Just took a photo of my 1000 JPY note, you can see all parts of it even the unique sign.
Yen, monetary unit of Japan. The yen was divided into 100 sen and into 1,000 rin until 1954, when these tiny denominations were removed from circulation. Despite having suffered enormous devastation during World War II, Japan enjoyed an economic miracle in the second half of the 20th century, during which time the yen became one of the leading international currencies, challenging the pound sterling and the dollar on international markets. The yen’s symbol is ¥. The name yen derives from an ancient term for Chinese round coins (yuan).
