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.

Among the Gaya empires, Geumgwan-Gaya, Dae-Ggaya, Ara-Gaya, and Dara-Guk were found to have fortresses where kings and rulers lived. The archaeological aspects, including the surrounding ruins, were organized and the structural features and scenery of the Gaya Kingdom were explored in a macro-level manner. No roads or temples were built based on urban areas such as Silla and Baekje. However, it was confirmed that royal palaces, settlements, royal tombs, ritual facilities, and production facilities were all part of the ancient capital city system. And the view that the royal palace and the Wangmyo station are close to each other within a kilometer of distance can be seen as one of the common characteristics of Gaya's royal castle. Gaya established the space structure of the fortress while building the fortress, which is a memorial facility for the royal palace. In particular, the pattern of placing important facilities in the center and moving special production facilities to the outskirts can be seen as evidence of the perception of the capital city system. However, in the case of Geumgwan Gaya, it must have been difficult to develop into a capital city system due to the 400 years of the southern conquest of Goguryeo and the westward advance of Silla after the establishment of an earthen rampart. It is understood that Dae-Gaya and Ara-Gaya, which were great kingdoms of the end of the Gaya period, were also not in a condition to concentrate on the development of the capital from the establishment of an earthen rampart to the late 5th century. In other words, Gaya is an unfinished city, and in other words, the best archaeological data showing the transition period of the ancient Korean peninsula's capital system is Gaya's royal castle.

The three ancient tombs in the So-gaya are the Jungchon-ri ancient tombs in Sancheong, Samga ancient tombs in Hapcheon, and Songhak- dong ancient tombs in Goseong. Jungchon ancient tombs were influenced by the construction technique of Dae-gaya ancient tombs and relics such as the long sword with ring pommel. Ancient tomb construction techniques include soil-building techniques, circular burial stone marker, and soil-building materials. Later, the construction techniques of Samga ancient tombs and Goa-dong stone chamber were also influenced. It served as a link between Dae-gaya and So-gaya. Samga ancient tombs is a multi-bracket system that extends the land horizontally and vertically. It is possible to have affected the lower tombs in Dae-gaya ancient tombs. The construction techniques of Ara-gaya ancient tombs, such as compartmental soil-building techniques and wooden structures, were influenced. Songhak-dong ancient tombs are the most strongly married places, including the structure of tombs, tomb layout, ditch enclosure, junction, twin tombs and horse harnesses. And clayblocks was used a lot in the construction of the clay.
