Methodological Relocation of the Constitutional History in the Occident and Japan-From the Viewpoint of Historical Source Research and Learning-History.

通过史料研究可以加深对宪政史的理解，史料研究考虑了史料产生和接受的语境，理论定位考虑了学术史的背景。这一认识是通过对以下专题的调查而获得的：对后罗马西方历史的认识框架、查理曼大帝的加冕、中世纪晚期和近代早期德国的城市政府、近代早期法国法院判决的渊源、1800年前后德国大学中的自然法理论、布伦纳的“土地”说和浅川宽一的“土地”说在学术史上的地位。

We can deepen our understanding of the constitutional history through the historical source research, which considers the context of the product and reception of the sources, and the location of the theories, which takes account of the background of the learning-history. This recognition has been acquired by the investigation of the following topics : the framework to recognize the post-Roman Occidental history, the coronation of Charlemagne, the city-government in late medieval and early modern Germany, the sources about the court decisions in early modern France, the theories of the natural law in the German universities about 1800, the theory of Otto Brunner about "Land" and the location of theories of Kan'ichi Asakawa in the learning-history.
