to patrol in an area of the North Pacific Ocean south of Amukta. She completed her patrol on 14 December and arrived at Paramushiro in the Kuril Islands on 20 December 1942. On 25 December 1942, I-35 set out from Paramushiro on another supply run to Kiska, calling there briefly on 31 December 1942 to discharge her cargo before moving to a patrol area in the Bering Sea northeast of Adak Island. On 7 January 1943, she received orders to divert to an area in the Bering Sea northeast of Attu to search for American cruisers that Japanese forces had sighted there. She did not find them, and on 10 January 1943 she moved to a patrol area in the North Pacific Ocean south of Kiska. She visited Kiska from 17 to 18 January, then got back underway to patrol in the North Pacific south of Kiska and Amchitka. The light cruiser and destroyer steamed through her patrol on their way to Kiska carrying supplies and sighted what they thought was an American submarine on 23 January 1943, raising a concern that their supply mission had been compromised and prompting them to abort it and return to base, not realizing until later that the submarine they sighted probably was I-35. I-35 moved to a new patrol area north of Constantine Harbor on Amchitka on 30 January 1943, and on 14 February 1943 visited Kiska to embark a staff officer of the North Sea Defense Force and transport him to Attu. After completing her patrol, she eventually returned to Japan. On 27 March 1943, I-35 departed Yokosuka. She arrived at Paramushiro on 1 April 1943 and was reassigned to Submarine Division 15 in the Northern Force that day. She got underway from Paramushiro on 3 April 1943 for her third supply run to Kiska, which she visited on 8 April to unload four tons of cargo and disembark staff officers of the 51st Base Force. She departed Kiska the same day and reached Paramushiro on 13 April 1943. I-35 departed Paramushiro on 16 April 1943 to make her first supply run to Attu, where she delivered supplies and ammunition and disembarked several Imperial Japanese Army staff officers on 20 April 1943 before getting back underway the same day to return to Paramushiro, which she reached on 24 April 1943. She put to sea again on 27 April 1943 for her fourth
