Question:

Answer:

Politeness.
Don't start your conversation with
1) In the US, we have...
2) In the US, we do...
3) In the US, we don't...
4) We Americans think...
etc, etc...

When you are in Japan, you should be aware of the fact that you are in totally different cultural environment. The Japanese don't care about your life in the US. Majority of the Japanese reaction would be SO WHAT?
When in Rome, do as the Romans do.
when in Japan, do as the Japanese do.
