Gunma Prefecture is the heartland of the Tōkoku culture, which created the most significant number of ancient burial mounds in the Kanto region. Dr. Kizo Ozaki (1904-1978), an esteemed archaeologist and honorary professor at Gunma University, conducted excavations of over 270 burial mounds in the prefecture during the 1946 to 1970. Dr. Ozaki's research findings are currently preserved at the Faculty of Education of Gunma University, and his comprehensive excavation materials, consisting of archaeological artifacts, records, and photographs, are recognized as invaluable resources unparalleled nationwide.

    In November 2016, in collaboration with the Gunma Prefectural Museum of History, the Library and Information Technology Center at Gunma University held the exhibition "Dr. Kizo Ozaki: The Father of Burial Mound Excavations in Gunma - Discovering the History of Excavations and Surveys in Gunma Prefecture." The exhibition was highly acclaimed.
