Japan: Meiji Period woodblock print depicting the Naval Battle of the Yellow Sea (Yalu River)...

The First Sino-Japanese War (1 August 1894 - 17 April 1895) was waged between Qing Dynasty China and the Japanese Empire, primarily over control of the Korean peninsula. In China, the war is commonly known as the War of Jiawu, while in Japan it is called the Japan-Qing War, and in Korea, the Qing-Japan War. The war lasted 8 months altogether, and saw more than six months of unbroken victories and success by the Japanese land and naval forces against the numerically superior but militarily inferior Chinese army. The Japanese eventually took over the Chinese port city of Weihaiwei and forced the Qing government to sue for peace in February 1895, though the war would continue until April. The Sino-Japanese War highlighted the stark failure of the Qing Empire to modernise and advance its armed forces, and resulted in regional dominance in East Asia shifting for the first time from China to Japan. The Korean peninsula, Joseon, was removed from the Chinese sphere of influence and fell under Japanese vassalage instead.
