At its essence, science searches for the fundamental principles and laws in the natural world through a "dialogue with nature." Starting with simple questions like "Why?" and "How?" we approach the mysteries of nature. What motivates scientific research is the desire for wisdom, the defining characteristic of human beings. Sometimes our understanding of nature is immediately applied to the real world; other times it brings about deep-seated changes in our lives over a long span of time.


Mathematics is an abstract discipline, but one that has universality and general versatility. By offering small-group studies and research that help the students both widen their understanding of the main trends of modern mathematics and prepare them for later research in pure mathematics or related fields, the Department fosters students who will use their education in mathematics to continue pursuing an academic career or play an active role in various other fields and areas of society.

Information Scienceexpand_more

Our aims are to approach through our research the essence of information processing — such as both the calculation of data and the cognitive processing of it — and to cultivate human resources who will develop more sophisticated and highly-functional computer systems by using the knowledge they acquire in the undergraduate program.

Information Science

Using the simplest fundamental laws, our aim is to achieve a unified understanding of Nature at its various scales, ranging from elementary particles, nuclei, atoms, molecules, materials, and living organisms, all the way to the Universe itself.


Students can learn about the most recent advances in astronomy, which is opening up new frontiers nowadays thanks to the great leaps being made in science and technology. Our courses offer systematic study in all the basic and necessary areas of astronomy. At the same time, through a wide variety of hands-on training activities, students acquire the skills to use advanced instrumentation and carry out practical course work and research.

Earth and Planetary Physicsexpand_more

Our department fosters an understanding based on physics of the various phenomena of the Earth and planets. Gaining a strong foundation in applied and theoretical physics, students learn basic analytical and experimental methods related to atmospheric and oceanic circulation, climate change, earthquakes, plate tectonics, and the evolution of the Solar System.

Earth and Planetary Physics
Earth and Planetary Environmental Scienceexpand_more

Our goal is to understand empirically the Earth and other planets, particularly the evolution and variation of their environments, as well as the beginning, evolution and extinction of life through analysis of the components of the Earth, geological layers, and fossils. Research is also conducted on the relationship of these evolutionary processes to the current global environment.

Earth and Planetary Environmental Science

The department's aim is to cultivate human resources who will be internationally-active and play leading roles in the future in the various fields of chemistry that search for, create, and understand the world of materials and life at the molecular structure and molecular assembly levels.

Biophysics and Biochemistryexpand_more

Aiming to understand the fundamental mechanisms of life, students study a wide range of biological aspects at the molecular level, such as gene expressions and regulations, signaling pathways, and protein structures and interactions.

Bioinformatics and Systems Biologyexpand_more

In this department, students learn about new fields in modern biology such as bioinformatics and systems biology, in addition to the basics of biological science and information science. Through course work combining programming (dry) and biological (wet) experiments, students are trained to be "bilingual" in both "wet" and "dry" experimentation.
