Research Overview

The ultimate purpose of my research is to illuminate the history of the Japanese Constitution in the modern age. Generally, the history of the constitution can be divided into three areas: the formation of the constitutional system, the operation of the constitutions, and the ideas and academic theories of the constitution. My research proceeds from the Meiji Era onward for operation of the Meiji-Constitution, and retroactively from the Showa Era for academic theories of the Constitution. For the former, I employ the empirical methods of historical science, referring to primary sources as much as possible. For the latter, I pay more attention to how the academic theories were inherited from the German jurisprudence, for which I will partly utilize the methodology of the comparative history of ideas.
In the area of religious law in Germany, there are many problems reflecting the unclear conditions after national reunification, and my research starts from present-day issues. In the future, I intend to study the historical development in this field and compare it with the relationship between State and religious bodies in modern Japan.
