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.
Greater East Asia Co-Prosperity Sphere
To combat the protectionist dollar and sterling zones, Japanese economic planners called for a "yen bloc".
Japan's experiment with such financial imperialism encompassed both official and semi-official colonies. In the period between 1895 (when Japan annexed Taiwan) and 1937 (the outbreak of the Second Sino-Japanese War), monetary specialists in Tokyo directed and managed programs of coordinated monetary reforms in Taiwan, Korea, Manchuria, and the peripheral Japanese-controlled islands in the Pacific. These reforms aimed to foster a network of linked political and economic relationships. These efforts foundered in the eventual debacle of the Greater East-Asia Co-Prosperity Sphere.
