he main focus is on the 5 member band of a small circus as it runs into problems while touring rural Japan. It also pays lots of attention to the two daughters of the aging and irascible ringmaster-circus owner. The high points are the sound (and score) and cinematography featuring a lot of vertiginous panning (appropriate - as high wire trapeze artists are also an important element in the film). A fascinating side-light on 30s Japan.
