After their departing British friend gives them silk in an early scene, Yusaku suggests making it into western-style clothes. Satoko warns that this will go against the new National Uniform Edict. A few scenes later, Yusaku leaves for a business trip to Manchuria. While he is away, Satoko hears on the radio that the Tripartite Pact has been signed with Germany and Italy. The radio makes clear that the date is September 27, 1940. However, the National Uniform Edict was not issued until over a month later, on November 2, 1940, meaning it would not have been in effect during the earlier scene with the silk.
