Nautiloid specimens identifiable as Aturia cubaensis were collected from the earliest Middle Miocene Moniwa Formation distributed in Sendai City, Northeast Honshu, Japan. This is the first record of the genus Aturia from Northeast Honshu and the most northern distribution of the Miocene Aturia in the Japanese Islands. It indicates a warm current inflow in the Sendai district during the early Middle Miocene time.
