Japan’s demographic shift toward an older society is reshaping its economic landscape, driving expansion in healthcare, eldercare, and lifestyle sectors tailored to seniors. As of 2024, the nation counted 36.25 million individuals aged 65 or older—representing 29.3% of the total population—a figure expected to climb to 34.8% by 2040 and reach 36.3% by 2045. This aging trend positions Japan as the world’s most aged country, far surpassing other regions like Martinique, which ranks second with 25.3% of its residents in the same age group.
The economic impact of this shift is substantial. The so-called longevity economy in Japan is projected to grow from JPY 96 trillion ($652.5 billion) in 2023 to JPY 115 trillion ($780 billion) by 2040. Within this market, healthcare accounted for JPY 29 trillion ($195 billion), nursing services for JPY 11.7 trillion ($79 billion), and lifestyle-related industries for JPY 55.7 trillion ($378 billion) in 2023, illustrating a broad ecosystem supporting older adults’ daily needs.
Notably, the health and socioeconomic profile of Japan’s elderly has improved over the past 15 years, with data suggesting they are effectively “five years younger” in terms of physical well-being and workforce participation. Projections indicate a rise in elderly individuals with higher disposable income, especially those without spouses or children, further stimulating demand across multiple service sectors.
Technology is playing a pivotal role in meeting these evolving needs. In June 2024, Japan’s Ministry of Health, Labour and Welfare updated its policy framework to broaden support for technological applications in long-term care, now covering functional exercise assistance, nutritional support, and dementia care. For 2025, nearly JPY 30 billion ($203.5 million) in government subsidies have been allocated to accelerate adoption. Among emerging innovations are care robots such as AIREC, a humanoid developed by Waseda University and showcased at Expo 2025 Osaka, Kansai. Equipped with artificial intelligence, it can assist with tasks like putting on socks. Roadmaps anticipate commercialization of robots capable of household chores and low-risk caregiving by 2030, expanding into medical support and companionship roles by 2050.
Another growing sector is conversation partner services, responding to the rising number of seniors living alone—over 9 million in 2024, with 61.7% aged 75 or above. Social isolation increases risks for undetected illness and cognitive decline, prompting demand for human and AI-mediated interaction services. The market for such companionship is expected to exceed JPY 100 billion ($670 million). Platforms like Hahalol, targeting users aged 50 and older, use AI to match individuals for platonic or romantic relationships and have attracted JPY 560 million ($3.8 million) in investment.
These developments reflect broader global implications. As populations age worldwide, Japan’s experience offers insights into building resilient systems that combine innovation, social connection, and financial sustainability. Initiatives led by organizations such as the World Economic Forum emphasize health maintenance and social engagement as foundational to thriving longevity economies.

According to Japan’s Ministry of Internal Affairs and Communications, as of 2024, the country had a record 36.25 million people aged 65 and over, accounting for 29.3% of the total population. This share is projected to rise to 34.8% in 2040 and 36.3% in 2045. Japan’s proportion of elderly residents is already far higher than second-ranked Martinique (25.3%), making it the world’s most aged society. n nThe longevity economy in Japan is emerging as a market of considerable scale. It is expected to expand from JPY 96 trillion ($652.5 billion) in 2023 to JPY 115 trillion ($780 billion) by 2040. By sector, the elderly market in 2023 included JPY 29 trillion ($195 billion) in healthcare, JPY 11.7 trillion ($79 billion) in nursing care and JPY 55.7 trillion ($378 billion) in lifestyle-related industries, highlighting the diverse ecosystem supporting seniors’ daily lives. n nAnalyses show that Japan’s elderly population has become “five years younger” in terms of health status and employment rates over the past 15 years. Looking ahead, the number of seniors with higher disposable incomes, particularly those unmarried or without children, is projected to increase by 2040. These shifts are fuelling demand not only in healthcare and nursing care, but also in lifestyle-related industries, driving further market growth. n nDiscover n nWhat is the World Economic Forum doing to combat Alzheimer’s? n nAlzheimer’s Diesease, a result of rapid ageing that causes dementia, is a growing concern. Dementia, the seventh leading cause of death worldwide, cost the world $1.25 trillion in 2018, and affected about 50 million people in 2019. Without major breakthroughs, the number of people affected will triple by 2050, to 152 million. n nTo catalyse the fight against Alzheimer’s, the World Economic Forum is partnering with the Global CEO Initiative (CEOi) to form a coalition of public and private stakeholders – including pharmaceutical manufacturers, biotech companies, governments, international organizations, foundations and research agencies. n nLoading… n nThe initiative aims to advance pre-clinical research to advance the understanding of the disease, attract more capital by lowering the risks to investment in biomarkers, develop standing clinical trial platforms, and advance healthcare system readiness in the fields of detection, diagnosis, infrastructure and access. n nThe role of technology n nIn June 2024, the Ministry of Health, Labour and Welfare revised its “Priority Fields in the Use of Robot Technology for Long-term Care,” renaming it “Priority Fields in the Use of Technologies for Long-term Care.” The updated framework added three new focus areas: functional exercise support, assistance for eating and nutrition management, and daily support and long-term care support for people with dementia. To accelerate adoption, the government allocated nearly JPY 30 billion ($203.5 million) in subsidies in the 2025 budget. n nOne notable example of the use of technology is “care robots”. At Expo 2025 Osaka, Kansai, the humanoid robot AIREC, developed by Waseda University and others, was showcased. Equipped with AI, it can autonomously assist with daily tasks considered challenging such as putting on socks. The roadmap envisions commercialization of robots capable of household tasks and low-risk caregiving duties by 2030, expanding to hospitality, household chores, caregiving, nursing and some medical procedures by 2040. By 2050, these robots are expected to evolve into “companions” for the elderly, capable of communication through both language and touch. n nA growing market for conversation partner services n nBeyond healthcare and nursing care, lifestyle-related industries for seniors are rapidly expanding. One of the fast-growing segments is “conversation partner services.” According to the Ministry of Health, the number of single-person households aged 65 and older surpassed 9 million for the first time in 2024. Among these, 61.7% were comprised of individuals aged 75 and above. Seniors living alone face heightened risks, including delayed detection of illness and increased dementia risk due to reduced social interaction. Reflecting these challenges, the conversation partner service market is projected to exceed JPY 100 billion ($670 million). n nThese services range from casual daily companions to trained senior communicators. Regular interaction not only provides reassurance but also helps monitor seniors’ well-being. New AI-driven senior-focused matching platforms are also emerging. One example is Hahalol, a service for users aged 50 and above. Leveraging artificial intelligence (AI), it analyses profiles and matches users with potential partners, whether romantic or platonic. The company has raised JPY 560 million ($3.8 million) in funding, underscoring growing investor interest. n nAgeing unlocks new market opportunities n nThe World Economic Forum’s Longevity Economy Principles: The Foundation for a Financialally Resilient Future highlights maintaining health and ensuring social connections as essential in longevity societies or precisely the areas where senior-focused markets are growing. n nJapan’s experience as the world’s most aged society illustrates the potential for innovation and the creation of new services within the longevity economy. It also offers valuable insights for countries facing rapid aging, providing guidance for building a sustainable and resilient future. n nDon’t miss any update on this topic n nCreate a free account and access your personalized content collection with our latest publications and analyses. n nSign up for free n nLicense and Republishing n nWorld Economic Forum articles may be republished in accordance with the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International Public License, and in accordance with our Terms of Use. n nThe views expressed in this article are those of the author alone and not the World Economic Forum. n nStay up to date: n nAgeing and Longevity n nRelated topics: n nMore on Sustainable Development n nSee all n nWhy agentic AI presents a turning point for business resilience n nManoj Mehta n nSeptember 15, 2025 n nMind the adaptation gap: Despite rising climate costs, few companies have adaptation plans n nTrade Compliance for Leadership: Navigating a Shifting Global Landscape n n7 hours ago n nWhat a game of Two Truths and a Lie can teach us about humanitarian aid n nFive years to go: Are we on track to meet the Sustainable Development Goals? n nRedefining the sovereign’s role in blended finance for sustainable development
