I apologize if the question seems rather dumb (it's very rare that I venture in this part of the forums) but I'm curious as to how well integrated the territories were under the Japanese empire by the Second World War, particularly in the South Pacific. Would it be safe to assume that say if the Second World War (and I mean Japan confronting the likes of the United States, Britain, France, etc.) had somehow been avoided, would it had been safe to say that say the locals in the Japanese-administrated South Pacific Mandate would had been completely assimilated or overwhelmed by settlers from the Home Islands?
