Ask the native americans how they feel about being "replaced"? Maybe the cycle just repeats itself - if you live long enough to see it. I heard they used to speak French in England.
Yes, because there's nothing that says a country should be xenophobic, especially when Japanese themselves are not a single coherent race but a mixture from all over.

> The Yamato (大和民族, Yamato minzoku; lit. 'Yamato ethnicity') or Wajin (和人 / 倭人; lit. 'Wa people')[4] are an East Asian ethnic group that comprises over 98% of the population of Japan. Genetic and anthropometric studies have shown that the Yamato people predominantly descend from the Yayoi people, who migrated to Japan from the continent beginning during the 1st millennium BC, and to a lesser extent the indigenous Jōmon people who had inhabited the Japanese archipelago for millennia prior.[5]
> Generally, the Japanese are related to other East Asians like the Koreans and the Han Chinese, but can be genetically distinguished from them.[47][48] Japanese and Koreans diverged from each other about 1.4 KYA, around the Asuka period or the middle of the Three Kingdoms period.
