Drawing on previously unpublished historical documents and testimonies, the book is extremely valuable not only as a management guide but also as a historical resource.

It’s not Steve Jobs or Bill Gates. The person Masayoshi Son said he most admired in the world was none other than his father, Mitsunori Son. “Ever since founding SoftBank, I’ve always thought that my father was the true first-generation founder. I’m not the founder, I’m the 1.5th generation, he always said.” (From the text) Mitsunori Son, who started out selling shochu from scratch, built his fortune by running a pachinko parlor. Masayoshi Son grew up watching him and is changing the world with the AI ​​revolution. This is a passionate record of the intersection of their bloodlines, ideas, and souls. His father, Mitsunori, always burned with a “never give up spirit” even as he faced discrimination and poverty as a Korean resident in Japan. From his example, his son, Masayoshi, learned the true essence of business and inherited his pride as a challenger. “You’re a genius,” “You can be the best in the world.” His father repeatedly told him these things and showered him with love, supporting the foundation of the SoftBank Group and influencing its management philosophy, “Making people happy through the information revolution.” And then, as his father passed away, his final days approached… Even after being diagnosed with terminal cancer, his father said, “I want to live for another five years,” and “There are still things I want to do,” so his son did everything he could to have him transferred to a hospital in Tokyo. His vitality astonished even his doctors. But then the time for farewell arrived. “I’m the 1.5th generation. My father is the real 1st generation,” says Masayoshi as he wails, revealing his deep respect for his father and the pride of a Korean resident of Japan who has made it through life. Through meticulous research and skillful writing, author Inoue Atsuo has portrayed one man’s way of life and the resolve of the man who inherited it. What is family? What is blood? What is conviction? This book will pose questions to the reader and leave a deep impression. This is a story that reveals the origins of Son Masayoshi, and a work of nonfiction that shows us what it means to live as a “1.5th generation.” Publication commemorative event summary
