was the lead ship of the two Katori-class pre-dreadnought battleships built in the first decade of the 20th Century, the last to be built by British shipyards for the Imperial Japanese Navy (IJN). Ordered just before the start of the Russo-Japanese War of 1904–05, the ship was completed a year after its end. She saw no combat during World War I, although the ship was present when Japan joined the Siberian Intervention in 1918. Katori was disarmed and scrapped in 1923–25 in accordance with the terms of the Washington Naval Treaty of 1922.
