Here's the Japanese website which has a bit more content than the American site.
Personally, I'm really looking forward to this film. I just hope they don't give away too much more in the next couple trailers. I hate the trend of most movies giving away most of the plot and nearly all the "money shots" in the trailer. IMO, trailers should just give a feeling of what the film is going to be like, it shouldn't be like Cliff's Notes for moviegoers.
