Shogun Assassin (1980) is a collection of popular Japanese movies about a rogue samurai and his carriage-wheeling baby boy, the toughest buddy pictures ever made. But a swordsman can’t live on blood and guts alone. That’s where Reiko Kasahara comes in. She offers the milk of human kindness, literally, when she pulls out her boob for a shot of mammary juice. It’s the Japanese actress’s only skin onscreen, so milk it for all it’s worth.
