The second site is the official Japanese movie site. If some of us thought we have to wait extremely long for the movie (I still have to wait until the 16th of January)... we were wrong XD Japan will get the movie on April 4th 2009(!) with the official title "Twilight - first love". For the time being, there is a nice little site.
To finish this post nicely, I'm also posting the official Japanese movie poster, although it's a bit small. :)
