This book was planned to coincide with Yusaku Maezawa's birthday. Originally, it was conceived by Yusuke Mitsumoto (entrepreneur), Shinji Hamawazu (founder of NOT A HOTEL Co., Ltd.), and Yuki Terase (Mr. Maezawa's art advisor), who planned to gather testimonies from 50 close associates and present it as a surprise for his 50th birthday. However, after its creation, it was felt that this was not just a gift for him, but also something insightful for many people, and that it was worth reading, so it was decided to publish it. I have edited many business books, but most autobiographies and success stories have the person themselves speaking, and the editor creates the context with a predetermined conclusion. There is inevitably bias and convenience involved. In this book, by layering the voices of those around him, we tried to portray the person Yusaku Maezawa in a more three-dimensional way. I tried to be as careful as possible to avoid it becoming a hagiography. We asked them to speak without reservation, so it includes the negative aspects and contradictions of Yusaku Maezawa. His unusual attention to detail can exhaust those around him, and his focus can turn into frustration, driving people away. While beautiful ideals and visions inspire people, behind them, there can also be a desire for control and arrogance. The enthusiasm is beautiful from afar, but harsh for those close by. It is in those contradictions that the interest in reading about a person lies. I think the madness of a person who achieves something is like this. There is neither good nor evil in it. Whether you follow Yusaku Maezawa's way of life or use it as a negative example, I hope this book will be a trigger to change the reader's life. Atsushi Minowa, Editor, Gentosha He created ZOZO, took it public, built a trillion-yen company, and went to space. A man who continues unprecedented challenges. This book, through the testimonies of 50 people and the subject's confessions, exposes the structure of the madness of a person who breaks through. Results are only found outside of common sense.
