What you are doing is cool but I don`t think it will help.

I have lived in Tokyo for 12 years and my wife is JP and plays 14 and I can speak pretty decent Japanese. Well we both joined a PF group for Titan EX and I was speaking Japanese with the party but as we were going to enter one a party member pointed out I wasn`t Japanese. Both me and my wife told them that I can speak and understand Japanese, she also told them I was her husband and we were playing next to each other and that she could explain anything I might not know. Well they still tossed up the JP Olny and booted me. Some JP only is because of communication, some because they think non-jp players are inferior, and others are just racist.

To those who say "Why not go to a NA/EU server" JP refers to the location of the data center not the offical language spoken on the servers.
I also remeber Yoshida saying people should play on whatever data center they want and/or the one closest to where they are in the world.
