Input: Consider Input: 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.

Input: Consider Input: Question: How much time had passed between PlayStation 3's Japanese release and Suda's first horror title that sold well on PlayStation 3? Passage:The game's history can be traced back to 2005, when Goichi Suda and Shinji Mikami (creator of the Resident Evil series) became good friends while working together on Killer7. Suda wanted to make a survival horror game exclusively for the PlayStation 3. With his first horror title  receiving decent sales in Japan by 2006, Suda immediately began working on Kurayami (Japanese for 'Darkness') in his spare time. It was at one time thought to be called "Closer". However, EA later confirmed that name had been abandoned for another title. By the Electronic Entertainment Expo (E3) in 2006, a publisher for Kurayami had not yet been established. In 2008, Suda presented the game's concept to EA Games, who agreed to license the Unreal Engine 3 and to publish the game to a worldwide audience. Shinji Mikami was then invited to executive-produce the project. Suda wanted to announce the game at E3 2009, but was not allowed to do so, due to a media silence agreement between Grasshopper Manufacture and EA Games. That December, Akira Yamaoka (sound designer for the Silent Hill series) left Konami after finishing his work on  and joined Grasshopper Manufacture because he enjoyed the latter's game No More Heroes. Yamaoka began work as the sound designer for the game. The game went about five different versions until Electronics Arts approved it. The newly titled Shadows of the Damned was finally unveiled at the Tokyo Game Show in 2010 as an action game.
