[Machine Translation] Yasuhito Endo, now 34 years old and a veteran soccer player, is still the "heart" of Japan's national team. Why did he "survive" to the end of the golden generation, which included such talents as Shinji Ono, Naoyasu Takahara, and Junichi Inamoto, and why did he stay in Japan instead of moving overseas? The book includes interviews with Endo himself, who has followed his own philosophy without hesitation, as well as more than 60 members of the golden generation, people in the soccer industry, and Endo's immediate family members. The author's nonfiction book is filled with numerous themes, such as the aloof character of the late-blooming genius Yasuhito Endo, the tumultuous soccer life and emotional struggles hidden behind the athlete-like personality, and the mental control that surprised even the people involved.
