'he Japanese now have one of the lowest fertility rates in the world, and at the same time, one of the highest longevity rates. As a result, the population is dropping rapidly, and becoming increasingly weighted toward older people. After peaking seven years ago, at 128 million, Japan's population has been falling — and is on a path to decline by about a million people a year. By 2060, the government estimates, there will be just 87 million people in Japan; nearly half of them will be over 65. Without a dramatic change in either the birthrate or its restrictive immigration policies, Japan simply won't have enough workers to support its retirees, and will enter a demographic death spiral. Yet the babies aren't coming.

There are both cultural and economic barriers. In Japanese tradition, marriage was more about duty than romantic love. Arranged marriages were the norm well into the 1970s, and even into the 1990s most marriages were facilitated by "go-betweens," often the grooms' bosses. Left to their own devices, Japanese men aren't sure how to find wives — and many are shying away from the hunt, because they simply can't afford it. Wages have stagnated since the 1990s, while housing prices have shot up. A young Japanese man has good reason to believe that his standard of living would drop immensely if he had to house and support a wife and children — especially considering that his wife likely wouldn't be working.

In Japan, marriage usually ends a woman's working career, even though most women are well educated. Once they have a child, women face strong social pressure to quit their jobs and assume very traditional roles, serving both the husband and the child. Mothers who want to keep working are stigmatized and usually find that employers won't hire them. Child care is scarce and expensive, while Japan's brutal work culture often demands that employees work more than 50 hours a week. Japanese husbands aren't much help either — they spend an average of one hour a day helping with the children and household chores, compared with three hours for husbands in the U.S. and Western Europe. "You end up being a housewife with no independent income," bank worker Eri Tomita told The Observer. "It's not an option for women like me."

For years, Takeshi hid from the world, playing video games all night and sleeping all day, eating from a tray his mother left outside his room. He was a hikikomori, one of an estimated 1 million Japanese teens and young men who have become shut-ins, with virtually no human contact beyond their parents. Some of the hikikomori first withdraw because of some social embarrassment — bad grades, or a romantic rejection. The longer they drop out, the more shame they feel in a society where one's status and reputation are paramount and hard to change. Parents, and especially mothers, often enable the withdrawal. "In Japan, mothers and sons often have a symbiotic, codependent relationship," says psychiatrist Tamaki Saito, who first identified the disorder in the 1990s. Takeshi re-entered society after four years, thanks to a government program that sends female outreach counselors known as "rental sisters" to coax the hikikomori out of the house. But that program doesn't always work. As one shut-in of 15 years said, "I missed my chance."'
