Tsushima-Fuchū Domain

Tsushima Fuchū domain (対馬府中藩, Tsushima Fuchū han), also called the Tsushima domain, was a Japanese domain of Japan in the Edo period. It is associated with Tsushima Province in modern-day Nagasaki Prefecture.


In the han system, Tsushima was a political and economic abstraction based on periodic cadastral surveys and projected agricultural yields. In other words, the domain was defined in terms of kokudaka, not land area. This was different from the feudalism of the West.


The Sō clan was one of few daimyo clans during the Edo period which continued to control the same fiefs it controlled previously. Although it fought against Tokugawa Ieyasu at the battle of Sekigahara, the Sō clan was allowed by the shogunate to continue to rule Tsushima and entrusted it to diplomatic negotiations and trade with Joseon Korea. Its services included receptions of Korean missions to Japan. The Fuchū domain sold imports and bought exports in Osaka and Kyoto. It negotiated trade and diplomacy with the Nagasaki Commissioner in Nagasaki. It had an office in Busan where daily trade and diplomatic service were conducted.

The Fuchū domain was given the status of a 100,000 koku-class han although its real production was below 30,000 koku, on account of its important diplomatic status, and economic wealth as a result of trade with Korea. In the late 17th century, it prospered in Korean trade and with silver mines, but from the 18th century, it suffered from trade depression and depletion of silver ores. Its economic reforms and the shogunate's constant aid did not improve its finances. Increasing threats of Western imperial powers weighed heavily on the Fuchū domain. In 1861, a Russian naval ship occupied a port of Tsushima. What was worse for Tsushima was a growing internal conflict between pro- and anti-shogunate retainers. In 1862, it concluded an alliance with the Chōshū domain, which was one of the prominent leaders of the Sonnō jōi movement. But the anti-shogunate faction was purged in 1864. The loss of human resources prevented Tsushima from playing a significant role at the Meiji Restoration.

The last daimyo of Tsushima, Sō Shigemasa (Yoshiaki) became Governor of Izuhara Prefecture in 1869 and after the Abolition of the han system was given the title of Count (hakushaku) in 1884. The diplomatic service with Korea was taken over by the new Ministry of Foreign Affairs.
