This book allows you to experience a wealth of primary sources. From the birth of radio broadcasting, covering baseball broadcasts to the Second Sino-Japanese War, to the Tokyo Olympics, Nihonbashi and expressways, and Goro Hani and Asahi Sonorama. It recreates the post-war Showa era of high economic growth, which was neither a beginning nor an end, with abundant historical materials. The narrative, which is not based on idealism, is not tiring to read. It allows you to relive the turbulent Showa era of high economic growth, rather than just reminiscing about it. This understated masterpiece by a contemporary unearths how the Heisei era was not the end or the beginning of Showa, but rather an era with a continuous connection. Focusing on the sound culture surrounding the 1964 Tokyo Olympics and the Shinjuku Folk Guerrilla, and the landscape issues of Nihonbashi and the Metropolitan Expressway, it explores the transformation of people's sensibilities in post-war Showa Japan with a fresh perspective.
