Who Is Emperor Keiko (Keiko Tenno)?

The twelfth emperor, father of Yamato Takeru

Otarashihiko-Oshirowake-no-Sumeramikoto

Emperor Keiko is the figure the Kojiki names as the twelfth emperor of Japan and the father of Yamato Takeru (Prince Ousu). He ruled from the Hishiro Palace at Makimuku.

When his elder son Ousu (Oousu) stopped coming to meals, the emperor told Prince Ousu to "instruct him kindly" — and Prince Ousu killed his brother. Fearing his son's violent nature, the emperor sent him west to destroy the Kumaso Takeru brothers. When the son returned, the emperor gave him no rest and immediately sent him to the eastern lands as well. Yamato Takeru lamented to his aunt, "Does my father wish me dead?"

The Kojiki records that Emperor Keiko had eighty children in all, counting those whose names were recorded and those whose names were not.
