Four individuals of Matsudaira's Storm-petrel Oceanodroma matsudairae were observed in June 2010 in Sagami Bay, central Japan, where the syntype specimens were collected in May 1921. There has been no record of this species in this area since that time. This observation record may provide an important clue to reveal the migration route and fundamental ecology of this species.
