Theoretical issues in introducing a British traditional theory on constitutional conventions into the Japanese constitution

本研究的目的是通过对英国宪法理论的探讨，为日本宪法是否承认宪法惯例这一问题提供一些线索。首先，本研究为揭示日本宪法是否可以采纳英国传统的惯例理论提供了一个新的视角。第二，它建议与J. A. G.格里菲斯主张政治宪法，这可能会导致挑战一个相反的意见，强调在日本的宪法代码的存在。

The purpose of this research is to acquire some clues on the matter whether the Japanese constitution recognises constitutional conventions through an inquiry into British constitutional theories. In the first place, this research brought a new approach to reveal whether the Japanese constitution could adopt a British traditional theory concerning conventions. Secondly, it suggested that a dialogue with J. A. G. Griffith, who advocated political constitution, might lead to challenging a contrary opinion which emphasised the existence of a constitutional code in Japan.
