I haven't got round to this one myself yet along with a bunch of Teruo Ishii's other flicks.
I caught 
Shogun's Sadism (Oxen Split Torturing) awhile back and thought it was good.   
Twisted stuff that the Japanese director's pull off so well.  I'd buy it right away if I saw it.  Most of the places I get stuff from don't seem to stock 
Japan Shock stuff unfortunatley. 
Think I'll watch 
Horrors Of Malformed Men tonight seeing as your thread has reminded me of it :D
