written to  suit the Japanese setting. A 10 day shooting schedule was planned, and the  studio shots were completed in 7 days, with only the closing exterior shot  remaining. Weather only allowed that shot to be wrapped three days later. The  film was shown in the Mormon Pavilion at Expo 70. Attendance over 6 months  tallied at 6,658,532 visitors, and the film was also shown elsewhere in  cultural halls for those who could not get into the pavilion.
