The Izumo class or armored cruisers was one of six armored cruisers ordered to overseas shipyards after the First Sino-Japanese War as part of the Six-Six Program (six battleships - six cruisers) intended to be the backbone of the Imperial Japanese Navy. Although very similar to the Asama-class cruisers Asama and Tokiwa, its differences are significant enough to classify it as the lead ship in the separate Izumo class, which also included its sister ship, the Iwate.

The Izumo was an armored cruiser of the Imperial Japanese Navy. It was built in Elswick, Great Britain by Armstrong Whitworth. The Izumo served an important role in the Russo-Japanese War. In World War I, the Izumo was used extensively for overseas patrol. Afterwards, the Izumo was assigned to the training fleet. It supported the Japanese invasion of China during the Second Sino-Japanese War. While in Shanghai on 8 December 1941, the Izumo forced the surrender of the American gunboat USS Wake and sunk the British gunboat HMS Petrel, in one of the first acts of the Pacific War following the attack on Pearl Harbor. For the duration of World War II, Izumo was used as a training vessel. The Izumo was sunk at dock in an American air attack on 24 July 1945, and its hulk was later raised and scrapped in 1947.
