Korean yen
The Korean yen was the currency of Korea between 1910 and 1945. It was equivalent to the Japanese yen and consisted of Japanese currency and banknotes issued specifically for Korea. The yen was subdivided into 100 sen. It replaced the Korean won at par and was replaced by the South Korean won and the North Korean won at par.

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.
