Japan should keep Japan for the Japanese.
They should not do what the American left did, start replacing themselves with the populations of Somalia, and Kenya, and Mexico, and Latin America, and all the violent, peasant nations of the world. With immigration rates that have already put them in the minority, and which will make them disappear entirely from their nation’s identity and culture, and leadership within a few decades.
Why would any nation’s people, end themselves?
Japan is different, that is true. But America is a nation of immigrants and I don’t have a problem with immigration as long as it is done legally.
Our ancestors came from somewhere else, remember.
