Japanese Unemployment Isn't Increasing-It's Population Is Aging
Unemployment is thus in fact lower than in a very long time. The reason why the ratio of workers to the total population has dropped is not that unemployment has increased -again, it has in fact dropped- but that Japan is rapidly becoming something of a nation of geezers.
Japan has, much like the other former leading World War II axis power, for decades had a very low birth rate something that together with Japan's "no gaijins allowed" immigration policy now results in a shrinking work force. Meanwhile, Japan's extremely high life expectancy means that the number of old people grows fast even as the number of young people shrinks fast.
