Well, the country that attacked them wasn't so much defeated as corrupted into loving monsters, so there probably weren't any prisioners at all...

If they had another war, and if they made prisioners... I guess it would depend on who were to make the prisioners... Monsters would obviously rape the males and made them into husbands, while females would be monsterized. If there were an excess of male prisioners, they could release them after the war or export them to male-deprived Demon Realms...

If it were humans who took the prisioners... it depends on the influence monsters have on that Zipangunese human faction... If the monster hold great influence in that monsters, the prisioners would be handed to them... but otherwise.... well, the Ochimusha entry teaches us that Zipangunese kill each other in their wars, and they have samurais and bushido... so there is a chance they would treat their prisioners the way the samurais did: Behead them and send their heads to the daimyo for a reward...
