After a long time searching threads, it seems to me that the general concensus amongst Alternate Historians is that after a successful invasion of Korea in the Imjin War, the Japanese shogunate would eventually fall apart.
My question is: How long would that take?
And more importantly, could Japan 'export' its Samurais and Daimyos, and maybe even its culture, by then? What about a Korean Shogun?
To top it all of, if this is possible, we might see a Korean Naval Empire, and even industrialisation in Korea (as mentioned in another thread somewhere) where bored peacetime Samurais either sponser or become merchants and inventors (IOTL Japan could of been the first industrialised nation in the world had it not been for its dogma against merchants and its isolationism).
For the purpose of the TL that I'm writing at the moment, lets assume the invasion of Korea is a success - and for those of you about to say its not possible, there's no Admiral Yi and China has been distracted by an invasion from the North.
