I think I may have asked this before(i'm not sure).
In Japan how would somebody most likely start a conversation?
And how would you say hi?
I mean I know hi is konnichi wa, but how would you express your self.
Because I heard that you never look the other person in the eye.
I'm mainly just asking these questions because if I ever really go to Japan
I don't want to make myself look like a fool.
