I was reading a book about Chinese and Japanese traditional religion and this film was mentioned as having authentic elements, so I gave it a go.
In a fairly typical story we follow Raizo who has been trained brutally in a Ninja school since he was a kid. We follow him in these early days of harsh training and in the present time as an unconquerable fighter gone rogue. I do not think I need to say that he is out for revenge on his former master and that he former fellow students are after him to get rid of the problem.
The film is not too bad.
