| Comments |
The "A" prefix on these notes — giving rise to the collector nickname "A-Note" — distinguished US Military Yen issued under occupation authority from Bank of Japan currency still circulating simultaneously in 1945. Both were legal tender at par, which created immediate arbitrage problems: Japanese civilians and demobilized soldiers quickly learned to convert military yen into BOJ notes before remittances abroad could be traced or blocked.
The series was printed by the Bureau of Engraving and Printing before the surrender and shipped in bulk. Japan's occupation administration eventually suppressed the dual-currency arrangement in 1948, but not before significant quantities of A-Notes had drained into informal currency markets.
