After finishing overhaul, "Savo Island" began a transport mission from San Diego to Pearl Harbor, before transiting back to Alameda, California, on the West Coast. On 6 August, she departed for the Aleutian Islands, arriving on 15 August, right as the Surrender of Japan was announced. On 31 August, she headed, along with six other escort carriers, to support the occupation of Japan in northern Honshū and Hokkaidō. After finishing her duties, she returned to Pearl Harbor on 25 September, where she was assigned to the "Magic Carpet" fleet, which repatriated servicemen from throughout the Pacific. She first loaded occupation troops bound for Japan at San Francisco, before heading west. "Savo Island" made a total of three "Magic Carpet" voyages, repatriating troops from Guam, Pearl Harbor, and Okinawa, respectively. Upon arriving at Seattle on 14 January 1946, and finishing her final voyage, she transited to the Eastern seaboard, entering Boston Harbor on 16 March for inactivation.
