Buyeo Sa

Buyeo Sa (扶餘泰, ? – ?) was a prince of Baekje, one of the Three Kingdoms of Korea. He was the son of Buyeo Pung by a Japanese woman and also grandson of the last king of Baekje, Uija of Baekje. He is also called Sa-wang (絲王). In Japan he was known as Teika-Ō (禎嘉王), also as Kudara no Ookimi and Kudara no Miko (百済王).
He had been in Japan when Sabi, the capital fell to the Silla–Tang alliance in 660 and his grandfather and uncles were taken to China. His father was crowned by Gwisil Boksin as King Pungjang (豊璋王) but they were defeated in 663 and his father was sent to China as well. After that Sa became the nominal successor to the throne of Baekje but this chance never came and Baekje was gone forever. The "Nihon Shoki" records that he was assassinated by Silla agents in Japan. He settled in Miyazaki Prefecture, Kyushu and as recorded in the "Shinsen Shōjiroku" became ancestor of Japanese clans. His immediate descendants were still called (百濟王, "King of Baekje").
One of his uncles, Zenkō (善光 or 禅広), also settled in Japan and was given the family name Kudara no Konikishi (百濟王; king of Baekje) by the emperor of Japan.
There is a shrine in Miyazuki Prefecture dedicated to him and his family, Mikado-jinja (神門神社), located in Misato Cho, Mikado village (美郷町南郷区神門). Buyeo Sa (Teika-Ō) is worshiped as the main deity.
He goes to visit his father at Mikado Jinja during a special festival parade once a year. The simple shrine is located in a lonely pine forest and tended to by the local people. It is supposed to be the former residence of Teika-O. Most of its history is still shrouded in mystery."
