"Hyūga" and the rest of the 2nd Battleship Division set sail on 28 May with the Aleutian Support Group at the same time most of the Imperial Fleet began an attack on Midway Island (Operation MI). Commanded by Vice-Admiral Shirō Takasu, the division was composed of Japan's four oldest battleships, including "Hyūga", accompanied by two light cruisers, 12 destroyers, and two oilers. Official records do not show the division as part of the larger Midway operation, known as Operation AL; they were to accompany the fleet under Admiral Isoroku Yamamoto, but were only to provide support to the Aleutian task force if needed.
