Issued to commemorate the enforcement of the Tokyo Metropolitan Government System on July 1, 1943 (Showa 18). The Tokyo Metropolitan Government System integrated the former Tokyo Prefecture and Tokyo City, giving rise to the present-day Tokyo. The map was sold for twenty-five sen and was published by the Japan Control Map Corporation. It is a valuable historical document, being a publication from wartime. Found it among antiques. Other items are included as extras. For those who are interested, thank you.
