Above is a nice poster for Mekura no oichi monogatari: Makkana nagaradori, aka Crimson Bat: The Blind Swordswoman, starring Yôko Matsuyama, Chizuko Arai, and Jun Tatara. The first in a series of four Crimson Bat movies, this was in the same vein as the long running Zataochi series, and was a precursor to other movies featuring angry blind swordswomen like Black Cat’s Revenge, which we took a look at a few months back. Basically, in Japanese movies if you meet up with a sword-wielding blind woman—even one that looks as innocent as Yôko Matsuyama—either run screaming or make out your last will and testament on the spot. Plenty of reviews of this one online, so you don’t need our input. We'll just tell you that it has all the elements—betrayal, revenge, arterial bloodspray, all that good stuff. You can check out a fight scene here. Mekura no oichi monogatari: Makkana nagaradori premiered in Tokyo today in 1969.
