Korean currency
The yen was the currency of Korea during the Colonial rule, from 1910 to 1945, and was issued by the Bank of Joseon It was equivalent to the Japanese yen and consisted of Japanese currency and banknotes issued specifically for Korea. It was replaced by the South Korean won at par in 1945, and by the North Korean won in 1947.
North Korean won
Pictures of the new notes were published on December 4, 2009, in the "Chosun Shinbo", a North Korean newspaper based in Japan. The paper claimed that the measure would weaken the free market and strengthen the country's socialist system. However, the won plummeted 96 percent against the U.S. dollar in the ensuing days after revaluation. Authorities eventually raised the limit to 500,000 won, Chosun said, and promised no probe into savings of up to one million won and unlimited withdrawals if savings of more than one million are properly explained.
