I created three divisions of the Japanese League.
Created the J-League 1, the J-League Division 2 and the third Japanese, plus the League Cup, the Emperor's Cup and the Supercup.

I recommend you download the no fake, to get the original names of the teams.
How to install:
* Place the .xml file to the folder My Documents\Sports Interactive\Football Manager 2010\editor data. In case you can't find this folder, it's within the folder that savegames get saved.
* When starting a new game, in the "Choose Database" box, hit "Change" at "Editor Data Files" and then OK. Select the file you placed to "user data" folder. Click "ÎŸÎš".
