TDR's official japanese site has loaded up their video page with new short clips from both TDL's Halloween event, and TDS' new 5th anniversary offerings...
The page is loaded with many links to these short clips..., and some links (such as the TDS 5th anniversary) will take you to yet other clip options beyond the initial page. Lots of fun for your viewing pleasure... but sadly, this page is only available in Japanese.
Just click on the blue japanese letters next to the photos and presto. Videos load up automatically after a few seconds (with broadband service)
