Japan is very short on young people; how easily can it afford to waste a decade of their career? Productivity growth. Which literally means "every year, fewer people are able to produce more stuff". There's also the problem of the global economic slump. Which literally means "we have lots of things that could be done, like fixing hundred-year-old pipes and buildings. And we have lots of extra workers who could be doing things. But they are compelled to sit around twiddling their thumbs in their Japanese corporate cubicles, or their American parents' basements, or whatever, watching stuff crumble, because the economic equilibrium is stuck in low gear".
