During the Russo-Japanese War of 1904–05, Kasuga participated in the Battle of the Yellow Sea and was lightly damaged during the subsequent Battle of Tsushima. In addition, she frequently bombarded the defenses of Port Arthur. The ship played a limited role in World War I and was used to escort Allied convoys and search for German commerce raiders in the Indian Ocean and Australasia. Kasuga became a training ship in the late 1920s and was then disarmed and hulked in 1942 for use as a barracks ship. The ship capsized shortly before the end of World War II in 1945 and was salvaged three years later and broken up for scrap.
