Japanese 5 Yen Banknote, Specifically Belonging To The "A Series 1946 Post War

Japanese 5 Yen banknote, specifically belonging to the "A series" issued during the Shōwa era (Emperor Hirohito's reign, 1926-1989).
Here's more information about this note:
Issuance Period: Notes from the "A series" of the 5 Yen were issued between 1946 and 1955.
Design Features: The banknote features a colorized pattern on both sides, and it's also referred to as "Saibun 5-yen" (彩文5円).
Legal Tender Status: While these notes are still considered legal tender in Japan, they are rarely used in circulation today as their collector's value typically exceeds their face value.
Historical Context: The "A series" was introduced as a part of the "new yen switching" (新円切替) initiative after World War II to address the rampant inflation and devaluation of the yen.
Security Features: Notably, these notes were poorly made due to post-war conditions and initially lacked watermarks, making them prone to counterfeiting upon their release in 1946.
