Yusuke Suganuma (1977–) is a Japanese geologist and paleomagnetist who serves as an associate professor at the National Institute of Polar Research. His research focuses on reconstructing Earth's magnetic field and past environments from geological records, including sedimentary strata and lake deposits. He played a central role in the research team that secured international recognition of the Chibanian as Japan's first officially designated stage in the geologic time scale. His book "Geomagnetic Reversal and the Chibanian: Why Does Earth's Magnetic Field Reverse?" explains the science of geomagnetic reversals and the significance of the Chibanian in an accessible way for general readers.
