Japan is moving towards the 'kite' formation common to aging populations which throughout history resembled more of a pyramid, and more often today look like a cylinder. The simple solution would be immigration which will occur eventually whether or not the politicians and people of Japan want it. It would be better to do it now and slower then later on and with larger groups because acclimating foreigners to Japanese society will be more difficult if large enough populations of immigrants can come in to form their own communities. Perhaps that would be best, who knows, but the Japanese would probably prefer more aggressively allowing Koreans and Chinese in small amounts today then large waves in 30 years when they desperately need the additional labor, or allow their country to become internationally irrelevant.
