Keitai (継体天皇 Keitai-tennō), also known as Keitai okimi, was the 26th Japanese imperial ruler, accoring to the traditional order of succession. No firm dates can be assigned to this emperor's life or reign. Keitai is considered to have ruled the country during the early-6th century, but there is a paucity of information about him. Scholars can only lament that, at this time, there is insufficient material available for further verification and study.
