Japan, the world’s fourth-largest economy, today stands as a critical test case for the global future of work. Confronted with a rapidly ageing population and a shrinking labour force, the country has turned to artificial intelligence (AI) and robotics as instruments of economic resilience and social adaptation. Team Mirai, a political party in Japan, founded and led by AI engineer Takahiro Anno, emerged with 11 proportional representation seats during the February 2026 lower house elections. The party proposed using AI to replace workers, including foreign nationals, as a response to Japan’s ageing society and labour shortages — framing automation as a way to reform industries and reduce reliance on foreign labour.
This strategic pivot reflects a broader attempt to reconfigure the relationship among humans, work, and welfare in a society facing demographic challenges. Japan’s technological experience offers insights for policymakers worldwide while also raising questions regarding the limits of technological substitution. Japan faces a stark demographic reality, with around 30 percent of its population aged 65 or above, and has one of the lowest fertility rates in the world. This has caused a sharp decline in the working-age population, threatening economic growth and straining healthcare and pension systems. Against this backdrop, AI has emerged as a politically and economically feasible way to replenish lost labour capacity.
Robotics as a Demographic Response
Japan’s leadership in robotics has provided a concrete foundation for this transition. For instance, industrial giants such as Fanuc and innovators like SoftBank Robotics have integrated AI-led automation into manufacturing and services at scale. Automation serves as a solution to labour shortages, as there are too few workers to meet demand. Japan’s demographics are shaping its technological path in three key ways: a massive and growing market driven by an ageing population, severe labour shortages intensified by limited immigration and strict border policies, and supportive political and regulatory conditions that further encourage the adoption of new technologies. In sectors such as automotive production and electronics, robots have begun performing tasks with remarkable precision and efficiency, enabling firms to maintain output despite workforce shortages. The automation-led productivity model has enabled Japan to partially decouple its economic performance from demographic decline – an achievement that many ageing countries aspire to emulate.

Technology in the Caregiving Sector
However, the Japanese approach has extended beyond automation into the social domain, including elderly care. The ageing crisis is most prominent in the caregiving sector, where demand for services has increased. In this context, AI-enabled solutions — including robots, remote monitoring systems, and smart technologies — are being developed and deployed to bridge the gap between rising caregiving demand and a shrinking pool of caregivers. Tools such as Paro, a robotic companion, are designed to provide emotional comfort, illustrating how technology is also used to support psychological well-being among the elderly.
Japan’s AI strategy emphasises augmentation, in which AI is deployed to enhance human productivity and extend working lives. On 28 May 2025, Japan’s Parliament (Diet) approved the ‘Act on the Promotion of Research and Development and the Utilisation of AI-Related Technologies’ (AI Promotion Act) to promote research and utilisation of AI to foster socio-economic growth and enhance human productivity.
Furthermore, in the healthcare domain, AI-assisted diagnostics improve accuracy and reduce workloads for professionals. Under the framework of Society 5.0, the Japanese government has encouraged the deployment of AI-enabled healthcare systems, nursing-care robots, and workplace automation to support elderly citizens. These technologies are particularly designed to compensate for age-related physical and cognitive limitations and extend healthy lifespan.
In an ageing society like Japan, these approaches are essential to sustain economic activity and maintain the quality of life without relying on large-scale immigration and foreign workers. Japan’s approach shows a shift from viewing ageing as a demographic burden to treating technology as a means of enhancing human capabilities.
Limits of Technological Substitution
However, reliance on AI poses several challenges. Adopting advanced technologies comes with high costs that may create disparities between large corporations and small and medium-sized enterprises, aggravating economic inequality. Furthermore, while AI systems tend to replicate functional aspects of human labour, they still fall short in areas that require genuine empathy and complex social interaction. This limitation is especially prominent in caregiving, where emotional connection may underpin quality service. Japan also remains cautious about AI’s effects on employment, a wariness rooted in broader economic anxieties. People tend to weigh the risks of new technologies more heavily than their benefits when the future feels precarious — and many Japanese workers see generative AI and AI-powered robots as threats to jobs once done by humans.

While automation has been the primary response to labour shortages, there is a recognition that technology alone cannot compensate for the demographic decline. In recent years, Japan has been cautiously expanding its pathways for foreign workers through programmes such as the Specified Skilled Worker System, in sectors including healthcare, agriculture, and construction. However, Prime Minister Sanae Takaichi has adopted a selective and cautious immigration policy, emphasising cultural cohesion and domestic capacity-building. As a result, there is limited appetite for large-scale immigration as a solution to labour shortages. In this context, AI and selective immigration can function as complementary solutions. The long-term sustainability of Japan’s economic model will therefore depend on how effectively it can balance these approaches with efforts to maximise domestic labour participation.
Lessons for an Ageing World
Japan showcases how AI can serve as a powerful tool for sustaining productivity and supporting ageing societies. At the same time, it reveals the limits of a technology-centric approach, which cannot fully replace human empathy and trust.
Japan’s AI pivot is a necessary response to its demographic challenge, but it is not a complete one: technology can reshape economies under demographic strain, yet it cannot, on its own, resolve the human and economic pressures that come with an ageing society.
While AI offers opportunities to improve efficiency and augment human capabilities, concerns about job displacement and economic insecurity continue to shape public perceptions — a reminder that a society can adopt a technology out of necessity without fully embracing it.
The Japanese approach, however, points to how societies might design systems in which machines and humans complement rather than replace one another — AI absorbing the routine and physical tasks, humans remaining central where empathy and trust are required, as in caregiving. The success of this approach depends on balancing technological efficiency with the social costs of automation, from job-displacement anxiety to the risk of widening gaps between large firms and smaller ones.
