Help Japanese banknote?

Hello everyone
What's it? It's a banknote? It's a bond? It's a ticket? I need help.
Regards.

Seems like a bond to me from the lettering on the back, issued in wartime Japan (Dai Nippon Teikoku means it was most likely printed before Japan's surrender) (Showa 19 = 1945/6), for 50 Yen.

Thank you very much.
I think the same as you, but I did not find any information to confirm or discard.
Regards.

​Showa 19 = 1944, and the denomination is 50 Sen.
