What is the proper protocol for meeting a Japanese couple (from Japan visiting the US) for the first time?

Answer 1

I think that learning some Japanese would be a terrific idea. If you are going to visit them, a small gift is appropriate.

Gifts should be wrapped in mute-colored (but never white, which symbolized death) wrapping paper. Dull yellows, greens, oranges and blues are acceptable. The Japanese do not appreciate flashy or bright colored wrapping paper. I used to work for an engineering firm where we had Japanese clients, and had to get small gifts for them.

Here's what I found on Wikipedia about etiquette about gift giving and going to someone's house:

It is considered impolite to go to someone's house without a gift. In Japanese this is called tebura 手ぶら (empty-handed). A gift is usually brought in a paper bag (preferably a bag from the shop where you bought the gift), the gift is taken out of the bag and the bag is placed underneath the gift when giving it to the host, using both hands. The gift is often presented when shown into the living room, saying "tsumaranai mono desu ga"　つまらないものですが (Literally: "It is a meager thing, but...") to show modesty. If the host offers something, it is polite to make a soft declination saying "okizukai naku"おきずかいなく (please don't go through the trouble), but the guest can gladly accept if the host asks for the second time.

Hope this helps!

Answer 2

They they might speak English, why not greet them in Japanese? How about a few phrases? They would be honored that you took the time to at least make them welcome in their own language. As for a gift, keep it very small. Usually, a bag of oranges or tangerines would be welcoming.

Answer 3

Give them a nicely wrapped present

Answer 4

There is no protocol. A warm welcome is as good as it gets.
