29.8% of Japan’s population is over 65 years old, nearly three times the global average of 10.4%. With a median age of 49.9 years, the highest in the world after Monaco, the country is transforming into a global laboratory for aging. But this demographic crisis is gradually becoming an economic asset: automation and robotics, partly promoted by the government, constitute Japan’s natural response to an aging workforce.
This anticipated transformation of aging challenges could create a competitive advantage that is exportable to other developed, aging countries. AI and robotics technologies for care are presented as a solution to care shortages not only in Japan but also in other industrialized countries with rapid aging such as South Korea and the United Kingdom, with Japan actively exploring market opportunities in China and India.
Labor Shortages Force Massive Automation
In 2024, approximately half of Japanese companies surveyed indicate a lack of qualified full-time employees to meet their operational needs. Construction, ICT, and medical services are the sectors facing the most severe labor shortages. With an aging population of 123.3 million and low birth rates, the world’s fourth-largest economy could face a shortage of 11 million workers by 2040.
These shortages affect all economic sectors. Labor shortages have forced Japanese retailers and convenience stores to reduce their hours and services. In 2020, Japanese convenience stores lacked 172,000 workers, and the industry body predicts a deficit of 101,000 workers by 2025. As a result, only 87% of convenience stores are now open 24 hours a day, compared to 92% in August 2019.
The healthcare sector illustrates the scale of the challenge. By 2040, the country will face a shortage of 570,000 care workers, even though 33% of the population is already over 65. The nursing sector currently has only one candidate for 4.25 available jobs. The Ministry of Health anticipates a shortage of approximately 380,000 care workers by 2025.
Automation Extends Beyond Traditional Industry
Sectoral data on the stock of software per capita from 2002 to 2022 show that Japan’s software investments are negatively correlated with the share of workers aged 34 and under, suggesting that an aging population may have accelerated automation. In 2022, Japan had one of the highest densities of robots in the manufacturing industry.
Automation is now extending to unexpected sectors. For decades, the major Japanese confectionery company Lotte had delivered its famous chocolate-shaped biscuits, Koala’s March, by truck. However, due to an acute shortage of truck drivers caused by new rules on overtime hours, Lotte will now deliver this beloved children’s snack by train. Other companies across Japan, including automaker Toyota and e-commerce company Rakuten, are also preparing to deal with the driver shortage.
In logistics, Mujin, a Tokyo-based robotics company, has deployed its AI-powered robotic arms on more than 100 warehouse sites for customers including major retailers and third-party logistics providers, automating palletizing and depalletizing tasks that facilities can no longer staff. The company reports that its systems handle throughput comparable to three or four human workers per station.
In construction, a sector where Japan’s labor shortage is particularly severe and the average age of workers now exceeds 50 years, Shimizu Corporation and Obayashi have deployed autonomous welding robots, concrete finishing machines, and AI-guided cranes on active job sites. Shimizu’s Robo-Welder system demonstrated a reduction of approximately 70% in human welding hours required on structural steel projects.
Japan Dominates Global Robotics Exports
Japan is the world’s leading manufacturer of industrial robots, supplying 45% of global supply. In recent years, the country’s robot suppliers have significantly increased production capacity: their export ratio reached 78% in 2020, with 136,069 industrial robots shipped. Japanese industrial robot exports have had an average compound annual growth rate of 6% over the past five years. 36% of Japanese robotics and automation technology exports were destined for China.
This dominance extends to service technologies. According to Renub Research, Japan’s service robotics market is expected to reach $16.7 billion USD by 2033, up from $1.3 billion USD in 2024, with a remarkable CAGR of 32.66% from 2025 to 2033. By 2033, with a market expected to exceed $16.6 billion USD, Japan is not just adopting robotics — it is defining the global future of human-robot collaboration. The country’s experience is likely to become a model for technologically advanced and aging societies worldwide.
Government investment supports this export ambition. Japan’s Ministry of Economy, Trade and Industry stated in March 2026 that it aimed to build a domestic physical AI sector and capture 30% of the global market by 2040. The country already holds a strong position in industrial robotics, with Japanese manufacturers representing approximately 70% of the global market in 2022.
Aging Markets Converge Toward Japanese Solutions
This expertise finds immediate outlets in countries facing the same demographic challenges. South Korea’s fertility rate, now the lowest in the world at 0.72, means it will reach Japan’s level of labor force contraction within the next decade. Germany’s working-age population is expected to decline by approximately 7 million by 2035, and its manufacturing sector is already reporting a record number of unfilled positions.
Even China, despite its current dominance in manufacturing labor, faces a demographic cliff: its working-age population peaked in 2015 and is now declining at an accelerating rate. More than one-third of the world’s elderly (65 and older) live in East Asia and the Pacific, and many of the economic concerns first raised in Japan can be projected across the rest of the region. India’s population is aging in a similar manner to Japan’s, but with a 50-year lag.
The private sector is leading technological deployments in industrial sectors hard hit by Japan’s aging population, ranging from construction and transport to medical care and finance, with strong government support in each of these areas. In many cases, the underlying technologies related to AI, software, and robotics are already available in some form, but have not been developed and commercialized to the point of widespread deployment.
Cultural Acceptance Facilitates Adoption
Unlike many countries where social robots face skepticism, the Japanese population is highly receptive to robotic assistants. This cultural openness facilitates the development of solutions that other countries struggle to deploy. Japan’s regulatory willingness to authorize autonomous systems in mixed environments such as construction sites, farms, and retail stores proves as important as the technology itself, and countries that wait until the labor crisis becomes acute before updating regulatory frameworks will find themselves a decade behind on deployment infrastructure.
In some Japanese hotels, AI-equipped robots are deployed at receptions due to difficulties in securing front desk staff. In the security industry, AI-piloted security robots are used in response to security personnel shortages. In the food delivery sector, AI-powered delivery robots are increasingly used to compensate for the lack of available couriers. Similarly, in the restaurant sector, AI-equipped robots are actively providing meal delivery services to customers in place of human staff.
The path to exporting these innovations is accelerating. By deploying technologies to address societal challenges that result from its extreme demographics, Japan is positioned to be a leader in global markets. In 2022, its revenues from global markets were more than three times its domestic revenues, with 2.08 trillion yen in overseas operations in 120 countries, and 602 billion yen in Japan. This demographic transformation, long perceived as a weakness, is becoming Japan’s comparative advantage in the global automation economy.
