Following the IWC Resolution 2001-3, 2004-1 and 2005-3, this paper presents most recent status of conservation and research on the western gray whale conducted by Japan. In total of three POP sightings have been reported from the coast of Japan. Two sightings of gray whales were reported from the coast of Ishikawa and Fukui prefecture, in the Sea of Japan, which were eventually identified as an identical animal. Another sighting was reported from Miyake island, one of the Izu archipelago, in the North Pacific. One stranding occurred in Kanagawa prefecture. No anthropogenic mortality due to entanglement has been reported from the adjacent waters off Japan during the period from May 2018 to April 2019.
