Central China (Japanese occupied region)

aka the Shanghai and Nanking or Nanking and Shanghai region.

Under a truly strange arrangement, the Nationalist government continued to operate the postal system in this occupied region although with a few Japanese and collaborator officials in place in Central China. Its stamps were only valid in the Central China region; the currency used was different from that used in Nationalist China. The local currency was originally valued the same as the Nationalist one, but higher inflation of the puppet government currency caused the creation of the various surcharged issues.
