I agree that Japanese women are very reserved and would rather put-up with any abuse as long as the family name isn't tarnished. Perhaps it'll be better if I just import some European girls. More fun that way.

I was thinking with the Ninjas that if they had techniques to kill and cause unconsciousness, then perhaps they had ideas towards pain and torture. With their range of weapons one could almost sense a whole new world of extreme BDSM.
