Muten,
I'm with you. Being "old school", I remain a huge fan of Yu (Yuu) Kawakami who, to my knowledge, has never done any uncensored movies with any studios. She has been around for quite some time but since I've not seen anything "new" from her recently, may have retired.
I've watched her over the years as have seen her go through the various stages of eventual exit but have yet to ever see anything uncensored from her, though I'd love to!
If anyone HAS seen any uncensored work of hers, I'd LOVE to find it! Until then, I'll continue to use my imagination...
