The chart below provides a full summary of all applying exchange-rate regimes for EU members, since the European Monetary System with its Exchange Rate Mechanism and the related new common currency ECU was born on 13 March 1979. The euro replaced the
Japanese currency rate of three ""Bu"". They were called "Aratame Sanbu Sadame" (改三分定, "Fixed to the value of three "bu""). Meanwhile, local governments issued their own currency chaotically, so that the nation's money supply expanded by 2.5 times between 1859 and 1869, leading to crumbling money values and soaring prices. The system would be replaced by a new one, after the conclusion of the Boshin War, and with the onset of the Meiji government in 1868. Following 1868, a new currency system based on the Japanese yen was progressively established along Western lines, which has remained Japan's currency system to this day.
