Takao Hirajima, PhD
Dean and Professor

Welcome to the Kyoto University Graduate School of Science (GSS) website.


The GSS consists of Mathematics and Mathematical Sciences, Physics and Astronomy, Earth and Planetary Sciences, Chemistry, Biological Sciences Divisions.


In our history, we have supplied society with great talent of outstanding achievement in a range of research fields such as Novel prize or Fields Award winners. Lately we are promoting interdisciplinary research and education over and above creating a new academic area by launching a new educational program: “MAthematics-based Creation of Science Program” in 2016 and a center: “Center for Science Adventure and Collaborative Research Advancement (SACRA)” in 2019.


The nature of science is to explore principles of natural phenomena. We, as scientists, ponder over the essence of natural phenomena freely and fearlessly with unclouded mind, and pursue the truth rationally. You could say that most of the scientific discoveries that had huge impacts on the world had come out of scientists’ pure curiosity towards the principles of natural phenomena. Our brilliant faculty members, who have academic inquiring mind and various attractive personalities, are no exception and enthusiastic in discovery of the essence and the truth of natural occurrences.


I’m afraid that a recent trend to ask for easy-to-understand research contributions that are to be useful quickly seems to be growing. Most of us do hope that our research outcomes contribute to the society of course. However, in most cases, it would be difficult to make major discoveries only from such a short-term/local perspective. In order to reverse our way of thinking for making a significant breakthrough, you need a long-term perspective, a deep insight and enough time for research.


To our deepest regret, we acknowledged the research misconduct in the paper published by one of our faculty members in March 2019. I extend my heartfelt apology to the public and people concerned for it. Such an incident should not have happened at the university supported by public money. It is my sincere desire to try even much harder to enhance awareness against scientific misconduct hereafter.

To the current students

Even though we have well equipped facilities besides our brilliant staff with various charming characters, it is you whom we are most proud of. You are excellent students, who long for our academic culture, with limitless potential and diverse individualities. I expect you to discover new horizons through encounters with the right people, and gain a deep insight into the essence and the truth of things during your school life. In addition, I would like you to join us in making the school more attractive together.


Our undergraduate program offers you a wide range of options. The only required subject is the graduation work whilst you need to earn a certain number of credits from each subject cluster. Once you set your own goal, you will be able to make effective choices among the alternatives to take actions proactively toward the goal along your personal plan.


The other thing is that, I would like to advise you to keep in mind to talk with and listen to anyone around you now and then. Sharing ideas and exchanging opinions not only prevent you from being go-it-alone but lead you to find something new which might enable you to make progress in achieving the goal. If you have any trouble, you could also get professional counseling on campus. I hope you get to know who you are through those interactions.

To prospective students

We invite those who:

  • Make persevering effort to find solutions to problems with an excellent scientific background, high ability of logical and rational thinking and language skills.
  • Value academic freedom and are not afraid to challenge established authority or concepts, and are original thinkers with a mindset that embraces and produces novel ideas.

Please find details on the website of our admission policy.

To the faculty and staff members

Under severe fiscal circumstances, our job duties have been getting heavier and heavier. We have to streamline our operation for maintaining the quality of performance. This is one of the reasons why the SACRA was established. I embrace consensus building in steering GSS while making the SACRA well-functioned, and ask your cooperation for development of the school.

To supporters

As well as we seek the truth of natural phenomena retaining medium- to long-term vision, we strive to cultivate students’ scientific ground, develop their ability of logical and rational thinking and improve their eyes of perspective and mental strength.


On the other hand, during recent years, we face the downtrend in the scale of budget from the government and in the number of staff. In those harsh circumstances, your support truly helps us. We are deeply grateful for the support of donors.


Furthermore, we express our heartfelt apology for the research misconduct. We will continue to make our best efforts as a whole school to achieve high quality research results. We sincerely request your continued understanding and support into the years ahead. Please keep connected to us on our website or the Science Club Days.
