While not expecting much from this movie and mainly watching it to see the Kyoto International Conference Center, it was in fact a whole lot worse than expected: An embarrassing 80s' American fantasy version of Japan full of the worst cliches and stereotypes in the manner of Karate Kid, etc. Two stars for the architectural setting though.
While I found it worth the time watching this documentary, I agree with Gordon-11's criticism. An additional, if minor, shortcoming is the choice of country music as background music in a documentary with this theme and setting.
This movie is nothing but a long string of cliches, gangster movie cliches, feel-good movie cliches, etc. This may sound interesting, but as the movie isn't doing anything with these cliches other than - most likely unintentionally - being made up of them, it's not.
