Sachihiko Itoh, Professor
Environment & Sustainability0 student voices
Itoh Lab studies how changes in the ocean environment affect ecosystems and fishery resources. Photosynthesis in the ocean is supported by nutrients carried up from deeper layers, and the survival of fish eggs and larvae varies greatly depending on where ocean currents carry them. The lab combines observations made from research vessels in Japan's coastal waters and the North Pacific with computer-based ecosystem modeling and data analysis. Students can also join research cruises and learn while experiencing the ocean as a field site.
Kentaro Sakamoto, Associate Professor

The Sakamoto Lab studies how marine animals such as seabirds and sea turtles behave and live in the wild. The lab uses biologging, a method in which small data recorders with sensors are attached to animals to record the behavior of freely moving animals. The lab conducts field surveys along the Sanriku coast in Iwate Prefecture, studying streaked shearwaters that gather on uninhabited islands and sea turtles that arrive in summer. The large amount of recorded measurement data is analyzed by computer to interpret animal behavior.
Yoko Iwata, Associate Professor
Environment & Sustainability0 student voices
The lab studies marine animals that humans use as resources, focusing on the mechanisms behind natural fluctuations in their numbers and their survival strategies. The maturation and spawning of marine animals, the growth and survival of their offspring, and their migration all vary with the marine environment. The lab focuses on the reproduction and life history of cephalopods such as squid, as well as shellfish and fish, and also investigates the ecology of closely associated organisms. Through diving-based field surveys and rearing experiments, the lab places importance on direct contact with living organisms and careful observation.
Koji Hamasaki, Professor

The Microbiology group studies the functions of marine microbes and the roles they play in sustaining the global environment. Seawater is home to many invisible microorganisms, including viruses, bacteria, and protists. The group investigates microbial diversity and its relationship with the environment, as well as microbial metabolism that supports material cycling, from both basic and applied perspectives. Samples are collected from a wide range of seas in Japan and abroad, including both polar regions, through cruises on large research vessels and field surveys at marine laboratories.
Yuichiro Nishibe, Associate Professor

The Plankton Lab studies the ecology and physiological characteristics of plankton and micronekton that live widely in the ocean. It aims to clarify how marine ecosystems work and the roles these organisms play within them. The lab holds a weekly seminar where members present papers and research to one another, and it conducts joint research with faculty members within the institute, including those at the Center for International Collaboration. Lab visits and tours are accepted at any time, and online meetings are also available.
Kiyoshi Kikuchi, Professor

The Aquaculture and Stock Enhancement Lab uses genome information to study the natural evolution of marine organisms and the evolution driven by human hands (breeding). Based at the Fisheries Laboratory on the shore of Lake Hamana, the lab combines state-of-the-art bioinformatics with experimental biology, in which organisms are actually reared and studied. Its work includes the evolution of sex determination mechanisms in fish, breeding improvement using genomic prediction, and the history of wild fish and shellfish populations. The lab is recruiting undergraduate and graduate students as research colleagues, and undergraduates from other universities are also welcome to join.
Kazutaka Takahashi, Professor
Environment & Sustainability0 student voices
The Aquatic Biology and Environment Lab studies the taxonomy, ecology, and environmental adaptation of bacteria and phytoplankton living in water. Changes in the aquatic environment first appear in water quality and bottom sediments, and then in the lives and species composition of small organisms such as plankton and bacteria. Through both laboratory experiments and field surveys conducted aboard research vessels, the lab characterizes the features of aquatic environments. Based on this understanding, the lab aims to protect aquatic environments such as oceans and lakes.
Hajime Obata, Professor
Earth & Climate0 student voices
The Marine Inorganic Chemistry Group uses chemical methods to study how elements and substances circulate in the ocean (material cycles). Researchers board research vessels to collect seawater, seafloor sediment, and air samples, and use precise chemical analysis to examine their composition and isotopic differences. The world's oceans, including the Pacific Ocean, the Indian Ocean, and the Sea of Japan, are the lab's field sites. The lab aims to clarify how the ocean responds to global environmental problems such as carbon dioxide emissions, and what role it plays.
Koji Inoue, Professor
Bio & Life Sciences0 student voices
The Molecular Marine Biology Group studies the mechanisms behind intriguing biological phenomena in marine organisms, using genes and genomes. Since life first emerged, the sea has been the stage for the evolution of living things. Focusing on shellfish and corals from deep-sea hydrothermal vent areas, medaka and related fishes, and other organisms, the lab explores how these mechanisms have evolved and what they mean within the organisms' ecology. The lab encourages anyone interested in its research to visit and talk with its members in person.
Katsufumi Sato, Professor
Bio & Life Sciences0 student voices
Sato Lab studies the behavior, physiology, and ecology of marine animals, with a strong emphasis on field research. Animals that live in the vast ocean and dive deep are hard to observe, so the ecology of many aquatic animals has remained poorly understood. To address this, the lab uses biologging: small data loggers are attached to animals to record dive depth, swimming speed, body temperature, and more. The lab studies a wide range of animals, from sea turtles in the tropics and penguins in the polar regions to fish and seabirds around Otsuchi, Iwate Prefecture.
