Genzaburō Yoshino (1899-1981) was a Japanese writer and publisher. In 1935, he became director of a collection of educational books for young people. Yoshino stepped in to write How Do You Live? when Yūzō Yamamoto, the expected writer, fell ill. Since its debut as a novel and guide to philosophy for young people, How Do You Live? has been re-edited and republished more than eighty times, a reflection of the changing times and culture in Japan.
