"Toucan" returned to the Far East in the summer of 1954 and reached Incheon, Korea, on 14 August. Two days later, she got underway for the west coast of Korea and operated primarily in the Taeyongyong-Do and Tojang Po vicinity. She departed Sasebo on 11 January 1955 and proceeded to Hong Kong only to return to Japanese waters a fortnight later. Her stay at Sasebo was brief. Four days later, she weighed anchor for Keelung, Formosa, and thence moved to the Tachen Islands. On 7 February, the minesweeper took part in the evacuation of Chinese Nationalists from the Tachen group and disembarked the evacuees at Sasebo a week later. During this mission, on 7 February 1955, "Toucan" was redesignated MSF-387.
