The hwan (Korean: 환) was the currency of South Korea between February 15, 1953, and June 9, 1962. It succeeded the first South Korean won and preceded the second South Korean won.
The Old Taiwan dollar was in use from 1946 to 1949, beginning shortly after Taiwan's handover from Japan to the Republic of China. The currency was issued by the Bank of Taiwan.

The yen was the currency of Korea, Empire of Japan between 1910 and 1945. It was equivalent to the Japanese yen and consisted of Japanese currency and banknotes issued specifically for Korea.

The mun was introduced as the main currency of Korea in 1625 and stayed in use until 1892. Prior to the mun, cash coins with the inscriptions tongbo (通寶) and jungbo (重寶) and silver vases called ŭnbyŏng were used as currency in the Goryeo Dynasty (918–1392), as well as imported Chinese currency. The mun resembled and was derived from the Chinese wén. Coins denominated in mun were cast in copper-alloys such as brass or bronze and were round with square holes. From the 17th century until the end of the 19th century, coins denominated in mun bearing the inscription Sangpyeong Tongbo, introduced in 1633, were the most widely circulated currency. In 1888, coins were struck in small numbers denominated in mun and won. The mun was replaced in 1892 when the yang was introduced.
The won is the currency of both North and South Korea. "Won" is a cognate of the Chinese currency unit, the yuan, and the Japanese currency unit, the yen, meaning "round object". The won is subdivided into 100 jeon.

Japanese currency has a history covering the period from the 8th century AD to the present. After the traditional usage of rice as a currency medium, Japan adopted currency systems and designs from China before developing a separate system of its own.
Korean currency dates back as far as the Goryeo dynasty (918–1392) when the first coins were minted. The coins, cast in both bronze and iron, were called tongbo and jungbo. Additionally, silver vases called ŭnbyŏng were widely used and circulated as a currency among the aristocracy of Goryeo.
The 5 sen note (五銭紙幣) was a denomination of Japanese yen that was issued nonconsecutively from 1944 to 1948 in paper form. Five sen notes were worth one-twentieth of a yen, making them the lowest subsidiary yen banknote ever made. These notes are broken up into two types, which were issued before and after World War II. Those issued before the war filled a void left when 5 sen coin production became difficult. The second and final issue came after the war when the Japanese government tried unsuccessfully to curb inflation. Neither of these notes are currently legal tender as the "sen" was abolished in 1953 when the yen system was modified to exclude the old fractional currency. These banknotes are now easily collectable and affordable as they were issued in large amounts.
The 10 sen note (十銭紙幣) was a denomination of Japanese yen issued in four different series from 1872 to 1947 for use in commerce. Meiji Tsūhō notes are the first modern banknotes issued after Japanese officials studied western culture. There circulated alongside ten sen coins until their withdrawal in 1887. The other three series of ten sen notes issued are in some way tied to the impacts of World War I and World War II. Taishō fractional ten sen notes were issued as a response to a coin shortage that was caused by the first of these wars. They were eventually suspended in the early 1920s when things had settled down, and were later demonetized in 1948. The last two series of ten sen notes were issued by the Bank of Japan rather than the treasury. First series notes were issued as ten sen coins could no longer be produced, while the A series was released after the war in a futile attempt to curb inflation. These last two issues were demonetized at the end of 1953 when the Japanese government passed a law abolishing subsidiary notes in favor of the yen. Ten sen notes are now bought and sold as collectors items depending on condition.
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.
