The Gongji was sent to Waeguk for a long time in the late 5th century. This was a measure of King Gaero to restrain Konji's forces in Baekje and to inherit the throne to his children. After settling in the Kawachi-Asuka area, Konji protected and united the Baekje immigrants and built an economic foundation. It is believed that Konji formed descendants while staying in Waeguk, and formed a support base both domestically and internationally by establishing relationships with the forces in Baekje. Based on this foundation, his son, King Dongseong, was able to take office despite internal and external chaos in the early days of Woongjin.
In Waeguk a descendant clan named Asukabenomiyatuko-si succeeds Konji. Asukabenomiyatuko-si grows up by forming a close relationship with the Yamato Kingship based on the Asukabe-gun Kawachi-guk. Later, in the Nara and Hyeian era, many bureaucrats of statute were produced, and their descendants continue to emphasize that they are the descendants of Baekje Gonji. These descendants of Gonji played an important role in forming a culture rich in Baekje color in ancient Japan.
