The main themes of the Doctoral program are a detailed advanced description of language, the construction of linguistic theory and verification of the theory by internal and external evidence. In the master's program, documents written in Japanese and four foreign languages (English, Spanish, Chinese, and Korean-each of which is offered as a major at the university) are used for the direction of education and research. In the doctoral program, language specialists excluding those in the aforementioned languages are admitted as, in order to contribute evidence towards the theoretical linguistics research aimed at the construction of Universal Grammar, we need to look above and beyond those langauges. As for external evidence, experiments concerning language acquisition and speech impediment, neuro-linguistics, and verification by means of language processing by computers are promoted as a promising directions in research.

The Doctoral program is designed to foster research on theoretical linguistics, the theory of language acquisition, the theory of language education, as well as advanced research on the grammar of each language. The academic training in the program must be useful and indispensable for talented people who have an important role in various interdisciplinary fields.
