1 Yen British Commonwealth Occupation Force

The British Commonwealth Occupation Force (BCOF) arrived in Japan in early 1946 to oversee the Allied occupation alongside American forces. Australia contributed the largest non-American contingent, and the Australian Army Canteen Service issued its own scrip to restrict spending to authorized facilities and keep occupation personnel out of the civilian Japanese economy — a policy driven partly by concern over black market activity and currency manipulation.

Miller, Freeman & Co. of Melbourne handled the print run. The paper is notably thin by Australian commercial printing standards of the period, and the notes are prone to horizontal fold breaks along the center — a condition issue collectors encounter frequently with this series.
