My missus, who is Japanese, tells me that Raizo Ichikawa was a very big star around the time this film was made. Well, I can't say he does much for me. In fact, I think his mostly minimal acting style is one of the reasons that this film, first of a trilogy, is fairly uninteresting.
The effeminate yet deep-voiced Raizo plays a swordfighter with superb skills in the slashing department but minimal skills in relationships. A lot more could have happened than actually did, and it took quite a long time about it. The main enjoyment of this picture is some of the great costumes, period interior decorating and architecture and scenery. The other two films are better, but only slightly.
