Two specimens of Trichiurus sp. 2 sensu Nakabo, 2000 were collected from eastern Sagami Bay, southern Japan, in November 2012 and January 2017. These specimens represent the first records from Sagami Bay, and the northernmost records for the species. The occurrence of T. sp. 2 from Sagami Bay in winter is attributed to transportation by the warm Kuroshio Current in summer or autumn, and suggests that survivability is affected by the development of a body of warm water.
