Since the film was produced through the commissioning of the U.S. side, each edition was composed in English. An explanatory manuscript was created in Japanese first and then translated into English. The English translation was created by employees of the Japan Film Corporation with the cooperation of Toshiro Shimanouchi of the Ministry of Foreign Affairs and Yoshio Nishina.
