The Ise-class battleships were a pair of dreadnought battleships built for the Imperial Japanese Navy (IJN) during World War I. Both ships carried supplies for the survivors of the Great Kantō earthquake in 1923. They were modernized in 1934–1937 with improvements to their armour and machinery and a rebuilt superstructure in the pagoda mast style. Afterwards they played a minor role in the Second Sino-Japanese War.

Operation Kita was conducted by the Imperial Japanese Navy (IJN) during the Pacific War in February 1945. Its purpose was to return two Ise-class hybrid battleship-aircraft carriers and four escort ships to Japan from Singapore, where they had been based since November the previous year. The movement of the Japanese force was detected by the Allies, but all attempts to attack it with submarines and aircraft failed. Nevertheless, as a result of the intensifying Allied blockade of Japan, the Ise-class battleship-carriers and their escorts were among the last IJN warships to safely reach the country from the Southwest Pacific before the end of the war.
