The Organic Reaction Theory Lab is pioneering the field of "high-speed organic chemistry," which accelerates synthetic chemistry. For over 100 years, organic synthesis has relied on batch reactors, typified by the flask. This lab uses flow microreactors, in which solutions flow through micrometer-scale channels, as its reactors. It establishes reactions and synthetic methodologies that are difficult in flask chemistry, and uses them to create new functional molecules.

The Data Mathematical Science Lab studies the fundamental principles of “state changes,” such as chemical reactions and structural transitions of biomolecules, using mathematical methods. Grounded in real experimental data, the lab aims to create data-driven mathematical science that does not presuppose a model. By analyzing single-molecule observation data and microscope images and checking them against natural phenomena, the lab builds up the mechanisms of the hierarchy of living systems. Together with researchers at other universities, the lab also develops methods for analyzing Raman microscope images and collective cell motion.

The Diversity Biology Ia Lab studies taxonomy, phylogenetics, and biogeography, mainly of marine invertebrates. About 1.5 million species on Earth are known, but the actual number is said to be 10 to 100 times higher. Through field surveys, collection, and experiments, together with rearing experiments, observation, and analysis in the laboratory, the lab seeks to understand the diverse and complex world of living things. The main work now underway is descriptive taxonomy and molecular phylogenetic analysis of invertebrates.

The Field Ornithology Lab studies the ecology, behavior, and evolution of birds across the Japanese archipelago, from Hokkaido to Okinawa Prefecture. Centered on fieldwork, the lab combines acoustics, statistics, molecular biology, and other approaches. The lab values walking the field in person and observing the target species closely. The lab does not feel it must keep pace with every research trend, nor does it get swept along by them; it aims to build up data that will still be valuable 100 years from now.

The Tsunematsu Lab aims to clarify the mechanisms that regulate sleep and wakefulness, and the significance of sleep. If we sleep eight hours a day, we spend a third of our lives asleep. Even so, there is still no answer to the fundamental questions of what sleep is for and why we dream. The lab focuses on using mice to clarify why and how the fantastical dreams of REM sleep occur. Launched in April 2023, this new lab uses methods such as large-scale extracellular recording, optical imaging, and optogenetics.

The Soft & Wet Matter Lab studies "gels," the materials that make up living bodies. Apart from bones and teeth, living bodies are made of water-rich soft tissue, that is, gels. By synthesizing functional gels that mimic the structure of biological tissue and examining their properties, the lab tests where the remarkable functions of living things come from. The resulting gels are also intended for application as materials useful in medicine, starting with artificial cartilage.

The Cell Dynamics Science Lab studies how cells move together as a group and what shapes they form. Epithelial cells such as those of the skin stay firmly attached to their neighbors while moving in the same direction. The lab follows this mechanism under the microscope. It has also become clear that the stiffness and viscosity of the culture substrate, which serves as the scaffold for cells, change the shape of cell groups and the behavior of cancer cells. Bringing a physics perspective to biology, the lab investigates how three-dimensional shapes are formed and how cancer invasion works.

The Planetary and Space Lab studies the atmospheres, internal structures, and surface environments of Earth and other planets. Its methods are wide-ranging: observations with spacecraft and telescopes, analysis of exploration data, and large-scale numerical simulations. Three units—exploration and observation, origin and evolution, and modeling and simulation—carry out research and education together as one team. Students choose a primary supervisor according to the research they want to pursue, and carry out their research while receiving guidance and advice from multiple faculty members.

The Petrology and Volcanology research group studies phenomena related to magma and plate movements using materials science methods. Its research centers on fieldwork in Japan and overseas, magma synthesis experiments, and the analysis and chemical analysis of rock and experimental samples. The group also uses many new methods, including ultra-high-spatial-resolution analysis of rock microstructure, ultra-high-precision chemical analysis, and numerical simulation. The group has two subgroups, Volcano and Orogenic Belt, and covers a wide range of fields, from igneous petrology to metamorphic petrology, geochemistry, structural geology, and geochronology.

The Seismic Observation Lab studies the mechanisms of earthquakes and volcanic activity based on observations of earthquakes and crustal deformation. Data from several dozen observation stations across Hokkaido arrive in Sapporo in real time, and the lab uses them to monitor daily seismic activity. The lab values going out into the field to collect data in person, such as climbing active volcanoes like Mt. Tokachidake and Mt. Meakandake with equipment on their backs. The lab also takes part in international joint research with researchers in Russia and China, and in seafloor observations off the Pacific coast of Hokkaido.
