Other countries have this issue, but they offset it with strong immigration and foreign workers, to include a clear and easy path to citizenship or permanent residence. The problem with Japan (and a few other countries), is there are extremely high levels of racist and nationalistic ideology (even towards other Asians) over "purity", which aren't often openly discussed for trade and public relations. These kinds of attitudes often devolve into policies that aren't going to help the tax base. It also exacerbates the problem, as more "foreigners" discover they aren't really welcomed nor will be accepted. So, Japan will remain "pure", as its population steadily and rapidly decreases. It's arguably a Japan problem, if they want to dwindle into irrelevancy (and some are content to do exactly that), while entertaining and indulging in various prejudices and discrimination.
