Japan's succession crisis is open for business.

For decades, the idea of a foreign company buying a Japanese SME was close to taboo. Owners who had spent forty years building a regional business assumed they would hand it to a son, a senior employee, or — in failing health — close the doors and let the customer list scatter. Selling to a foreigner was not on the menu.

That has changed, and it has changed fast.

By 2025, roughly [VERIFY: 1.27 million] SME owners over 70 had no identified successor. The pipeline of healthy, profitable, decades-old businesses with no one to take them over is now so large that the cultural taboo has buckled. Foreign buyers, foreign-managed funds, and foreign-led roll-ups are being sourced into deals that would not have been shown to them a decade ago.

The buy-side infrastructure is already huge. Japan has [VERIFY: roughly 2,900] registered M&A intermediaries, plus the major listed players — [VERIFY: Nihon M&A Center, M&A Research Institute, Strike] — who run deal flow at industrial scale. Around [VERIFY: 65%] of mid-market buyout deals are now succession-driven. The deals are small by global standards, many in the ¥100M to ¥1B range, but that is the point. The volume is what makes the market.

The weak yen helps. So does Japan's [VERIFY: 55%] inheritance tax, which often makes selling the cleaner option for an aging owner with no heirs willing to take on both the business and the tax bill.

What foreign buyers get wrong is everything that happens after the price is agreed. Japanese sellers care about what happens to long-serving employees, to suppliers who extended credit during hard years, to the brand the founder spent a career building. The highest bid does not win these deals — the most credible commitment to continuity does. We have seen sophisticated buyers walk away from clean financial wins because they would not address how the founder's name appears in the entity going forward.

What follows is the practical version: how succession deals are sourced and run, what the cultural mechanics of approaching an aging owner actually look like, and where in the market the real opportunities cluster.
