are in a large area like Tokyo and can?t speak any Japanese, a waiter or waitress might take the extra money you happen to leave rather than force themselves to deal with the awkward situation of explaining the concept of no tipping in broken English.

Just remind yourself: a price is a price.
