Hanagasa dochu

In this film, Hibari plays a dual role as brother and sister. The story involves a journey to Hanagasa for an incognito Lord (Kotaro Satomi) to overthrow an attempted usurpation of his domain, while being harassed by vassals of the usurper (Kensaku Hara). There's also a mysterious ronin played by Jushiro Konoe. The songs are seamlessly woven into the narrative and don't overwhelm the action. While the plot is derivative it is good example of its type and quite enjoyable. Note that there are some flashback sequences in black and white.
