Overview
A classic post-war Japanese 1 Yen note featuring the philosopher Ninomiya Sontoku, printed during the transition from imperial to modern Japan. It is distinguished by its blue reverse and the iconic 16-petal chrysanthemum crest of the Imperial House at the top center.
Story
Issued in 1946, this note was part of a desperate effort to stabilize Japan's economy after WWII. It features a peasant-sage who taught that small daily efforts lead to great change—a message for a nation in ruins.
Maker / Origin
The Bank of Japan issued this series under the supervision of the Allied Occupation (GHQ). The portrait is of Ninomiya Sontoku, a 19th-century agricultural reformer who became a symbol of Japanese resilience and work ethic.
Condition & Value
The note appears remarkably crisp with sharp corners and no visible heavy folds or staining. This 'About Uncirculated' condition significantly helps its collectibility, as most were heavily handled during the post-war inflation. While historically significant, millions were printed.
