So apparently there's a long running 'erotic comedy' series featuring female ninjas, called "Kunoichi ninpô-chô" Or "Kunoichi: Magic Chronicles".
Though, for a comedy, there's a lot of people dying. Some might have seen a scene from it like this:
This is very much par for the course. There's at least 9 parts of it, each running some 80 minutes.
Here's part 2:

The 'main zako action' is at 20:00 minutes where the 'hero' fights the head honcho of the opposition and his 3 Kunoichi who are rather unceremoneously cut down.
However there's a lot more worth viewing here. The plot is that Christian Rebels are trying to convert people and to help with that have gotten a shipment of gold. The goods are hidden and the clues to find it are written on 5 small jingle bells. The bells are hidden up the vaginas of the priestesses and jingle when you point a cross at them, and tend to fall out when they cum or are killed.
Also the hero is the Shogun and apparently can't get a boner. There's lots of female death, sex and sillyness in here. I recommend.
