It's theorized that Emperor Yūryaku may be synonymous with [[Bu of Wa|King Bu]] (武) as written in the Chinese records. According to the [[Book of Song]], Bu dispatched envoys to [[Emperor Shun of Song]] ([[Liu Song dynasty|a Southern Chinese dynasty]]) in both 477 and 478 AD. The first envoy was to inform the Chinese emperor that [[Kō of Wa|King Kō]] ([[Emperor Ankō]]) had died, and his older brother had become king.<ref>{{cite book|url=https://books.google.com/books?id=vaSzIi_HQlsC|title=Gateway to Japan: Hakata in War and Peace, 500-1300|author=Bruce L.

The full context of this latter passage describes how Bu's ancestors conquered countries, and expanded their power to the east and west. It describes how they crossed [[Korea Strait|the sea]] to the north and reached the southern part of the [[Korean Peninsula]]. Although the kings of Wa repeatedly requested that the Emperors of the Song dynasty recognize their military control over [[Baekje]], their efforts were denied. The reason for this is thought to be that the Song dynasty placed importance on Baekje, which was located in a strategically important area. By not offering recognition the Song Emperors could put the [[Northern Wei]] in check, and avoid opposition from [[Goguryeo]] which was in conflict with Wa.<ref>{{cite book|title=Emperor Yuryaku and His Era|author=Arikiyo Saeki|publisher=Yoshikawa Kobunkan|year=1988|pages=26–27|isbn=978-4-642-02145-6}}</ref> Scholar [[Francis Brinkley]] notes that the power of the [[Koma clan]] (supported by the Liu Song dynasty) in Goguryeo increased steadily during this time. Brinkley suggests that Emperor Yūryaku's attempts to establish close relations with the Chinese Emperor seem to be from a desire to isolate Korea, which ended in failure.<ref name="Brinkley"/>

The other two recorded instances regarding King Bu are mentioned in the books of [[Book of Qi|Qi]], and [[Book of Liang|Liang]]. As compared to the former mention in 478 AD, these are not considered to be reliable.<ref name="Kawachi">{{cite book|title=The Five Kings of Wa: Throne Succession and East Asia in the Fifth Century|author=Haruto Kawachi|publisher=Chuoko Shinsho|year=2018|page=207-228|isbn=978-4-121-02470-1}}</ref> Japanese historian Mori Kimiaki points out that both of these appointments coincide with the founding year of their respective dynasties. This is thought to be an administrative matter, and it is not clear whether King Bu (Yūryaku) himself requested it or not.<ref>{{cite book|title=The Five Kings of Wa: 5th Century East Asia and the Statue of the Wa Kings|author=Mori Kimiaki|publisher=Yamakawa Publishing Co., Ltd.|year=2010|page=7-11|isbn=978-4-634-54802-2}}</ref> There is at least 1 theory that supports the envoy being sent to [[Southern Qi]] in 479 as being factual. This is solely based though, on the description in the title of {{Nihongo|''Shoban Shokugu Illustrated Scrolls''|諸番職貢図巻}} included in {{Nihongo|''Ainichi Ginro Sho Ga Zuroku''|愛日吟盧書画続録}}.<ref name="Kawachi"/> The fourth and final appointment allegedly made by King Bu (Yūryaku) falls outside of his recorded lifetime. As the ''Kiki'' states that Emperor Yūryaku died in 479, the last given year of 502 AD would be implausible.
