The Tokyo metropolitan government has announced a bold initiative: the introduction of a four-day workweek for its employees from April 2025. This policy is aimed at improving work-life balance, particularly for working parents, and tackling some of the underlying societal issues contributing to Japan’s demographic challenges. This is also aimed at tackling its population crisis, marked by a declining birth rate and an aging population.
Supporting Work-Life Balance for Parents
The four-day workweek is designed to help employees, especially women, balance their professional and personal lives. Tokyo Governor Yuriko Koike emphasized the need for flexible work options to allow women to pursue careers while also managing childcare responsibilities. Alongside this, a new “childcare partial leave” policy has been implemented. It will allow some employees to work two fewer hours each day, giving parents additional time to care for their children.
Japan’s Fertility Crisis
Japan’s fertility rate stands at a critically low 1.2 children per woman, with Tokyo’s rate even lower at 0.99—far below the 2.1 rate needed to sustain the population. This trend has severe implications for the country’s economy, workforce, and social structures. Despite years of government initiatives, including parental leave policies, daycare subsidies, financial incentives for having children, and even a government-run dating app, the birth rate continues to decline.
The situation is further compounded by Japan’s aging population, which places additional strain on social services and creates an urgent need for innovative solutions to boost the birth rate and support younger families.
Four-Day Workweek: Potential Benefits
Adopting a four-day workweek could alleviate the pressures of Japan’s notoriously demanding work culture, which is often cited as a barrier to family life. Women, in particular, bear a disproportionate share of household and childcare responsibilities, making it difficult to balance these demands with full-time careers.
Research from trials in other countries has shown that a four-day workweek can encourage men to participate more in domestic responsibilities. For instance, men increased their childcare contributions by 22% during four-day workweek experiments globally, creating a more supportive environment for women and enabling them to consider larger families.
In addition to addressing work-life balance, studies indicate that four-day workweeks improve employee productivity, reduce stress, and enhance overall well-being. These outcomes align with the government’s goals of creating a healthier and more sustainable work environment.
Challenges and Expert Perspectives
While the four-day workweek holds promise, experts caution that it is not a standalone solution to Japan’s demographic issues. Addressing the declining birth rate and aging population will require a comprehensive strategy that includes societal changes, economic incentives, and workplace reforms.
The cultural stigma surrounding men’s participation in domestic duties and the deeply ingrained expectation of long working hours remain significant barriers to achieving gender equality at home and in the workplace. For the four-day workweek to succeed, broader societal attitudes toward work and family life must shift.
A Step Toward Broader Change
Despite these challenges, the Tokyo government’s initiative represents a step in the right direction. By setting an example with progressive workplace policies, the city hopes to inspire other organizations across Japan to adopt similar measures. Governor Koike expressed optimism that these changes would help create a more inclusive and supportive society where both men and women can thrive professionally and personally.
The four-day workweek and related policies are part of an evolving effort to address Japan’s demographic challenges. While they won’t solve the problem entirely, they could play a key role in creating an environment where young families feel supported, ultimately contributing to the nation’s long-term stability and prosperity.
