The Graduate School of Letters has established four divisions to foster highly skilled professionals and researchers who explore humanity by researching human activities and the culture produced by them.

The research subject is unknown activities of humanity and the culture produced by them. We have prepared an instructional system that allows graduate students to feel the satisfaction of a research project.

The Graduate School of Letters has four divisions, and its education and research philosophy is to understand the essence of humanity and human society by exploring the cultural and historical heritage built by humanity through its activities to help create a society richer in humanity.
The Graduate School of Letters has accepted international students mainly from Asia, including China, South Korea, Vietnam, Sri Lanka, Bangladesh, and Nepal, to date. Through information exchange and discussions about the cultures and regional characteristics of each others' home towns/countries in classes, students are able to experience differences in values and thinking among them and also gain new perspectives on Japanese culture.
In the Graduate School, research is an activity that enables graduate students to experience the satisfaction of unraveling the truth and reality in a close relationship with faculty members and involves the graduate students themselves identifying research topics, searching for materials and literature to unravel issues, and conducting field research and other activities. In the four divisions of the Graduate School of Letters, we emphasize the creation of an environment where graduate students can easily consult faculty members and provide detailed guidance so that graduate students can work on their research projects proactively and autonomously and feel the satisfaction of producing research results. Finding a way to solve issues that no one has been able to solve not only leads to the development of society but also to fulfillment and confidence in the graduate students.

In the Buddhist and Religious Studies division, graduate students research not only religions that are closely intertwined in people's lives and ethnicities and reflect human cultural activities themselves but also aspects that have strong influences on the values formed by society. For that reason, one could argue that religious studies, which leads to understanding of overseas cultures and regional characteristics, is becoming increasingly important for resolving a variety of issues in globalizing contemporary society.

In the History division, the major goal is to deeply understand the uniqueness of each country's history by conducting comparative research on the histories of Japan and a variety of countries around the world and viewing them from a range of perspectives, including cultural, economic, and political perspectives. This division also features substantial archaeological research, and graduate students are able to perform research from the perspectives of prehistoric and historical archaeology. With objects left behind by people who lived on the earth across various eras as a stepping stone, we are able to make inferences about life, cultures, and societies back then with the aim of applying what we learn in the present and future.

In the Studies of English Speaking Cultures Division, the major regions for research are the US, UK, and other large English-speaking regions, and we aim to foster individuals capable of playing active roles in globalized society through English linguistics, English and American literature studies, English pedagogy, and interdisciplinary regional studies of the English-speaking world. Deep knowledge of culture and history is indispensable for improving English communication skills. A characteristic of this division is that it enables graduate students to conduct interdisciplinary research from a variety of perspectives, including regional studies, cultural exchange, and cultural friction.

In the Studies of Japanese Culture Division, we strive to foster individuals who can appropriately communicate to the world information about Japanese culture by studying it comprehensively. This division is characterized by the ability to comprehensively understand diverse aspects of Japanese culture through the use of research methods and results from a variety of disciplines, including linguistics, literature, religion, intellectual history, art, sociology, and folklore. Students can also aspire to be the creators of new Japanese culture.
