Gloomy Stories About the Future Are Making Young Japanese Skip Marriage and Children

Japan has spent decades trying to reverse one of the steepest fertility declines in the world, pouring money into childcare allowances, parental leave schemes and matchmaking programs, yet the birth rate keeps sliding. A new study published in the journal Genus offers a provocative explanation for why family policies alone have not worked: what discourages young Japanese from marrying and having children may not only be their current circumstances, but the stories they tell themselves about the future. According to the research, pessimistic narratives about the economy and about the country’s shrinking population measurably dampen both marriage intentions and fertility intentions among unmarried young adults.

The study, conducted by Shigeki Matsuda of the School of Contemporary Sociology at Chukyo University, applies a narrative framework to a question that has long puzzled demographers. East Asian countries including Japan have experienced persistent economic change and have expanded family policies, yet fertility rates remain stubbornly low. Matsuda’s hypothesis was that widespread pessimism about future economic and demographic conditions acts as a brake on family formation, operating independently of people’s actual present-day resources.

To test this idea, the researcher turned to a factorial survey experiment, a method that allows investigators to isolate the causal effect of specific scenario elements on people’s stated intentions. The survey targeted unmarried individuals aged 23 to 32 years in Japan, a group at the prime age for family formation decisions. A total of 2,270 respondents participated, providing a substantial sample in a national context where low levels of cohabitation and nonmarital childbearing, combined with declining marriage rates, are the main engines of fertility decline. In Japan, unlike in many Western countries, the path to parenthood overwhelmingly runs through marriage, so intentions to marry and intentions to have children are tightly linked.

The experimental design was elegant in its simplicity. Each respondent evaluated vignettes describing possible futures for Japan, constructed across three dimensions: the economy, the population, and policy. For each dimension, the scenarios came in three flavors: positive, status quo, and negative. An economic scenario might describe robust growth or prolonged stagnation; a population scenario might portray a stabilizing society or one gripped by rapid aging and decline; a policy scenario might depict significant expansion of family support or continued modest provision. These elements were randomly combined, so each participant saw a unique mix of futures, and the randomization ensures that any differences in reported intentions can be attributed to the scenarios themselves rather than to pre-existing differences between respondents.

The results were striking in their pattern. Economic scenarios clearly affected both marriage and fertility intentions: when respondents read about a brightening economy, their willingness to marry and have children rose, and when they read about economic deterioration, those intentions fell. This aligns with long-standing findings that economic insecurity pushes family formation later or out of reach entirely, but the experimental design here demonstrates the effect directly rather than inferring it from observational correlations.

Perhaps more surprising was the power of population narratives. Negative population scenarios, in which respondents confronted visions of a society shrinking and aging, reduced both marriage and fertility intentions. This finding suggests a feedback loop with unsettling implications: if pervasive public discourse about demographic decline makes young people less inclined to start families, then the resulting behavior could accelerate the very decline being described. Demographers have long worried about the mechanics of low-fertility traps, and this study provides some of the first experimental evidence that the narrative environment itself may be one of the gears in that trap.

Policy scenarios also influenced both intentions, though the study’s framing of the overall findings is sobering. The author concludes that the spread of pessimistic narratives about the future of the economy and the population, coupled with a lack of significant policy expansion, may contribute to discouraging people from forming families. In other words, it is not merely that policies are inadequate in isolation; it is that inadequate policy expansion combined with a bleak narrative climate sends a coherent, discouraging signal about what kind of future awaits those who marry and have children in Japan today.

The theoretical contribution of the study extends beyond Japan. Narrative approaches have gained traction in the social sciences as researchers recognize that human decision-making is shaped not just by resources and constraints but by the interpretive frames through which people understand their lives. Matsuda’s work demonstrates that the narrative framework applies to both fertility and marriage intentions, and extends its relevance to East Asian contexts, where family formation follows distinctive patterns. In societies where nonmarital childbearing remains rare, understanding what shapes marriage intentions is effectively understanding what shapes fertility, making the narrative lens doubly important for the region.

The methodological rigor of the factorial survey design deserves emphasis. Because respondents were randomly assigned to vignette combinations, the study avoids the selection biases that plague survey research on family intentions, where optimistic people may both hold sunnier views of the future and be more inclined toward marriage regardless. Here, the same person could be made more or less willing to marry simply by changing the future they were asked to imagine, which is about as close to a causal demonstration as survey research can offer. The survey was conducted with the approval of the Ethics Review Board for Human Subjects Research at Chukyo University, and the work was supported by a research grant from Chukyo University and the Japan Society for the Promotion of Science through KAKENHI grants.

For policymakers, the study points toward directions that go beyond the standard toolkit. If narratives matter, then how governments and media communicate about the demographic future is itself a policy variable. Endless headlines about population collapse may be counterproductive if they entrench the pessimism that the research shows suppresses family intentions. At the same time, the finding that policy scenarios influence intentions suggests that visible, significant expansion of family support could do double duty, improving material conditions while also shifting the story young adults tell about whether the future is a place where families can thrive. As Japan and its East Asian neighbors confront the demographic challenges of the coming decades, the study suggests that winning the battle of narratives may be as important as winning the battle of budgets.
