According to Masuoka (2003), there are three major descriptions of the Japaneselanguage: (1) school-level grammar, (2) Japanese grammar described from the viewpoint of generative grammar, and (3) Japanese grammar as the grammar of a foreign language.
In this thesis, I argue that the third position is the predicate-oriented view of Japanese grammar. This grammatical view provides the functional sentence patterns, which are more effective than the other grammatical concepts. Therefore, it is necessary that Japanese classes introduce descriptions from the grammatical viewpoint.
This grammatical concept was realized in five major sentence patterns of the Japanese language. These five sentence patterns were assumed in Sugai (1968), which was based on the research of Hayashi (1960).
