New Book by Masamune Mimura, "Feedback Management," Goes into Fourth Printing Just Three Weeks After Release

U-ZERO Inc. (Headquarters: Chiyoda-ku, Tokyo; CEO & CPO: Masamune Mimura; hereinafter "the Company"), which supports employee engagement reform to enhance job satisfaction and eliminate unhappy workers, announces that its representative, Masamune Mimura's new book, "Feedback Management: From 'Silent Organizations' to 'Mutually Enhancing Organizations'" (Nikkei BP), has gone into its fourth printing. This marks the fourth reprint approximately three weeks after its release on June 8. An event titled "U-ZERO DAY 2026," centered on the book's theme, is scheduled for July 15, and anticipation is growing ahead of its opening.

Features of the Book

1. Unveiling the Structure of "Silent Organizations" and Offering Solutions

The book categorizes the symptoms of organizational silence into six types and presents "Feedback Management," which consists of three pillars for their resolution. It logically explains the root causes of organizational issues, which have often been perceived intuitively, with concrete examples.

2. Transformation Practices from Six Company Executives

Part 5 introduces real-life cases from six companies (Sumitomo Pharma, KITZ, Fujitsu, Deloitte Touche Tohmatsu, AstraZeneca, and Yayoi) that have tackled feedback management. In each case, the executives themselves recognized the lack of employee voice circulation as a management issue and personally initiated reforms.

3. The Author Himself Created a "Silent Organization"—Born from Failure and Regeneration

When Masamune Mimura, the author, became the first president of Concur Technologies, Inc. in 2011, he inadvertently created a silent organization while pursuing immediate results. Through repeated dialogue with employees, he found a breakthrough in feedback.

Through continuous trial and error, and by engaging with feedback as a manager, he established a domestic record of seven consecutive years of first place in the Great Place To Work® Japan "Best Workplaces" ranking (medium-sized companies) starting in 2018. Simultaneously, Concur Technologies, Inc.'s performance improved, achieving a sales scale that was unusual for a foreign-affiliated IT company and second only to that in the US market.

This book systematizes Mimura's accumulated knowledge as "Feedback Management" and organizes the elements necessary for its practice, presenting them as a highly reproducible method.

4. Empirical Evidence Based on an Original Survey of 2,060 Full-Time Employees

An original survey of 2,060 full-time employees in Japan was conducted for the writing of this book. It clarifies the structural causes of "silent organizations" and the differences from organizations where employee voices circulate, adding empirical evidence to engagement reform.

Author Masamune Mimura's Comment

Since its release, we have received many passionate comments about the book. The fact that it has gone into four printings in less than a month since its release is thanks to everyone who has read the book and recommended it to others.

On July 15, we will hold "U-ZERO DAY 2026," which shares the same theme as the book. On that day, I will speak about what feedback management is and how to practice it, with concrete examples. I hope that the book and the event will be of some help to those who notice the "silence" in their own companies and are ready to take action.
