So-So Japanese

The first thing I heard when I had decided to live US was:

You have to hold door for next person.

People feel very rude if a door shut in front of him or her. It's a very bad manner.

It was impressive for me, and surprised to see that it was true in US. Even teenager or people looks like gang, every people hold doors for next person.

Maybe it is wrong to say "This is not a Japanese manner". We are doing the same thing, but not so strict. This is just an option for kind people.

I agree that this is a good manner, but when you would meet such a "rude" person and you could find he or she is Asian, please be patient.

We don't want to be rude. Just we don't really have the custom.
