80 years since its promulgation, attention is turning to the Constitution of Japan. That's why now is the time to seriously consider the Constitution – that's the theme of Koichiro Kokubun's latest book, 'Defeat to the Emperor: Philosophy Lecture Series' (Shincho Shinsho).
Under the Second Abe administration, laws such as the Act on the Protection of Specially Designated Secrets and the Security Legislation were successively enacted, leading to a situation that could be called a 'crisis of constitutional order.' However, an unexpected 'presence' stood in its way. Why did 'Defeat to the Emperor' occur? The reasons are explored by tracing back to the controversial 'post-war theory' from 30 years ago, the resistance from Showa-era constitutional scholars and literary figures, and war responsibility. This is a new frontier for the author, known for the bestseller 'The Ethics of Leisure and Boredom,' delving into the core of 'Emperor, Constitution, and Post-War' through a constitutional and literary theory lens.

【Author's Comment】
This book is the first time I, as a researcher of philosophy, have written on the theme of 'Japan.' I am challenging fields outside my expertise, such as the Japanese Constitution, post-war Japan, and Japanese literature. In that sense, I feel more tension than usual, but as someone who has been involved in 'discourse' in some capacity since 2011, I wanted to draw a line and have put my best effort into it.
■Book Content Introduction
80 years since its promulgation, it's time to seriously consider the Constitution of Japan. The narrative woven around the Constitution, while permeating the public consciousness, faced a crisis under the Second Abe administration. At that time, an unexpected 'presence' stood in its way – why did 'Defeat to the Emperor' occur? The reasons are explored by tracing back to the controversial 'post-war theory' from 30 years ago, the resistance from Showa-era constitutional scholars and literary figures, and war responsibility. This work examines the core of the complex entanglement of 'Emperor, Constitution, and Post-War' by comparing the attempts of post-war constitutional scholarship with modern literature.
