Tokyo’s Baby Boomlet: A Glimmer of Hope in a Demographically Dismal Japan

Tokyo’s recent surge in births, driven by increased marriages and supportive policies, has been hailed as a triumph for Governor Yuriko Koike’s “children first” agenda. However, what does this uptick really mean for Japan’s fertility crisis? Can Tokyo’s success be replicated elsewhere in the country?

Koike’s approach to addressing Tokyo’s demographic woes is rooted in her conviction that government must take an active role in supporting family formation. To that end, she has implemented a range of policies, including AI matchmaking through the Tokyo Enmusubi app and generous childcare subsidies. The results are promising: Tokyo registered 85,064 births in 2025, the first such increase in 10 years.

This uptick reflects a deeper shift in Japan’s societal attitudes towards family and work. Cultural reforms promoting paternity leave and women’s career advancement have helped reduce stigma around having children, creating a more supportive ecosystem for families to thrive. One of the key innovations behind Tokyo’s success is its AI matchmaking app, which has registered over 38,000 users and facilitated at least 300 marriages.

Tokyo stands out from other Japanese prefectures due to its willingness to experiment with unconventional policies. By bypassing national bureaucracy, Koike has created a living laboratory for families, where innovative approaches can be tested and refined. This approach has also earned the city international attention, with policymakers in Singapore taking note of Tokyo’s pioneering work.

However, Tokyo’s baby boomlet is not without its challenges. The city’s fertility rate remains one of the lowest in Japan, at 0.96. Moreover, the uptick in births is largely driven by young couples migrating to the capital for work, rather than a genuine increase in fertility rates. To sustain this momentum, Tokyo will need to continue innovating and adapting its policies to meet the changing needs of its residents.

As Japan grapples with its own demographic challenges, Tokyo’s experience offers a glimmer of hope. By prioritizing family formation and providing support for couples at every stage of their lives, Koike has shown that even in a country notorious for its low fertility rates, change is possible.

Tokyo’s success may also offer lessons for other cities facing similar urban and demographic challenges. Cities like Singapore and Seoul, which are densely populated and ageing, may learn from Tokyo’s approach by prioritizing family formation and providing support for couples at every stage of their lives. By doing so, these cities can create a more supportive ecosystem for families to thrive.

Tokyo’s baby boomlet is not just a statistical anomaly; it represents a fundamental shift in Japan’s societal attitudes towards family and work. As Koike herself puts it, “Our role is to foster a sense of shared empathy and understanding across society so that everyone can feel secure enough to realise their own personal aspirations.” By embracing this vision, Tokyo has created a model for other cities to follow – a model that holds out the promise of a more family-friendly Japan.
