I don’t have any Japanese friends so I don’t know. I’ve heard from other people’s experiences that this is what they’ve felt too. As an outsider you are never treated the same. But even as a Japanese person you have the public you and the real you. Most of the time you are interacting with people’s public persona and never get to know the real them. Or so they say … 

 this is true.
further, there's not any expectation or desire that you would even get to know the "real them"
