B Yen (B圓, B en^?) was a colloquial term used to refer to a form of military scrip used in post-war US-Occupied Okinawa from April 15, 1946 to September 1958. Officially, it was called B type military scrip (B型軍票, B-gata gunpyō^?).

The B yen bills were of a blue or green color, and came in eight different denominations.

The designation "B type yen" derives from the fact that, for a time after the US occupation of Okinawa Prefecture began, following the end of World War II, the US military used a separate scrip called "A type yen" while "B type yen" were only used by the local civilians. In the brief time between the 1945 battle of Okinawa and the beginning of the US occupation, the islands went from a currency-free system, relying upon barter and distributions of supplies from the authorities, to the reintroduction of currency with the B yen, the introduction of the new Japanese yen (both "new yen" and "B yen" being used concurrently for a time) and then the establishment of the B yen as the only legal currency.

Beginning in 1948, the A type yen was deprecated, and B type yen came to be used by military and civilians alike.

Though the rest of Occupied Japan continued to use regular Japanese yen throughout the Occupation, military scrip was introduced in Okinawa because, even at that time, the US military government intended to continue occupation of Okinawa long after ending it in the Home Islands. Steps were taken to prevent inflation which would have resulted from the illegal influx of regular yen from the Home Islands, and once the economy in Okinawa was considered stable enough, the B yen was done away with, and the US dollar brought into use.
