Toi (,
twoy) meant "barbarian" in
Middle Korean. The Toi pirates sailed with about 50 ships from the direction of
Goryeo, then assaulted
Tsushima and
Iki provinces, beginning on 27 March 1019. After the
Iki Island garrison, consisting of 147 soldiers led by Fujiwara Noritada, was wiped out, the Jurchen slaughtered all the men while seizing women as prisoners. Fujiwara Noritada, the governor, was killed. Subsequently, the Jurchen raided the Ido, Shima, and Sawara counties of
Chikuzen Province and, on April 9, attacked
Hakata (now a ward of the city of
Fukuoka). For a week, using in
Hakata Bay as a base, they sacked villages and kidnapped over 1000 Japanese, mostly women and young girls, for use as slaves. The
Dazaifu, the administrative center of Kyūshū, then raised an army and successfully drove them away. After that, they then raided Matsuura county in
Hizen Province from April 13 to May 20, and were eventually repelled by Genchi, the founder of the "Matsuura 48 Parties", and after attacking Tsushima again, they retreated towards the Korean Peninsula. A few months later, the Goryeo delegate Jeong Jaryang () reported that the
Goryeo Navy had intercepted the Jurchen off of
Wonsan and eliminated them. They rescued around 300 captives, who were "provided white clothes and fed meals with silverware" by the Goryeo government. Goryeo then repatriated them back to Japan, where they were thanked by the Dazaifu and given rewards. There remain detailed reports by two captive women, Kura no Iwame and Tajihi no Akomi, with Kura no Iwame's report transcribed. The children and women kidnapped by the Jurchen were most likely forced to become
sex slaves. Only 270 or 259 Japanese on eight ships were returned when Goryeo intercepted them. 1280 were taken prisoner, 374 were killed, and 380 livestock were killed for food. The Jurchen lived in
Hamgyong Province, now in
North Korea. Traumatic memories of the Jurchen raids on Japan and the
Mongol invasions of Japan, in addition to the adoption of the
Hua–Yi distinction, contributed to Japan's antagonistic views toward the Jurchen and, later, the
Manchu. For example,
Tokugawa Ieyasu viewed the
Later Jin of the Jurchen as a threat. The Japanese mistakenly believed that Yezo (now
Hokkaido) had a
land bridge to the Jurchen homeland, and therefore thought they could invade Japan by land. In 1627, the
Tokugawa shogunate sent a message to
Joseon via Tsushima, offering help to Joseon against the
Later Jin invasion of Joseon. However, Joseon refused. During
Toyotomi Hideyoshi's
Imjin War, the
Hamgyong campaign was a direct invasion of Jurchen-controlled territory from conquered Joseon. == See also ==
