I caught the final performance yesterday and holy crap, that was fun! The show is the show we know at the Ambassador--I'm very familiar with it, so it never shocks me and isn't new, but it was worth it for the encore alone. That was absolutely ridiculous in the best way possible. It was pure spectacle. Very Vegas showgirl-esque, but it was fabulously done.
I don't know much Japanese beyond Toyota, sushi, and Hello Kitty, but it was very entertaining to watch. The dancing, especially, was very sharp and clean.
