Is it possible for Taiwan to be an Island where in japanese, filipinos and chinese live together far as I know Orchid Island was settled by Filipinos before the Spanish came and the Japanese colonized it in OTL.
I was actually thinking of Taiwan being ruled by a Philippine State/Faction and later a Japanese faction before being in chinese control.If one of the empires — say, the British or the French — had taken it over and seriously developed it, they might have encouraged immigration from China, Japan and the Philippines.
There should be also a way to increase the 'Filipino' population on Taiwan..Migration between Taiwan and the Philippines went in both directions, but there was never really any contact between the people. The Tao on Orchid Island didn't even have a lot of contact with the tribes on mainland Taiwan. There were a few scattered Japanese and Chinese living on the island long before the Dutch came, you just have to find a way to increase their numbers. In my Taiwan timeline, there was a gold rush in northern Taiwan around the time Japan takes over Okinawa, so many Okinawans decide to go to Taiwan rather than live under the rule of the Satsuma clan. The problem is that the aboriginals had very low population densities. Any significant migration from China or Japan is probably going to overwhelm them.
