Other historians, such as those who collaborated on 'Paekche of Korea and the Origin of Yamato Japan' and Jonathan W. Best, who helped translate what was left of the Baekje annals, have noted that these princes set up schools in Yamato Japan and took control of the Japanese naval forces during the war with Goguryeo, taking this as evidence of them being more along the lines of diplomats with some kind of familial tie to the Japanese imperial family and as evidence against any hostage status.
Andre historikere, såsom dem, der har samarbejdet om Paekche of Korea and the Origin of Yamato Japan og Jonathan W. Best, der hjalp med at oversætte, hvad der var tilbage af de Baekjes annaler, har bemærket, at disse prinser oprettede skoler i Yamato Japan og overtog kontrollen med de japanske flådestyrker under krigen med Goguryeo, og tager dette som bevis for at de snarere var diplomater med en form for familiær forbindelse med den japanske kejserlige familie og som bevis mod nogen form for gidselstatus.
