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.
Aftermath of the 2011 Tōhoku earthquake and tsunami
The Japanese yen soared against most major currencies following the earthquake and reached a post-World War II high of 76.25 yen to the US dollar on speculation that Japanese investors would repatriate assets to pay for rebuilding. Since Japan relies heavily on exports, the strong yen could dampen its economy further. The financial markets' instability prompted the G7 to meet on 17 March, resulting in an agreement on joint forex intervention to sell yen against the dollar; it was the first such move since 2000.
