垂仁天皇
Some of the many Korean immigrants who settled in Japan beginning in the 4th century were the progenitors of Japanese clans. According to "Kojiki" and "Nihon Shoki", the oldest record of a Silla immigrant is Amenohiboko: a legendary prince of Silla who settled in Japan at the era of Emperor Suinin, possibly during the 3rd or 4th centuries.
