Vice Admiral Jisaburō Ozawa, commander of the Third Fleet, hoisted his flag aboard the ship on 6 December. On 30 December "Ōyodo" participated in an operation to reinforce the garrisons at Rabaul and Kavieng. While returning to Truk on 1 January 1944, "Ōyodo" was slightly damaged by US aircraft from two aircraft carriers of Task Group 50.2, with two crewmen killed and six wounded. The following day, she rescued 71 survivors from the transport "Kiyosumi Maru", which had been torpedoed by an American submarine. "Ōyodo" returned to Yokosuka on 16 February following the successful American invasion of Kwajalein, and loaded torpedoes and supplies for the Japanese garrison at Saipan, which were delivered on 22 February.
