DBA or PhD: What’s the difference?

While PhD (Doctor of Philosophy) programs generally prepare students only for academic careers even in the field of business administration, DBA programs consider a little broader career paths including consulting and management. ICS offers a DBA degree that provides the theoretical and scientific foundation required for an academic career, while assigning a similar level of importance to business-related problem-solving and practical implications.

The DBA faculty, trained at many of the world’s top institutions, bring a wide range of deep expertise to the program through teaching and advising.

Is a DBA right for you?

Each year, the DBA program accepts a small but diverse group of both full-time and part-time students who reflect a diversity of professional backgrounds:

  • Full-time students typically come straight from a related master’s program (business administration, management science, psychology, economics, sociology, neuroscience, and others).
  • Part-time students normally include (1) business practitioners who currently teach at business schools and wish to earn a doctoral degree; most continue to work as they pursue their DBAs, and (2) business practitioners planning to move into academia.
  • We also welcome business executives who are strongly motivated to contribute to the business community through means such as writing, lecturing, and consulting.

Individual endeavor in a supportive learning community

The DBA program is a tutorial program that revolves around guidance in writing the DBA thesis. ICS offers a supportive learning environment with formal coursework and interaction with other DBA students and faculty, while the student engages in his or her own individual research initiatives.

Program structure and curriculum policy

The DBA program is a tutorial program that revolves around guidance in writing the DBA thesis. ICS offers a supportive learning environment with formal coursework and interaction with other DBA students and faculty, while the student engages in his or her own individual research initiatives.

A DBA thesis considers a set of theoretically consistent hypotheses using data that has been gathered and analyzed through social scientific approaches and methods. By presenting objective evidence and comparing the presented hypotheses with alternative hypotheses, the DBA thesis is essentially different from a general management book, which typically expresses ideas based on unsupported conjecture. Writing the DBA thesis puts the theoretical consistency behind the hypotheses, the feasibility of practical application, and the thoroughness behind the investigation, to the test.

The DBA program values independence in learning. As a DBA candidate, you’ll determine the course and nature of your own personal specialization, while learning to produce unique research at the leading edge of a management field. Your thesis will identify a research question and assess a range of theories and frameworks for resolving it. You’ll develop a set of hypotheses and explore/examine those using social scientifically rigorous approaches and methods. Once your thesis project is approved, you will qualify for a grant from the DBA committee to cover related expenses (maximum per DBA candidate: JPY 100,000).

Some DBA students serve as a research assistant (RA) or teaching assistant (TA) for their supervisor or other ICS faculty member, and/or conduct joint research with ICS faculty. ICS offers scholarship opportunity for full-time students if the student is not fully supported by an external agency such as MEXT. Full-time students are expected to commit to the program and to create and maintain an effective learning community. In addition, full-time students are strongly encouraged to work as a paid researcher of a well-funded faculty research project.

Curriculum policy

The purpose of the curriculum of the DBA Program in School of International Corporate Strategy, Graduate School of Business Administration at Hitotsubashi University (hereafter referred to as the DBA Program) is to cultivate (1) research capabilities with high communication skills that enable students to present creative research results not only to Japan but also to the world, (2) leadership skills that enable students to lead the "knowledge development" in the academic world on a global scale, and (3) a high level of research ethics to contribute to the sound development of the social sciences. In addition, it aims to cultivate insights into the problem consciousness of practitioners and a high awareness of the quality of the practical implications of research.

In order to achieve the above goals, the DBA program provides students with the opportunity to learn, through required and elective courses and seminars, a wide range of research results in the fields of commerce and business administration, from the classics to the most advanced, as well as research methodologies and analytical methods, including experimental methods, quantitative modeling, and quantitative and qualitative analysis approaches, including case analysis. Students will be able to learn a wide range of approaches. Students will complete and present a doctoral thesis as the culmination of their studies to receive their degree.

Required courses consist of those from the first year to the third year, those from the first year to the second year, and those in the first year only. These courses are the basis for theoretical construction of the thesis and are the foundation of the DBA. The elective courses are systematically structured to cover a wide range of methodologies in the disciplines of commerce and business administration and related fields to build a solid intellectual foundation and steadily enhance research skills. For the methodology courses, students will learn about the logic and applications of the methods - starting from understanding them, to be able to critique research articles that use them, and even to be able to write their own articles using them. In courses on research content (literature) in specific fields, students learn about the accumulated knowledge in the field up to the most recent frontiers, and aim to be able to think by themselves about how to expand that knowledge in meaningful directions. In the required and elective courses, students will be evaluated on the basis of discussions in lectures, presentations of assignments, and term papers.

Diploma policy

The Tokyo High School of Commerce and Tokyo University of Commerce, the predecessors of Hitotsubashi University, were institutions that nurtured not only human resources active in industry, but also outstanding researchers and educators in the fields of commerce and business administration. This tradition, through Graduate School of Commerce established in 1953 and the Graduate School of International Corporate Strategy (ICS) established in 2000, continues to remain cherished this day within School of International Corporate Strategy, Graduate School of Business Administration at Hitotsubashi University, inaugurated in 2018.

The objective of the DBA Program in School of International Corporate Strategy, Graduate School of Business Administration at Hitotsubashi University is to realize world-class high-quality research in the fields of commerce and business administration, and to train researchers who can actively contribute to industry as well as academia.

In order to realize high-quality research of a global standard, we need to cultivate (1) research capabilities with high communication skills that enable students to present creative research results not only to Japan but also to the world, (2) leadership skills that enable students to lead the "knowledge development" in the academic world on a global scale, and (3) a high level of research ethics to contribute to the sound development of the social sciences. In addition, we aim to cultivate insights into the problem consciousness of practitioners and a high awareness of the quality of the practical implications of research.

Our DBA alumni are active as faculty members at universities in Japan and abroad specializing in fields such as management, marketing, accounting, and finance, as senior researchers and consultants at public research institutions, private think tanks, consulting companies, and as managers of companies and start-ups. They are expected to contribute to society as researchers or business practitioners who can indicate genuine approaches to issues that industry faces by drawing insights gained from their own research, or expand the frontiers of knowledge in commerce and business administration by conducting original research based on their professional experiences.

DBA thesis requirement

To complete a DBA thesis project, students are expected to:

a. Present their DBA thesis proposal at Advanced Research Positioning
b. Secure approval from the DBA thesis committee
c. Successfully defend their thesis at the oral examination (DBA thesis defense)

The DBA coursework is designed to provide DBA candidates with a thorough and comprehensive training in methods of social research. The DBA thesis is the culmination of the DBA program in which candidates demonstrate their grasp of the subject matter and their ability to conduct independent research that contribute to expand the knowledge frontiers of human society.

Preparation for the DBA thesis begins with the thesis proposal. The student must first prepare a DBA thesis proposal, and defend the proposal in an oral examination in front of the DBA thesis committee. Successful defense of the proposal signifies that the thesis project is feasible and that it makes a contribution to research.

Candidates who have passed the proposal defense will continue on to conduct their DBA thesis research. Candidates will advance to the DBA thesis defense when the committee determines that they are sufficiently prepared. The successful completion and defense of the DBA thesis signifies that candidates have acquired the necessary skills to express their research work clearly in both written and oral languages.
