Would it have been possible for a conquistador (Possible relative to Cortez like the one who conquered the Inca, or even the same one possibly) to have traveled to Hokkaido, allied with the Ainu and possibly some others on the mainland and then established a client shogunate after looting the daiymo of their wealth?
The Kanto plain should be easy enough to take with superior technology and armor and if there are any veterans from the Inca conquests then warfare in the Japanese mountains would seem like a piece of cake compared to the Andes.
But I was always fond of the Idea of the Ainu or some other Siberian people establishing a new Dynasty in Japan like the Mongols did in China.
