[Q]: Question: What year was the treaty that opened up the Korean Peninsula to Japanese trade signed? Passage:Un'yō  was one of the ships dispatched to Kyūshū in 1874 during the Saga Rebellion. In May 1875, she carried diplomats to Busan in Korea in an attempt by the Japanese government to open diplomatic relations with the Joseon dynasty government. After they were rebuffed in these negotiations, the Japanese government again dispatched Un'yō in September 1875 under the command of Inoue Yoshika to provoke a military response, in what was later termed the Ganghwa Island incident. This eventually led to the Treaty of Ganghwa, which opened the Korean Peninsula to Japanese trade. In 1876, Un'yō  was assigned to assist in the suppression of the Hagi Rebellion, another uprising of disaffected former samurai. Un'yō  was severely damaged when she ran aground off the coast of the Kii Peninsula, and was scrapped the following year.
