i think this may be some sort of rations paper I’m not sure. I tried to use a photo interperter but it didn’t work very well. Any help would be appreciated.
This is not a banknote, or any sort of currency at all; it's actually a primary school ("小學校") certificate from Japan (as evidenced by the Hiragana characters accompanying the Kanji).
The Kanji characters I can identify indicate that it was issued by a primary school in Tokyo in the 11th Year and 3rd month of Emperor Showa's reign (1937).
