The Scandalous Adventures Of Buraikan based on a kabuki play by the great Kawatake Mokuami. The movie is not available on video in the U.S. except for streaming on Hulu. However the region 2 DVD does have subtitles.
Lady Snowblood Based on the Koike manga. This film had a major influence on, and is in heavily referenced in, Quentin Tarantino's Kill Bill. Alas the AnimEigo release has gone out of print.
