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.
Currency intervention
By 2014, critics of Japanese currency intervention asserted that the central bank of Japan was artificially and intentionally devaluing the yen. Some state that the 2014 US-Japan trade deficit — $261.7 billion — was increased unemployment in the United States. Bank of Korea Governor Kim Choong Soo has urged Asian countries to work together to defend themselves against the side-effects of Japanese Prime Minister Shinzo Abe's reflation campaign. Some have (who?) stated this campaign is in response to Japan's stagnant economy and potential deflationary spiral.
In 2013, Japanese Finance Minister Taro Aso stated Japan planned to use its foreign exchange reserves to buy bonds issued by the European Stability Mechanism and euro-area sovereigns, in order to weaken the yen. The U.S. criticized Japan for undertaking unilateral sales of the yen in 2011, after Group of Seven economies jointly intervened to weaken the currency in the aftermath of the record earthquake and tsunami that year.
