To be clear, the Japanese face 'extinction'. The lumps of rock called Japan will still exist and though they may no longer be called Japan in one thousand years. Does anyone really care about these things? Granted there is the tipping point where there aren't enough young to pay for/ look after the old (usually natural immigration can fix this). Other than that does it really matter? The useful genes that reside in the Japanese population will have made it out by then anyway. I seem to remember that the Europeans have ~500 years. As a European I don't feel threatened or moved by this.
