Eiichi Tajika, Professor
Earth & Climate0 student voices
The Tajika Lab studies how the surface environments of Earth and other planets formed and have changed over time, and how these changes relate to the origin, evolution, and extinction of life. The lab focuses in particular on large-scale environmental changes linked to mass extinctions, such as global glaciation (Snowball Earth), asteroid impacts, and oceanic anoxic events. Its main method is numerical simulation using climate models and biogeochemical cycle models, and it also takes part in collaborative research involving field surveys and chemical analysis. Building on these findings, the lab investigates the conditions for habitable planets, including Mars, Venus, and planets outside the solar system.

Masayuki Ikeda, Associate Professor
Earth & Climate0 student voices
The Ikeda Lab studies how Earth's environment and life have influenced each other throughout geological time. In particular, it investigates how changes in insolation drive climate change, and how this relates to the extinction, adaptation, and evolution of dinosaurs, plants, and other organisms. The lab has also continued research on reading Milankovitch cycles from the striped patterns of bedded chert, a stratum formed in the deep sea. Through fieldwork, geochemical analysis, and analysis of the fossil record, the lab aims to uncover the causes and actual nature of major environmental changes in Earth's history.

Tomohiro Usui, Professor
Space, Particle Physics & Aerospace0 student voices
The Usui Lab is a planetary science lab at the Institute of Space and Astronautical Science (ISAS) of JAXA in Sagamihara. Planetary scientists, geologists, and remote sensing specialists work together to uncover the history of water in the solar system. The lab is involved in exploration missions such as Hayabusa2 and MMX, and analyzes samples returned from asteroids as well as meteorites. Members also go on field excursions to observe strata and rocks outdoors.

Ichiro Yoshikawa, Professor
Space, Particle Physics & Aerospace0 student voices
The Yoshikawa-Yoshioka Lab develops instruments for planetary probes and for satellites orbiting the Earth. The instruments observe, from a distance, the light emitted by planetary atmospheres and plasma. To understand how atmospheres formed and how they change over short and long timescales, the lab works on everything from instrument development to data analysis. The lab consists of two groups: the Yoshikawa Lab and the Yoshioka Lab.

Takeshi Imamura, Professor
Space, Particle Physics & Aerospace0 student voices
The Imamura-Aoki Lab studies the atmospheres of planets such as Venus and Mars, and the environments those atmospheres create. The lab's two faculty members play central roles in missions in Japan and abroad, including Japan's Venus orbiter Akatsuki, Japan's MMX (Martian Moons eXploration) mission to Mars, and Europe's Mars orbiter TGO (Trace Gas Orbiter). In addition to analyzing data from spacecraft and telescopes, the lab reproduces changes in planetary atmospheres through numerical simulations based on the theory of physics. Professor Imamura and Lecturer Aoki carry out research together and also supervise students jointly.

Tomokatsu Morota, Project Professor
Space, Particle Physics & Aerospace0 student voices
The Morota Lab studies how the surfaces and interiors of the Moon, planets, and asteroids have changed over time. Using data observed from a distance by spacecraft and other platforms (remote sensing data), the lab investigates these bodies with methods from planetary physics and planetary geology. The goal is to reconstruct the history of how the planets of the Solar System formed and evolved. The lab also takes part in exploration missions such as the lunar orbiter Kaguya and the asteroid explorer Hayabusa2, and puts great effort into observation operations and building data processing systems.

Takanobu Amano, Professor
Space, Particle Physics & Aerospace0 student voices
Amano Lab studies plasma phenomena found throughout the universe, mainly from a theoretical perspective. Even space that looks empty is in fact filled with tenuous gas, and much of it is thought to exist as plasma, a state in which the gas is electrically charged. The lab focuses on the elementary processes behind phenomena that occur everywhere from the vicinity of Earth to distant high-energy astrophysical objects. The lab often uses numerical simulation, and it also carries out theoretical work and analysis of observational data.

Imada Shinsuke, Professor
Space, Particle Physics & Aerospace0 student voices
Imada Lab studies the mechanisms of plasma heating and acceleration that occur in space. The solar atmosphere, Earth's magnetosphere, and interplanetary space are almost entirely filled with plasma. The lab focuses on magnetic reconnection and on how energy is transported by magnetohydrodynamic waves and turbulence. The lab also works on predicting the Sun's cyclic activity and on understanding the environments of the Sun and Earth at the time life emerged.

Seiji Sugita, Professor
Space, Particle Physics & Aerospace0 student voices
The Sugita Lab uses planetary exploration as a clue to study how the Solar System came to take its present form. The lab has worked on developing and operating the camera on Hayabusa2 and analyzing its data, investigating the history of the asteroid Ryugu. The lab is also developing measurement instruments to be carried on spacecraft for future missions to the Moon and Mars. Together with the Kasahara Lab and others, it conducts research as the Planetary Exploration Research Group in Faculty of Science Building 1.

Katsumata K, Professor
Environment & Sustainability0 student voices
The Ocean General Circulation Lab studies how the ocean's large-scale currents work, using observational data. Ocean flow is turbulent, yet at times it shows order, as in ocean currents. Motivated by the question of how such an ocean can be understood, the lab analyzes data collected by floats, ships, and satellites. The lab also focuses on the relationship between small-scale turbulent mixing and the circulation that spans entire ocean basins.
