As you might know, Toyotomi Hideyoshi attempted to invade Korea and China in the late sixteenth century, but was eventually repulsed after a protracted military campaign. I'm not asking whether it's possible if he could have won, but what he might have done if he did- what were his plans, or how would he organize his conquered lands? Would he have declared himself Emperor of China, and how would this gel with Japanese daimyo? Would such a claim be considered an insult to the Emperor of Japan- would he be a tributary to Hideyoshi or would the office of Emperor of Japan be abolished entirely as a threat to his authority? Additionally, where would he have moved his court, and how thoroughly would he be assimilated to Chinese-style governance?
