瞬間連写アクションポーズ02 殺陣・ソードアクション篇 [単行本] and 瞬間連写アクションポーズ03 ヒロイン・アクション篇 [単行本] Real Action Pose Books.
The sword one is neat because they have a kimono on and kimono off version of each shot most of the time. And the third book looks really nice, I hope I can find it. Bought this also from Kinokuniya in hopes one day I do an action comic mixing a storyboard/comic style for the action scenes. An example of this would be some panels Agasang did I still swoon over.
Also I wonder how many takes it took to get that cool scene down where he kicks the guys sword back in.
