I can tell you that it's in Chinese, and at the top it says "1 yuan".

The bottom also says "jun1 piao4", which means a military ticket, or probably scrip in this case.

However, Japanese tends to steal a lot from Chinese (they call it kanji, and the Chinese call it hanzi), so there's always some possibility that this could also be Japanese, although I'm skeptical of that possibility here.

And I suppose that I can also note that it uses the fancy version for 1, that is used for checks and currency, since the boring version for 1 is just a horizontal line, which is easily manipulated to be just about any amount for enterprising souls.

And in case you're wondering, the Chinese at the top and bottom reads from right to left, which is the traditional Chinese method of writing. Somewhat excitingly, historically they wrote from top to bottom, right to left, and the back of the book to the front, so very different than our approach. But more recently, they've adopted our approach to using left to right, top to bottom, and front of the book to the back of the book.
