Faced with this comeback by Koguryo, Paekche leaders turned to Yamato for military support, even sending its crown prince to Yamato as a hostage in 397 – just as Silla had dispatched princely hostage to Koguryo in 392 when that kingdom was in dire need of military support.
We can only guess, for example, what it felt like for the girls periodically sent as brides to foreign courts, for the crown prince of Paekche when he was dispatched to the Yamato court as a hostage in AD 397, or for a Silla prince who experienced the same fate in 402.
Paekche was frequently attacked by Koguryo during the century, prompting continued requests for assistance from Yamato; it is recorded that Paekche even sent a crown prince to Yamato as a hostage on one occasion and the mother of the king on another. Yet, probably because of internal dissension, Yamato did not dispatch any troops to the peninsula. Yamato's interest in Korea was apparently a desire for access to improved continental technology and resources, especially iron.
In 402, Silla concluded a peace with the Wa. Prince Misahun was then sent to Japan as a hostage. This may have been an act of revenge by the Silla monarch, who, as Prince Silsong, had been sent as hostage to Koguryo by Prince Misahun's father. Despite the peace, Silla–Wa relations were never friendly, due no doubt in part to the Wa–Kaya alliance.
