In this paper, I studied on “ichiban”, superative in degree adverb, for example “ichiban itta kuniwa dokodeuska”, and It was also considered about the difference with the degree adverb “totemo”. Under Nitta(2002) and Kudo(1983), “ichiban”, “totemo” was recognized as a pure degree adverb. But “ichiban” was stated about the difference which is “totemo” through a concurrence with a negative, the mood like concurrent restrictions, a concurrence with a specific word . when an adjective and limited verb kinds were modified, it was a called degree adverb, but when “ichiban” is used with a verb, what is modified is KOTOGARA. It is possible to be concurrent with various verb. The meaning of “the frequency of the movement, the number of the subject and the number of times of the target, etc.” is shown as the degree.
