Japanese currency
Encyclopedia
Japanese currency has a history covering the period from the 8th century to the present. After the traditional usage of rice as currency medium, Japan's currency was characterized by an early adoption of currency systems and designs from mainland China

Embassy to the Tang court (630 CE)

Japan's contacts with the Chinese mainland became intense during the Tang period, with many exchanges and cultural imports occurring. The first Japanese embassy to China is recorded to have been sent in 630, following which Japan adopted numerous Chinese cultural practices.

The importance of metallic currency appeared to Japanese nobles, probably leading to some coin minting at the end of the 7th century, such as the Tomimotosen coinage (富元銭), discovered in 1998 through archaeological research in the area of Nara

 dated April 15, 683 CE mentions: "From now on, copper coins should be used, but silver coins should not be used", which is thought to order the adoption of the Tomimotosen copper coins.

First official coinage (708 CE)

Japan's first formal currency system was the Kōchōsen (Japanese: 皇朝銭, "Imperial currency"). It was exemplified by the adoption of Japan's first official coin type, the Wadōkaichin

 in 621 CE. The Wadokaichin had the same specifications as the Chinese coin, with a diameter of 2.4 cm and a weight of 3.75g.

Currency reform (760 CE)

The Wadōkaichin soon became debased, as the government rapidly issued coins with progressively lesser metallic content, and local imitations thrived. In 760 CE a reform was put in place, in which a new copper coin called Mannentsūhō (万年通寶) was worth 10 times the value of the former Wadōkaichin, with also a new silver coin named Taiheigenbō (大平元寶) with a value of 10 copper coins, as well as a new gold coin named Kaikishōhō (開基勝寶) with a value of 10 silver coins.

Last emissions (958 CE)

The Kōchōsen Japanese system of coinage became strongly debased, with its metallic content and value decreasing. By the middle of the 9th century, the value of a coin in rice had fallen to 1/150th of its value of the early 8th century.

By the end of the 10th century, compounded with weaknesses in the political system, this led to the abandonment of the national currency, with the return to rice

 as a currency medium. The last official Japanese coin emission occurred in 958, with very low quality coins called Kangendaihō (乾元大寶), which soon fell into disuse.

Importation of Chinese coinage

From the 12th century, the expansion of trade and barter again highlighted the need for a currency. Chinese coinage came to be used as the standard currency of Japan, for a period lasting from the 12th to the 17th century. Coins were obtained from China through trade or through "Wakō

Imitations of Chinese coinage

As the Chinese coins were not in sufficient number as trade and economy expanded, local Japanese imitations of Chinese coins were made from the 14th century, especially imitations of Ming coins, with inscribed names identical to those of contemporary Chinese coins. These coins were considered as very low value compared to Chinese coins, and several of them had to be exchanged just for one Chinese coin. This situation would continue until the beginning of the Edo period

, when a new system was put in place.

Local experiments (16th century)

The growth of the economy and trade meant that small copper currency became insufficient to cover the amounts that were being exchanged. During the Sengoku period, the characteristics of the future Edo Period system began to emerge. Local Lords developed trade, abolishing monopolistic guilds, which led to the need for large-denomination currencies. From the 16th century, local experiments started to be made, with the minting of local coins, sometimes in gold. Especially the Takeda clan of Kōshū minted gold coins which were later adopted by the Tokugawa Shogunate

Hideyoshi unified Japan, and thus centralized most of the minting of large denomination silver and gold coins, effectively putting in place the basis of a unified currency system. Hideyoshi developed the large Ōban

From 1601, Tokugawa coinage consisted in gold, silver, and bronze denominations. The denominations were fixed, but the rates actually fluctuated on the exchange market. Tokugawa started by minting Keicho gold and silver coins, and Chinese copper coins were later replaced by Kan’ei Tsuho coins in 1670.

The material for the coinage came from gold and silver mines across Japan. To this effect, gold mines were newly opened and exploited, such as the Sado

Bakumatsu currency (1854–1868)

Tokugawa coinage fell apart following the reopening of Japan to the West in 1854, as the silver-gold rates gave huge opportunities for arbitrage to foreigners, leading to the loss of large quantities of gold to exportation.

Foreign arbitrage

 led to a massive outflow of gold, as gold traded for silver in Japan with a 1:5 ratio, whether that ratio was 1:15 abroad. During the Bakumatsu period in 1859 Mexican dollars were even given official currency in Japan, by coining them with marks in Japanese and officializing their exchange 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 anarchically, 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

National Bank Act (1872)

The National Bank Act of 1872 led to the establishment of 4 banks between 1873 and 1874, until there were more than 153 national banks by the end of 1879. The national banks issued identically designed convertible notes, which were effective in funding the industry and progressively replaced government notes. In 1876, an amendment allowed the banks to make the banknotes virtually non convertible. These national banknotes imitated the design of American banknotes, although the name of the issuer was different for each.

Severe inflation broke out with the Seinan Civil War in 1877. This was controlled by the reduction of government spending and the removal of paper currency from circulation. During the Seinan Civil War, an original type of paper money was issued by the rebel leader Saigō Takamori
