Japan has a problem that has nothing to do with demand or technology: its business owners are getting old, and many have nobody to hand the company to. Government estimates have long warned that around 1.27 million owners aged 70 or over could be without a successor, and that roughly half of the firms at risk of closing are profitable. That gap between healthy businesses and missing heirs has made Japan one of the world’s most active markets for small-company M&A.
The size of the cliff
Japan’s Small and Medium Enterprise Agency first put numbers on the problem in 2017. It estimated that by 2025, about 2.45 million SME owners would be 70 or older, and that about half of them, some 1.27 million, had not decided on a successor. If those firms simply closed, it warned, Japan could lose around 6.5 million jobs and about ¥22 trillion of GDP.
The striking part is that many of these businesses make money. The agency has repeatedly found that more than half of companies that close voluntarily are profitable in their final year. Applying that ratio to the firms at risk is where the commonly quoted figure of around 600,000 profitable firms with no heir comes from.

|---|---|---|
| Owners aged 70+ by 2025 | About 2.45 million | SME Agency estimate |
| Of whom, no successor decided | About 1.27 million | SME Agency estimate |
| Voluntary closures that were profitable | More than 50% | SME Agency / SME White Paper |

Why the heirs are missing
Children no longer take over by default
For generations, Japanese family firms passed from parent to eldest son. Today, children often have careers at large companies or in cities and do not want to return to a regional factory, inn or distributor. Family succession has been falling as a share of all handovers, while succession to employees and outside buyers has been rising.
Owners waited too long
Many owners treated succession as something to deal with later. Finding and training a successor takes years, and owners who start in their late 70s often run out of time. Personal guarantees on company debt also make it hard for an employee to take over without family money.
The pattern is not limited to one industry
The problem appears in manufacturing, construction, logistics, retail, healthcare and food. We covered one example in Wagashi’s Succession Problem, where small confectionery shops are closing even though demand remains.
The policy response
- Support centres in all 47 prefectures — public business succession and handover centres match sellers with buyers and advise on valuation and process.
- Tax relief — a special succession tax scheme defers inheritance and gift tax on company shares when certain conditions are met.
- M&A guidelines and registration — the government has published guidelines for SME M&A and runs a registration system for advisers and intermediaries.
- Subsidies — grants help buyers cover advisory fees and post-merger investment.
From crisis to deal flow
Closing a profitable firm destroys value, so a market has grown to transfer these companies instead. According to figures reported from Japanese government data, deals handled by private M&A intermediaries rose from about 260 in 2014 to about 4,940 in 2024, while deals closed through public succession support centres rose from about 100 to more than 2,100 over the same period. Across all deal sizes, RECOF data put Japan-related M&A at a record of more than 5,000 deals in 2025.
Several types of buyer are active:
- Listed intermediaries — firms such as Nihon M&A Center, Strike and M&A Research Institute have built large businesses matching owners with buyers.
- Strategic buyers — larger Japanese companies buy suppliers, distributors and competitors to secure capacity and staff.
- Private equity and search funds — domestic and foreign funds buy owner-run firms and bring in professional managers. Search funds, where an individual manager raises capital to buy and run one company, have also taken root.
- Roll-ups — buyers acquire many small firms in one industry, such as building maintenance or dental labs, and combine back offices.
What foreign buyers should know
| Issue | What to expect |
|---|---|
| Valuations | Small firms often sell at modest multiples, but owners care about who buys as much as the price |
| Employees and customers | Keeping staff and long-standing customer relationships is usually a condition of the deal |
| Information | Books may be simple and mixed with the owner’s personal finances, so due diligence takes care |
| Personal guarantees | Banks must agree to release the owner’s guarantees, which can slow closing |
| Language and trust | A Japanese-speaking partner or local intermediary is usually essential |
Why it matters for overseas partners
- Market entry — buying an established Japanese firm brings licences, customers, staff and a brand at once, often faster than building from scratch.
- Supply chain security — many heirless firms are niche suppliers of parts, materials or know-how that foreign manufacturers depend on.
- Productivity upside — owner-run firms often run on paper and phone; digital tools such as freee and professional management can raise margins quickly.
- Policy tailwind — the government wants these companies to survive, so buyers who keep jobs and operations in Japan are welcome.
Conclusion
Japan’s succession cliff is a slow-moving demographic event, not a sudden shock. Each year more owners reach the age where they must sell, hand over or close. For buyers willing to respect the people and relationships inside these firms, it is one of the largest pipelines of profitable small businesses anywhere in the developed world.
