The University and Original of the Japanese Constitution in Quantitative Perspective
(Winner of the 44th Ishiban Tanzan Award and the 34th Asia-Pacific Award Special Prize)
The Constitution of Japan, enacted in 1947, is the oldest unamended constitution in the world today. In my book, I examine why the COJ has lasted for over 75 years, despite periodic revisions being considered necessary for survival. Using quantitative data on constitutional design, I argue that the COJ's brevity, particularly on political institutions, has lessened the necessity for amendment, as most changes can be enacted through legislation. The book further explores the constitutional dilemmas caused by the COJ's lack of concrete stipulations, particularly on states of emergency and electoral rules. I conclude by examining Japanese public opinion towards constitutional change, based on original survey experiments. While support for amendments has increased in recent years, there is a remarkable lack of consensus on which provisions to change. This suggests the need for further bipartisan debate, not on whether constitutional change is necessary immediately, but rather on the ideal balance of human rights and political institutions to preserve the COJ into the future.
