Available editions
I came across a bootleg copy of Blind Woman's Curse on eBay. The title of this edition is "Black Cat's Revenge". It appears to be the same movie, though, and they both list "Kaidan Nobori Ryu" as the Japanese title.
I saw a comment online recently saying that Diskotec is working on creating an official US DVD of this title. I sent Diskotec an email asking if this was true. The reply stated that they are trying to find a good master and they are aiming to release "Blind Woman's Curse" by the end of this year.
