Seven specimens of fishes and three specimens of crabs were collected with drifting algae by T/S Oshoro-maru from off the Pacific coast of Tohoku region, northern Japan. In fishes, a single specimen was identified as Histrio histrio (Linnaeus, 1758), five specimens as Oplegnathus punctatus (Temminck and Schlegel, 1844) and a single specimen as Stephanolepis cirrhifer (Temminck and Schlegel, 1850). In crabs, except a single specimen of megalopa, a single specimen was identified as Guinusia dentipes (De Haan, 1835) and a single specimen as Portunus (Portunus) sanguinolentus sanguinolentus (Herbst, 1783). Because previous northernmost records of P. (P.) sanguinolentus sanguinolentus were reported from Boso Peninsula in the Pacific Ocean and Akita Prefecture in the Sea of Japan, the present specimen represents the northernmost record of the species in the Pacific Ocean.
