Banknotes of the Japanese yen
The banknotes of the Japanese yen are part of the physical form of Japan's currency. The issuance of the yen banknotes began in 1872, two years after the currency was introduced. Throughout its history, the denominations have ranged from 0.05 yen to 10,000 yen.
Japanese military yen
In the late 1930s there was an issue of military yen which was similar to the standard yen in terms of design, but with minor modifications. Generally, thick red lines were overprinted to cancel the name "Bank of Japan" (日本銀行) and any text promising to pay the bearer in gold or silver. Large red text instead indicated that the note was military currency ("軍手用票") so as not to be confused with regular Japanese yen.
