On 15 April, "Arcturus" received orders to Saipan where she was routed on to Pearl Harbor and San Francisco, arriving at the latter port on 18 May. After loading cargo and supplies, "Arcturus" returned to the western Pacific to resupply the troops advancing on Okinawa. After a brief stop at Eniwetok on 11 June, the cargo ship dropped anchor at Okinawa on 5 August. Enemy air attacks continued, but less frequently and with decreasing intensity. On 15 August, when Japan capitulated, "Arcturus" was still at Okinawa. She was then assigned to ferry occupation forces to Korea and China. On 5 September, the ship departed Okinawa in a convoy carrying Army troops and cargo to Jinsen, Korea. The convoy arrived at Jinsen on 8 September, and the occupation troops were joyfully received by the Koreans.
