Amagi was a screw sloop, commissioned 4 April, 1878. Amagi was sent to Korea as a show of force in 1882, and in 1884, with one Tōgō Heihachirō in command, she became the first Japanese warship to ascend the Yangzi River, visiting the port at Wuhan. Later that year, Amagi and Tōgō served as observers during the Sino-French War. By the time of the Sino-Japanese War, Tōgō had moved on, but Amagi saw extensive combat, fighting in both the battles of Weihaiwei and the Yalu River. Amagi was redesignated as a second-class gunboat post-War, and assigned to coastal patrol duties. Despite a refit, Amagi was only used as a guard ship during the Russo-Japanese War, assigned to Yokohama. She was declared obsolete in June, 1905, and sold 24 November, 1908. Amagi was purchased by the Toba Shosen Gakkō maritime school, and used as a training ship, but disappeared from records. While she was probably scrapped, her disposal date is a mystery.
