Japan ought to be our canary in a coalmine...it may have been different reasons but essentially being in a relationship is viewed as too costly to most people there and subsequently they are the only people breeding less than whites. They finally fell victim to the UN immigration shit and the 30 muzzies there now will likely outbreed them in 18 years (it is so much easier to up your birthrates when you start fucking them early and wait for the puberty to catch up)
