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.

The Meteorology Lab studies cloud physics, snow and ice meteorology, disasters and environmental problems in cold regions, and weather forecasting. It combines observation, numerical simulation, and data analysis to investigate the mechanisms behind meteorological phenomena. The lab deals with phenomena that appear on weather maps, such as extratropical cyclones and fronts, as well as small-scale phenomena such as cumulonimbus clouds and lightning discharges. The lab was newly established in 2017 and is actively adopting new methods such as machine learning.

The Ocean and Climate Physics Lab studies the motions of the atmosphere and ocean that shape Earth's climate. It examines phenomena at a range of scales, from regional to ocean-basin to global, and from day-to-day weather changes to climate changes over about a hundred years. The lab analyzes satellite observation data and the results of large-scale numerical simulations to discover new phenomena and explain their mechanisms. It also pursues interdisciplinary research with other fields, such as mathematical science and biogeochemistry.

The Space Geodesy Lab studies changes in Earth's shape, gravity, and rotation. Its tools are space geodetic techniques such as GPS/GNSS, very long baseline interferometry (VLBI), satellite laser ranging, and interferometric synthetic aperture radar (InSAR). The lab considers what these tools can do and applies them to earthquakes, volcanoes, and tectonics; to the atmosphere, oceans, terrestrial water, and snow and ice; and even to the Moon and Mars. Its research is not limited by region: the whole world, from the Arctic to the equator, is its subject.

The Seismology Lab studies phenomena occurring inside the solid Earth, such as earthquakes, volcanic eruptions, and plate motion. The subsurface is extremely hot and under high pressure, which makes it difficult to dig a hole and look directly, so seismic waves are one of the few clues available. Using its own seismic waveform analysis methods, seismic tomography, and numerical simulation, the lab makes use of waves ranging from short periods to very long periods. The scales it covers range widely, from familiar ones such as volcanoes and faults to continents and the entire globe.

The Evolutionary Paleontology research group studies geology, paleontology, and paleoenvironments based on fossils. The fossils it works with range widely, from dinosaurs to plants and cephalopods, and the group pursues the mechanisms of evolution and extinction and the relationships between organisms and their environments. The group places importance on going into the field and digging up fossils itself, and also uses the process by which organisms became fossils (taphonomy) as a clue in its research. The University Museum holds fossils mainly from Sakhalin and Hokkaido, and a great deal of research is carried out using them.

The Geochemistry research group studies a wide range of fields in Earth and planetary science, using chemical clues centered on isotopes (chemical tracers). The faculty in this group analyze meteorites and samples brought back from asteroids to clarify the origin and evolution of the Solar System. Using electron microscopes and mass spectrometry instruments, the group examines the elemental and isotopic composition of extremely small regions. The group also works on developing new methods and instruments for analyzing materials.

The Earth and Planetary Materials Science Lab studies, at the atomic level, the properties of the minerals that make up Earth and the planets. Minerals are the smallest units of the materials that make up Earth and the planets, and the many phenomena that occur there ultimately trace back to the properties of minerals. The lab synthesizes minerals itself under controlled conditions, aiming to clarify their physicochemical properties and the mechanisms by which they form. Because many ceramic materials are made of minerals, understanding the properties of minerals is also important from the standpoint of materials science.
