This work attempts to clarify the classification of grammatical cases based on syntax. Combining with the research results of Takahashi Taro's theory, the grammatical cases are divided into three types: "grammatical cases related to predicates", "grammatical cases related to attributives", and "grammatical cases composed of coordinating particles". The special forms of grammatical cases are divided into two types: one is "toritate(とりたて) particle" the other includes "grammatical cases composed of adverbs" and "grammatical cases composed of compound case auxiliary words".
