Earth and Planetary Sciences

Earth Environmental Systems

From a systemic perspective, we conduct inter- or trans-disciplinary research and education on the Earth’s environment that results from interactions between nature and human activities.

Geology and Geobiology

Based on traditional knowledge of geology and paleontology, this group carries out research and education concerning the Earth’s history on a long time scale.

Geochemistry and Cosmochemistry

Analyze the global environment, including human activities, using various chemical compounds, chemical elements and isotopes.

Earth and Planetary Physics

Explore the origin of the solar system and the evolution/changes occurring on the Earth and other planets by physically analyzing various phenomena.

Earth and Planetary Dynamics

Analyze and predict crustal activities such as earthquakes and volcanic eruptions, based on the latest observational and theoretical studies.

Chronology and Natural History

Chronological analysis, ranging from the targeting of natural samples, through to specific items related to human activities, as well as the collection, examination, classification and storage of various natural history samples.


Studies variation of life, animal behavior, and evolution of life in Archean. Research and education are based on field researches.


Hydrospheric-Atmospheric Sciences

Global Environmental Variations

The aim of this group is to elucidate past events through the analysis of samples obtained from glaciers and growth rings of trees, and understand the present situation.

Climate Science

Understand the various physical and chemical processes related to climate/global environmental changes, as well as to understand and predict further changes in atmospheric composition.

Global Geochemistry

Explore the mechanisms and dynamics of biochemical cycles in the atmosphere, hydrosphere and geosphere through field research, laboratory experiments and numerical analyses.

Global Water Cycle

Investigate processes associated with water circulation in the atmosphere, hydrosphere, and biosphere to improve the understanding of climate variations and environmental problems.
