Labor shortages, geopolitical risks, and the generative AI revolution—in an era where “there may be no future just a few years from now” if nothing changes, who will drive growth?
The answer: approximately 9,000 companies that have moved beyond small business status and continue to grow.

This definitive volume thoroughly analyzes the growth strategies of “mid-sized companies” — which are widely seen as “the key to saving Japan” — through real-world case studies of 11 firms across the country.
It also presents first-hand insights from top executives at companies such as Japanet and Unicharm, along with commentary from the Ministry of Economy, Trade and Industry and analyses from academia.

“I don’t want to stay at this scale forever, but I can’t see the right path forward.”
This is a must-read for growth-oriented business leaders, successors, and executives who feel this way.

Not with abstract theories, but in practical language that works in the field.
Presented in a way that makes it personal.
A true “textbook” for reaching the next stage of growth.
