TL;DR

By 2025, roughly 1.27 million profitable Japanese SMEs will have no successor to take over — putting decades of manufacturing know-how at risk of disappearing for good.

The Scale of the Shift

A quiet but massive tectonic shift is unfolding beneath Japan's economy. By 2025, the number of SME and small business owners over the age of 70 will reach approximately 2.45 million. Of those, roughly half—1.27 million companies—have no successor in place (1).

This is not simply a story about an aging population. According to SME Agency projections, if left unaddressed, a surge in business closures could result in a cumulative loss of approximately 6.5 million jobs and ¥22 trillion in GDP by 2025 (1). ¥22 trillion is the scale of an entire major industry disappearing.

The roots run deep. The average age of Japanese SME owners reached 60.7 in 2024, with the majority of owners now over 60 (2, 1). The craftsman-owners of the postwar boom generation—the backbone of Japanese manufacturing—are all reaching retirement at once.

What matters most is that many of the businesses closing are not failures. They are profitable, technically accomplished, and supplying components to major manufacturers around the world—yet they are being forced to shut down for one reason only: no one to take over. And what is lost is more than a company. Decades of machining know-how accumulated in the hands of a single craftsman, once broken, never comes back (1).

Seen differently, this crisis is also a historic moment of supply. The next article examines the paradox: why the world's finest small factories are closing while still in the black.
