Don't ever let anyone in, all immigrants ever do is destroy the native culture, and genetically replace you. There has never been a case where mass immigration didn't destroy the culture and people who accepted them, please don't make the mistakes the liberals have made in Europe and the US. Japanese culture and the Japanese race is so beautiful, don't ever let it be destroyed. This is a warning from the US, don't be stupid keep your doors locked tight.?They seem such nice people in Japan.
