Japan has a way to go, but gradually they're thinking more about immigration as a necessity, which was pretty much never an issue before. In those Japanese newspapers I read there are more and more articles about how local governments and also the national government are (economically) supporting companies giving language training to immigrant workers, with the idea that they want them to stay. Similarly, some cities are setting up programs which try to get foreign students to stay after graduation. There's still much which has to change (see comments by others). But it's still a bit behind and the population will almost certainly continue to decline for some years, as it has for a decade now.
