keisuke Sato, founder and president of Wonder Storage Holdings, Inc. (headquartered in Sapporo, Hokkaido), is pleased to announce that his first book, "Clumsy Management" (Sogoho Shuppan), released on February 10, 2026, will be reprinted.

This book is a real-life management book that describes the 15-year history of Wonder Storage Holdings, which started up a home-care business in 2011 with very little capital and has now grown to 50 locations in Hokkaido, 7 businesses, and annual sales of 4 billion yen.

Book

An attitude that continues to honestly face the root of social and community issues.

Providing low-cost housing by utilizing vacant houses. Thorough cost reduction.

A hands-on approach that continues to respond to the problems at hand. No one should be left alone.

In this book, we also reveal the behind-the-scenes of the company's management, including the crisis of bankruptcy, financial difficulties, betrayals, errors in judgment, and a series of failures, which until now have rarely been discussed.

This is not a success story, but the essence of "management that puts down roots of trust.

Message from the Author

What I have written in this book is not a story of special talents or spectacular success.

It is about not running away even if you were scared. I am not talking about being clumsy, but continuing to do so. I have made a series of choices not to cheat. That's all.

All I did was fail, and I am still walking around lost. That is why I thought there were words I could convey.

This book is not a book that pushes you to do your best. It is a book that gently sits next to you and says, "That's okay.

If you are at a standstill somewhere in your life right now, I would be happy if this book could lighten your heart a little.

It is a record of the muddled, clumsy, and yet faithful management of one person who had no dreams and no self-confidence to build a 4 billion yen company in Hokkaido over a period of 15 years.

We hope this book will help you take your next step forward.
