Exploring the nature of humanity based on a multifaceted approach to language research

Linguistic sciences, which have been making rapid progress in recent years, are expanding the range of phenomena to be analyzed and explained, with the potential for further internal breakthroughs. In the Department of Linguistics, students are guided by the belief that the study of the language of their specialization (English, German, French, Hispanic, Russian, Portuguese, Japanese) is inseparable from the study of general linguistic theory.

At the same time, the department is also enhancing applied language research related to general language theory, such as language education and research on speech-language pathology. Another feature of our program is that we have created an environment that provides intellectual stimulation for the development of research by inviting prominent scholars in various fields and accepting outstanding students from Japan and abroad. As a result of these efforts, many of our graduates are active mainly in educational institutions.


In the Master’s Course, students learn the basic concepts and methods of linguistics based on their knowledge of their major language, write a master’s thesis on a specific area, and acquire research methods and thesis writing skills. The primary objective of the Doctoral Program is to prepare a doctoral dissertation in three years. Entrance examinations are conducted by submitting a research plan and an interview, and selection is based on the appropriateness and feasibility of the content of the plan.

Program Features

Various Courses are offered

The program offers a wide variety of courses, including the required courses “Founds of Phonetics& Phonology” and “Foundations of Syntax,” as well as courses in applied linguistics and sociolinguistics. We nurture researchers with a wide range of backgrounds.

Take courses outside of your area of specialization

In the doctoral program, students can take courses outside of their major field of study in order to deepen their knowledge of their major language and the system of their field of specialization, while at the same time developing observational and analytical skills that are not limited to a specific field of study.

3 courses

Speech-Language and Hearing Research Course

The Speech-Language and Hearing Research Course aims to train leaders and researchers with a broad perspective and rich humanity through subjects ranging from basic theory to clinical practice (therapeutic education and rehabilitation) of communication disorders. By completing designated courses, students can obtain qualifications to sit for the national examination for Speech Language-Hearing-Therapists.

TESOL (Teaching English to Speakers of Other Languages) Course

This course is designed for current English teachers and those who wish to be involved in English education in the future, with the goal of developing more advanced practical skills based on theoretical knowledge of English teaching. All required credits can be earned in English.

Japanese Language Education Course

This course is designed for those who are interested in working in Japanese language education. Students will consider effective Japanese language education while conducting research on Japanese language acquisition. Students may also take other course subjects within the Graduate School. In addition, students can learn through practice as teaching assistants for Japanese language education on campus or as Japanese language instructors for international students. There are also opportunities to interact with students in Japanese language programs at overseas universities.
