Question: When Chozen, while bullying Daniel, takes the latter's handheld drum (which Chozen mockingly called a "baby rattle") and calls the latter a baby, Kumiko, sticking up for Daniel, fiercely says a phrase in Japanese (or Ryukyuan) to Chozen. What exactly does Kumiko say, and what does it mean?
Question: Throughout the film, are there a series of deliberate 'Back to the Future' references? I noticed two straight away - Daniel says 'If you put your mind to it anything is possible, you can do anything' which is repeated several times during BTTF. Also, when Daniel and Kumiko are at the dance, the song 'Earth Angel' can be heard. The song at the climax of the dance in BTTF. Are these deliberate, as BTTF was a year before this movie?
Question: If the crane kick is done correctly and no one can defend against it, why didn't it work in the fight against Chozen?
Question: Is the tea ceremony a real tradition or was it made up for the movie?
