The Japanese, however, agreed to capitulate on 15 August, and "Bosque" departed Subic Bay on 27 August carrying occupation troops to Japan. She arrived in Tokyo Bay on 2 September, the day the formal surrender document was signed on board . The attack transport remained in Japan only two days, getting underway on 4 September to return to the Philippines. She arrived at San Pedro Bay, Leyte, on 11 September and, for the next two weeks, visited several Philippine ports. On 22 September, the ship embarked upon another voyage to the Ryukyus. She arrived at Buckner Bay, Okinawa, on the 25th and operated from that port until early October. On the 3d, "Bosque" departed Okinawa with Japan-bound occupation troops embarked. The attack transport arrived at Iyo-nada, Japan, on 5 October and, on October 6, moved to Aki Nada where she disembarked the troops. She departed Japan on 11 October and headed south—first to the Russell Islands and thence to Nouméa, New Caledonia. From Nouméa, she shaped a course back to the United States on 26 October.
