The nation's changing attitudes toward family also played a role in freeing up women for work. The average age of people marrying for the first time has been steadily rising, and fertility rates are at record lows. "Delaying marriage, delaying childbearing years, not getting married at all — that's the big societal backdrop," said Paul Sheard, an economist who has long been focused on the nation. But there have been limits. There is still a tax penalty for second earners in the country, and the quality of jobs women hold is not great. They are often lower paid and for limited hours. Women are also largely absent from leadership ranks in Japanese companies. Kathy Matsui, the former vice chair of Goldman Sachs Group's Japan unit and the woman who spearheaded womenomics as an idea, has said the effort needs continued work. Still, Japan's experience could explain what lies ahead in the United States. Fertility and marriage rates are also down in America, for instance, which could create space for working rates among young and middle-aged women to keep rising in the near term. However, it does plant the seeds for a smaller population and economy. Remote or hybrid work arrangements could also make working easier for caretakers. Experts have said that some of the more family-friendly policies that Japan has used could be a model for the United States.
