If I were you, I'd order the Japanese set. For years I've waited around for American releases of foreign films only to be dissapointed about the overall product(the Richard Sharpe series comes to mind).
Either way, the film is not going to come with all of the cool pack-ins that the Japanese have.
You young whippersnapper, back in my day we were stranded in the middle of nowhere with nothing but the shirt on our back and given the task of killing two buffalo and dragging them back to the homestead before we were considered a teenager.
