Japan's relative poverty rate as of 2007 stood at 15.7 percent, the Health, Labor and Welfare Ministry announced last October. This marks the first time the government has officially released its own data on the subject. Past rates were known only through surveys conducted by the Organization for Economic Cooperation and Development. The public announcement of this data is a welcome end to the willful denial of previous administrations, but one demanding a response and action.

The 2007 relative poverty rate, up from 14.9 percent in the 2004 OECD survey, is the fourth-highest among OECD's 30 member nations. With half the median income for all income earners in the nation serving as the dividing line, the relative poverty rate is likely to have worsened in the past few years, but we will never know until more recent data is forthcoming. For now, though, the reality is that 19 million Japanese are living below the poverty line, or nearly one in every six citizens.

Japan may imagine itself as middle class and, compared with other OECD countries, the distribution of income before redistribution has remained better than many, but Japanese society is increasingly becoming pear-shaped. The elderly, older workers, recent unemployed graduates and especially single mothers and their children make up an ever-larger portion of those in poverty. According to the OECD survey, some 59 percent of those below the poverty line are single parents. This figure was one of the worst of all OECD countries in 2004.
