Asuka Yamaguchi, Associate Professor
Earth & Climate0 student voices
The Yamaguchi Lab studies deformation and material movement at subduction zones, where oceanic plates sink beneath other plates. Subduction zones are the largest shear zones on Earth, and they are also places where water and materials are transported on a massive scale. Deformation and material cycling there have a major influence on earthquakes and volcanic eruptions in the short term, and on the rise and decline of continents and on climate change in the long term. By combining deep-sea drilling, marine surveys, and onshore geological fieldwork, the lab seeks to approach these questions from both mechanical and chemical perspectives.

Masakazu Yoshimori, Associate Professor
Earth & Climate0 student voices
The Yoshimori Lab studies the mechanisms of global warming, polar climate, and past climate variability. The lab places importance on understanding climate as a whole by clarifying how the atmosphere, ocean, sea ice, and land surface influence one another. Its main tool is the climate model, a virtual Earth built inside a computer. In addition to numerical experiments, the lab uses observational data and reconstructed data of past climates to verify the reliability of its models.

Takehi Isse, Associate Professor
Earth & Climate0 student voices
The Isse Lab studies the structure of the Earth's interior through seismic observations on the seafloor. Oceanic plates are born at mid-ocean ridges and subduct at trenches, but reconciling theory with the actual Earth is still a work in progress. Using broadband ocean-bottom seismometers developed at the Earthquake Research Institute, the lab conducts observations in collaboration with researchers in Japan and abroad. From the records obtained, the lab aims to reveal the structure of oceanic plates and the deep Earth.

Yuichi Imanishi, Associate Professor
Earth & Climate0 student voices
The Imanishi Lab studies the interior of the Earth through gravity observations. Its field is geodesy, the science of measuring the shape of the Earth and its gravity. Using precise gravity observations with a superconducting gravimeter, the lab investigates the dynamics occurring inside the Earth.

Yasuyuki Kano, Associate Professor
Earth & Climate0 student voices
The Kano Lab studies earthquakes and natural disasters, especially phenomena that occurred in historical times. The lab investigates past earthquakes based on what is written in historical sources such as old documents. It collaborates with historians of Japan at the Historiographical Institute and carries out joint research across the humanities and sciences, under the banner of "history × earth and planetary science." The lab also takes part in running Minna de Honkoku, a citizen-participation project for transcribing historical documents.

Takao Koyama, Associate Professor
Earth & Climate0 student voices
The Koyama Lab uses electromagnetic and magnetic methods to study the subsurface structure of volcanoes and other areas. Its fields are volcano electromagnetism and solid Earth electromagnetism. Using electromagnetic and magnetic survey methods, the lab estimates the state of the subsurface and investigates how volcanoes prepare for eruption, as well as the eruption phenomena themselves. The lab also studies the dynamics of the Earth.

Yujiro Suzuki, Associate Professor
Earth & Climate0 student voices
The Suzuki Lab studies flows associated with volcanic eruptions, such as eruption plumes and pyroclastic flows. An eruption plume is a flow of volcanic ash mixed with volcanic gas. Because it mixes with the surrounding atmosphere through turbulence, how it moves is still not well understood. Using numerical simulations and laboratory experiments, the lab is attempting to directly reproduce full-scale eruption plumes on supercomputers. While aiming for a fundamental understanding of these phenomena, the lab is also involved in disaster prevention projects to reduce volcanic hazards.

Akito Araya, Professor
Earth & Climate0 student voices
To understand the Earth's internal structure and crustal activity, the Araya Lab develops new observation instruments and carries out observations with them. In particular, the lab uses state-of-the-art optical measurement technology such as laser interferometers. This allows measurements not only with high performance, but also in extreme environments such as deep underground or on planetary surfaces. The lab aims to reveal what kinds of phenomena can be observed in domains that could not be measured before.

Hisayoshi Shimizu, Professor
Earth & Climate0 student voices
The Shimizu Lab studies the magnetic fields of the Earth and other planets, and the dynamics of their deep interiors. Using geomagnetic and electromagnetic data from the Earth, the lab estimates the electrical conductivity structure of the deep mantle and the motion of fluid near the surface of the core. Using the theory of how the magnetic field is generated within the core, the lab also investigates how conditions in the lowermost mantle affect the motion of the core.

Nozomu Takeuchi, Professor
Earth & Climate0 student voices
The Takeuchi Lab is a global seismology lab that investigates the Earth's internal structure using seismic waves that travel through the entire planet. The lab develops new analysis methods to extract from seismic waves types of information that could not be obtained before, with the goal of broadening the framework of seismology. While using supercomputers to secure a large volume of data, the lab places importance on analysis based on close observation of the waveform data itself.
