Three days later, the "Auburn" got underway for Nagasaki. While there, she played an important part in establishing ship-to-shore communications and arranging facilities for occupation troops. On 25 September, she arrived at Wakayama, Japan, and began assisting forces in the occupation of Osaka, Kyoto, and several other cities to the north. In early October, she moved to Yokohama. Her occupation duty ended on 12 October, when she left Japanese waters and headed back to the West Coast of the United States.
