Emperor Yōmei (用明天皇 Yōmei Tennnō) (died 587) was the 31st imperial ruler of Japan, according to the traditional order of succession.
Emperor Yōmei was the fourth prince of Emperor Kimmei and his mother was Soga no Kitashihime, a daughter of Soga no Iname.
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.
Emperor Sushun (崇峻天皇 Sushun Tennō) was the 32nd imperial ruler of Japan (587-592), according to the traditional order of succession.
He was the twelfth son of the Emperor Kimmei by Oane no Kimi, a daughter of Soga no Iname who was the chief of the Soga clan.
He succeeded his half brother, Emperor Yōmei in 587 with the support of the Soga clan and Empress Suiko, his half sister and the widow of Emperor Bidatsu.
