The purpose of this paper is to clarify the regional aspect of the usage of Kyōtsūgo Bunpō(common language grammar), which is parallel but not always congruent to the language of Tokyo. To do this, this study inquired into co-occurrence relation and meaning usage and the function, focusing on Epistemic Adverbs and Interrogative Forms recognized as Kyōtsūgo Bunpō(common language grammar)　especially in Eastern, Central, and Western Japan. The result clearly shows the fact that regional variations exist despite the variations according to adverbs. There have been many studies about dialect differences between eastern and western Japanese Archipelago, while this paper also ensures Kyōtsūgo Bunpō(common language grammar) differences among Eastern, central, and Western Japan. Consequently, it has now become apparent that even the adverbs of Kyōtsūgo(common language) used in the school texts and broadcasting have different nuances and usages depending on the geographical region.
