Yeah but you can play as Germany, in my computer etc in the Football Manager folder somewhere you can delete a file with 'fake' in the name I think, google it and have a look
Just search all files and folders for file "Fake", delete all files, there's between 1-3 depending on which patch you have, and this will re-instate the German National side, however you will need to start a new game...
Search all files and folders for "nleague" approx 5 will appear depending on what patch you have, delete all files that appear and that'll re-instate the Japanese National side... but to be honest it's not worth doing! 8-|
