"Torsk" cruised to Guam and then proceeded to Kii Suido in the Japanese home islands, arriving there on 11 May. While there, she patrolled for American air crews that had to bail out from damaged aircraft during their raids on Japan, but no aircraft went down in the area that day. Late on 11 May, she moved to the northeastern coast of Honshu, arriving two days later. Over the course of 14 and 15 May, she attempted to contact the submarine wolfpack operating in the area, and she finally rendezvoused with the submarines and the next day. She joined their patrols on the east coast of the island, but found no Japanese vessels in the area.
