During the youngest days of the Qing dynasty paper money was used but this was quickly abolished as the government sought not to repeat history for a fourth time; however, under the reign of the Xianfeng Emperor, due to several large wars and rebellions, the Qing government was forced to issue paper money again.
Japanese military currency (日本軍用手票) is the name given to money used by the Japanese armed forces for the purchase of supplies in occupied territories. It was mainly issued in denominations of yen, and subsidiary currency of sen with the exception of the first Sino-Japanese War series. This particular article covers pre-Shōwa era currency issued from 1894 to 1918 in three different periods. During this time Japan was militarily involved in the First Sino-Japanese War, Russo-Japanese War, and events during World War I such as the Siberian intervention. The military currency issued during these events circulated in Japanese Korea, the Republic of China (Manchuria), and the Russian State. All of the notes issued share a similar design which resembles government issued civilian currency which circulated in Japan from 1872 to 1899. Japanese military currency was exchangeable at the given time for both silver and gold bullion. Most of these events were not long term which impacted the amount of surviving currency in different ways. It was also routine after each event for officials to exchange the military currency issued for bullion or other forms of payment such as banknotes. Unredeemed notes were thus either held by the public as commemorates or eventually lost in the decades that followed. Those that remain today are collected and traded depending on the condition and surviving rate of the series.
