The Berrien cruised offshore for about a week, waiting orders to proceed to Hagushi to unload her cargo.

While en route, Berrien encountered a mine and had near misses by 4 torpedoes fired by a Japanese submarine.

[citation needed] From Okinawa, she sailed back to Saipan, and received orders to head to the South Pacific.

Berrien returned to the Pacific and headed to Manila, then to Aomori, Japan as part of the initial allied landings in northern Honshu.

From there, she steamed north to Otaru, in Hokkaidō, northernmost of the main Japanese home islands, for another initial landing on Nippon soil.

There were not enough volunteers to man the ship, so she received orders to sail from Otaru into Tokyo Bay to take on Marines and Sailors returning home.

She was decommissioned in May 1946, returned to the United States Maritime Commission on 12 August 1947, and placed in the Suisun Bay Reserve Fleet.
