In June 2024, five subadult male Hemigrapsus takanoi Asakura & Watanabe, 2005 were collected from the Sagami River estuary, Kanagawa Prefecture, located on the eastern side of the middle Honshu Island, Japan. The species has been known from subtropical to subarctic regions along the Pacific coast of East Asia (from East China to Far East Russia) and along the Northern European coast (from Northern Spain to Northern Germany). This is the first specimen-based record for the species from the Sagami River.
