Japanese cruiser Izumo
1898 Izumo-class armored cruiser

Izumo (出雲; sometimes transliterated Idzumo) was the lead ship of her class of armored cruisers (Sōkō jun'yōkan) built for the Imperial Japanese Navy (IJN) in the late 1890s. As Japan lacked the industrial capacity to build such warships itself, the ship was built in Britain. She often served as a flagship and participated in most of the naval battles of the Russo-Japanese War of 1904–1905. The ship was lightly damaged during the Battle off Ulsan and the Battle of Tsushima. Izumo was ordered to protect Japanese citizens and interests in 1913 during the Mexican Revolution and was still there when World War I began in 1914.
She was then tasked to search for German commerce raiders and protect Allied shipping off the western coasts of North and Central America. The ship assisted the armored cruiser Asama in early 1915 when she struck a rock off Baja California. In 1917, Izumo became the flagship of the Japanese squadron deployed in the Mediterranean Sea. After the war, she sailed to Great Britain to take control of some ex-German submarines and then escorted them part of the way back to Japan.
The ship spent most of the 1920s as a training ship for naval cadets and became flagship of the IJN's China forces in 1932 during the First Shanghai Incident.
