This movie was based on the hit song "Kaette kita yopparai" by The Folk Crusaders, a folk and pop music group that also appeared in the film. It was released in March 1968.

I had to watch this film two tmes (and it repeats the movie twice in one playing, with a slight "twist" in the second run-through) before I go the point being made..

After I realized what it was trying to say, it became a lot clearer and it made sense then.

My late brother, James Vernon Robinson, was stationed in Japan with the U S Navy as a security/intelligence NCO in the 1960s-early 1970s; he always said that unless you has a hockie mask on, carrying a chain saw dripping with blood, that passing through Japanese customs was simple and quick, if you weren't carrying a Korean passport...but, if you were carrying a Korean passport, you were placed under a bright lamp and interrogated for hours or days as to your past lives, income, et al (hyperbole, but you get the meaning!) before the Japanese allow you, as a Korean, to enter their country!

This film sheds the same paradigm, but in a more humorous way!

This film would probably be more enjoyed by young people, because of the silly song associated with it, although it does have an overall message.

Re-watch, probably not!
