 According to Nihon Shoki, Emperor Yomei believed both in Buddhism and Shintoism.Moriya, the most influential supporter of Shintoism, conspired with Emperor Yōmei's brother, Prince Anahobe, and after Emperor Yomei's death they made an abortive attempt to seize the throne.Although Emperor Yōmei is reported to have died from illness, this incident and the brevity of his reign have led some to speculate that he was actually assassinated by Moriya and Prince Anahobe.
