Kentaroh Suzuki, Professor
Earth & Climate0 student voices
The Suzuki Lab studies how clouds, rain, and particles in the atmosphere affect Earth's climate. Clouds both cool the Earth by reflecting sunlight back to space and warm it by trapping heat. Which effect wins out depends on the height and thickness of the clouds, and this is one reason why predicting climate change is so difficult. The lab investigates these cloud effects by combining analysis of satellite observation data with numerical models.

Hiroyasu Hasumi, Professor

The Hasumi Lab studies the large-scale currents that circulate through the world's oceans and the mechanisms of climate that operate through them. The ocean can store more than a thousand times as much heat as the atmosphere, so it is essential for understanding climate, which changes slowly and on a large scale. The interior of the ocean is difficult to observe, and many phenomena there are still not understood. The lab develops its own numerical models of the ocean and climate, and investigates ocean currents by reproducing them on computers.

Takashi Furumura, Professor
Earth & Climate0 student voices
The Furumura Lab studies how the strong shaking of great earthquakes is generated and how it travels through the Earth. The lab analyzes data from Japan's dense seismic observation networks, as well as seismic wave records from around the world. Using numerical simulations on supercomputers, it reproduces the characteristics of seismic waves traveling through complex underground structures. The lab reproduces the shaking of past great earthquakes to identify the causes of damage, and predicts the shaking and tsunami of future great earthquakes, with the aim of contributing to earthquake disaster prevention.

Kimihiro Mochizuki, Professor
Earth & Climate0 student voices
The Mochizuki Lab uses seismological methods to study earthquakes that occur where oceanic plates subduct. Most earthquakes, large and small, occur at plate boundaries beneath the seafloor. The lab deploys ocean-bottom seismometers on the seafloor for observation and investigates how fault slip begins and spreads. Its observations center on the subduction zones around Japan, and also cover subduction zones elsewhere in the world, including New Zealand.

Shingo Watada, Professor
Earth & Climate0 student voices
The Watada Lab studies solid Earth phenomena, including earthquakes, volcanoes, and tsunamis. Using data from satellites and from land-based and seafloor instruments, the lab aims to explain, from first principles, Earth phenomena that are still not understood. The lab treats the atmosphere, the ocean, and the Earth's interior as a single system linked by forces, and investigates atmospheric waves and tsunamis generated by earthquakes and eruptions.

Tatsuya Ishiyama, Associate Professor
Earth & Climate0 student voices
Ishiyama Lab studies active faults and the seismogenic faults that give rise to earthquakes. For active faults located undersea or along the boundary between sea and land, the overall picture, including their shape, distribution, and slip rate, is still not well understood. In addition to field surveys of topography and geology, the lab conducts research using methods that span several fields, such as numerical modeling and geophysical observation. Students can take on a wide range of problems, matched to their interests and strengths.

Mie Ichihara, Professor
Earth & Climate0 student voices
The Ichihara Lab studies the dynamics of volcanic eruptions and airwaves (acoustic waves emitted from volcanoes). Using methods such as theoretical calculations, analog experiments, and observations of airwaves, the lab aims to clarify how volcanoes erupt. The lab places great importance on fieldwork, and students can get hands-on experience with volcanoes all over Japan. The lab belongs to the Volcano Research Center of the Earthquake Research Institute.

Eitarou Oka, Professor
Earth & Climate0 student voices
The Oka Lab (Ocean General Circulation Research Group) studies the "ocean general circulation," the large-scale ocean currents that circulate around the world's oceans. The ocean general circulation transports heat, salt, nutrients, and more, and has a major influence on the Earth's climate and on marine ecosystems. Centered on observations from research vessels, the lab investigates the actual state of ocean currents and the mechanisms that drive them. The lab puts particular emphasis on research in the North Pacific, where the Kuroshio and Oyashio flow.

Oka Akira, Associate Professor
Earth & Climate0 student voices
The Oka Lab studies climate change over long timescales, both what has happened in the past and what could happen in the future. The ocean plays a major role in climate variability longer than several decades. In particular, circulation that includes the deep ocean affects the climate of the entire Earth over timescales of more than a thousand years. The lab reproduces this deep ocean circulation with climate models and ocean models, aiming to clarify the mechanisms behind its stability and variability. The lab also investigates the relationship between deep ocean circulation and the distribution of substances such as carbon in the deep ocean.

Chie Yokoyama, Lecturer
Earth & Climate0 student voices
Yokoyama Lab studies the mechanisms of clouds and precipitation by analyzing satellite observation data. The radar on the Global Precipitation Measurement (GPM) satellite captures even how rain is distributed in the vertical direction. Using that data, the lab has shown that heavy rain events that look alike can actually fall in several distinct patterns. The lab also links these findings to climate model projections to investigate how rainfall patterns will change as global warming progresses.
