TOKYO -- Longevity is a blessing, but the Japanese live inconveniently long lives. Inconvenient, that is, for those who administer Japan's welfare state.
Welfare states are made possible by the productivity of modern economies, which make possible living conditions -- improved nutrition, hygiene, housing, medical care, education, environment -- that increase life expectancy. That increase threatens the solvency of welfare states, because the elderly receive most government transfer payments -- pensions and medical care.
The life expectancy of Japanese women (85.5) is the world's highest and that of men (78.5) is behind only Hong Kong and Switzerland. The median age here is 41.2, compared to 36.5 in America, and is projected to be 49.5 in 2050, when 37 percent of the population -- twice today's rate -- will be more than 65. And 41.7 percent will be more than 60, compared with 26.4 percent in America.
Japan, which has closed 4,000 schools in the last 20 years, has a fertility rate -- the number of children per woman of childbearing age -- of 1.32. The replacement rate, which keeps population from shrinking, is 2.1. Last year, deaths exceeded births by 21,408. The U.S. fertility rate is barely at replacement level, but immigration is one reason why demographer Nicholas Eberstadt expects America to be the ``only industrialized country to hold its share of global population in the next half century.''
Japan has never been welcoming toward immigrants. Shinzo Abe, who almost certainly will become prime minister this month, says he wants a Japan where ``people in other parts of the world would like to live'' and ``become citizens.'' But other senior officials say the way to square a declining population and work force with the pension costs of long-lived retirees is to rethink retirement -- to ``work for life,'' one official says.
Another says of immigration that it is wrong to import workers to do ``hard, risky jobs. Hardships should be shouldered by the Japanese themselves.'' And, he asks, ``Why should we increase our population?'' Leaving aside the welfare state's grinding imperatives, that is not a foolish question. In 1920, Japan's population was 56 million. Today it is 127.5 million on a landmass the size of California (population 36 million) that is three-quarters mountainous. A third official, noting that Japan imports 60 percent of its staple foods, says, ``It might be good to have a declining population'' of, say, 100 million by 2050.
