New User with Lots of Memorobilia from Grandfathers, so glad I found this forum! - First Post: Japanese Currency

[Tyshell7]

Hello everyone! My maternal grandfather served in WWII and took a 50 year vow of secrecy after the war about what he did specifically. Turns out, he worked on the Manhattan Project. My paternal grandfather served in the Navy as the war was coming to an end, he came back with a full chest of japanese wartime objects after the war. My family and I are very excited to learn more about these treasures!

First one: Japanese Currency (possibly invasion currency?)
