The news section of the official site ( has been updated, now with great news to the fans. The Japanese DVDs will contain also one more thing that the other countries didn’t get : a passport to Middle-earth. Each DVD from FOTR will contain a passport with a serial number, which will allow the buyer to join special events and campaigns.They don’t specify any event or campaign yet, but looks like the whole thing will last ’till the release of the ROTK DVD.
Thanks to Elenah for that!
