Excellent! I just saw this at the SF Asian American Film Festival. Apparently, there is only one print in existence and no VHS or DVD releases. I hope that you are as lucky as I was and get an opportunity to see it.
The lead, Shigeta, was at the screening and spoke a few words to the audience and answered some questions. He got a standing ovation. I was glad that he is still sharp and articulate.
The good:
1) James Shigeta is outstanding. He's handsome and skilled. He plays Terasaki with passion and sophistication.
2) It's a view of WW2 from the Japanese side, which is all too rare.
3)It's based on a true story, which makes the film resonate even more.
4) The dialogue is wonderful. The opening scene is written and acted with a lot of wit which had the audience laughing.
5) It was produced in 1961. Unlike many Hollywood films of the time, Asians have a reasonably accurate portrayal and not just crude caricature (e.g. "Breakfast at Tiffany's").
The bad:
1) The film is set in the 1930s and 40s but the costuming and furnishings are straight out of 1960. I'm a bit of a vintage clothing geek so this was jarring.
