"Tama" remained on guard duty at Kataoka for over a month and then was sent to Maizuru Naval Arsenal for a refit on 4 May. She was thus absent during the "American Operation Landcrab" to retake the Aleutian Islands, and during Japanese evacuation of Kiska on 19 May. Returning to Kataoka only on 23 May, "Tama" resumed guard duties until 5 July. During "Operation Ke-Go" (the evacuation of Kiska) on 7 July, "Tama"s engines were considered too unreliable for her to participate directly in the evacuation, and she remained behind at Paramushiro. In any event, the mission was aborted due to weather. "Tama" remained on guard duty in the Kuriles until 30 August.
