, was the third son of King Muryeong of Baekje. Some scholars believe he may be the same person as Prince Junda.[1] [2]
In October, 504, king Muryeong of Baekje sent a diplomat named Managun with tribute to Emperor Buretsu of Japan. Buretsu was angry that Baekje had not sent an envoy in a long time and detained the envoy. So, in April, 505 Muryeong sent a new envoy with Maagun with tribute but this time sending a message to Buretsu: “Previously to submit tribute I dispatched Managun, who was of no relation to the royalty of Baekje. Therefore, I humbly send Saa, that he may serve in the court.” He eventually had a son, the monk named Kun. He was the ancestor of the Yamato no Kimi.[3]
