Justmyview, I lived and worked in Japan for off and on for almost ten years and have also visited countless times for stays as long as 90 days, as permitted by Japan's visa waiver program.  I have traveled from Okinawa in the South to Wakkanai on Hokkaido which is a far north as one can go in Japan.  I have traveled by train but mostly by rental vehicle.  I have visited every large city and many small remote country and mountain villages where they rarely see a gaijin.  I met many real Japanese and was welcomed with open arms everywhere I have been.  Unfortunately, I can't say that for some of the places I have visited in the USA.  I am sorry your experience in Japan, if you have any, was not as wonderful as mine.
