Japanese movies can be really fucked up in general.
There's also Incredible Torture Show (it's a low budget '70s movie but I love it), almost every early Dario Argento (i.e. Suspiria,Tenebrae), almost every early Lucio Fulci (i.e Zombi 2, The New York Ripper, The Beyond), Herschell Gordon Lewis stuff , Maniac (1980) and the Elijah Wood remake.
Again not much sword fighting in them but that criteria is hard to fulfill because they tend to be swashbuckler movies not horror stuff.
