This is a total spoof of all the Ninja TVs from Japan by Hong Kong movie studio. It has more ninjas than any ninja movie or TV made in Japan, and fight scenes are more kung-fu than sword fighting, but it's entertaining. If you figure in a brothel into the above picture, you get a pretty good idea what this movie is all about.
I think what they left out of the title is Sex. Because there're lots of Ninjas, killing, and ...fair amount of sex in this movie, all done in good humor .... "try a Japanese style .... ?".
First of a trilogy, this movie is one (actually three) of a kind Hong Kong movie that's pretty well made and entertaining to watch. It's surprising that this movie series isn't better known in this country (maybe not enough airtime on TV due to its graphical contents ?). Little too much sex to be a cult classic, but it deserves a place in HK cinema history.
