"Wichita" was assigned to the occupying force shortly after the end of the war. She departed Okinawa on 10 September for Nagasaki, arriving the following day as part of Task Group 55.7. "Wichita" was one of the first major warships to reach Japan; she was escorted by a destroyer, a pair of destroyer escorts, two minesweepers, and the hospital ship . "Wichita" was transferred to Sasebo on 25 September for four days before she returned to Nagasaki on 29 September. She returned to Sasebo shortly thereafter, and while she was there, a severe typhoon struck the area on 9–11 October. "Wichita" was not damaged during the storms. While at Sasebo, "Wichita"s crew inspected the Japanese ships and harbor installations to ensure Japanese compliance with the terms of surrender.
