Justification of Red List category
The prevalence of threats from introduced predators on the species's main breeding grounds in Japan and additional factors such as fisheries bycatch and human disturbance suggests that the species is in overall decline. It is therefore precautionarily classified as Near Threatened as it almost meets the requirements for listing as threatened under criteria A2abe+3be+4abe. Further data are required from across its range to quantify the trend.
