What POD could make the Japanese settle to Taiwan, is it a Mongol invasion of Japan or the fleeing Kirishitans could settle Taiwan and what would be the consequences of the Japanese settling Taiwan?
They did settle Taiwan... starting in 1895 (insert annoyingly self-righteous smily here)
OR the Ryukyu nation, later Kingdom (once an independant nation) settle it... Blessing of the chinese emperor maybe. Maybe they need more arms..
That is quite possible but Japan needs to annex Ryukyu in order for it to be completely annexed to Japan or else it will just be another Japonic polity.There was a suggestion once posted that 1185 might be a starting point of this development https://www.alternatehistory.com/discussi...d.php?t=168506
