I am offering a complete set of the Shinto Archaeology lecture series, along with "Sacrificial Sites" and "Studies in Shinto Archaeology." Brief Biography of Dr. Iwao Oba Dr. Iwao Oba graduated from Kokugakuin University. After teaching at Yokohama Dai-ni Junior High School, he worked at the Research Section of the Shrine Bureau of the Ministry of Home Affairs. Later, he became a professor at Kokugakuin University. Known as an archaeologist, he studied folklore under Dr. Shinobu Orikuchi. At the Ministry of Home Affairs' Shrine Bureau, he was involved in surveys of various shrines and the editing of shrine records under Dr. Naoichi Miyaji. He was well-versed in archaeology, folklore, and historical document studies, and later established Shinto archaeology, which integrated these fields. In his early career, Dr. Oba was known as a researcher of the Stone Age, including his research on the Moroiso-style pottery and his co-authored work with Mr. Tsuneie Shibata, "Residential Sites of the Stone Age." However, after investigating the Izu Araitada site, he deepened his research in Shinto archaeology, conducting surveys of sutra mounds in Kumano, Kasuga, and Suwa, as well as sites such as the Kamizaka Pass and the Iriyama Pass, and various sacred mountains and iwakura (sacred rocks). These studies culminated in "Studies in Shinto Archaeology" and "Sacrificial Sites." Meanwhile, he also conducted research on a wide range of periods, including cave sites from various eras, the Yayoi period lowland sites of Sugao and Toro, the Jomon to ancient settlement site of Hiraide, and the Utsugi Mukaihara site, which was the impetus for naming the square moat tombs. In his later years, he compiled "Research on Ancient Clans from an Archaeological Perspective," which examined ancient clans based on the distribution of bronze bells, ancient tombs, and shrines listed in the Engishiki (a Heian period document). He also authored numerous introductory and general books, such as "New Lectures on Japanese Archaeology," "Matsuri (Festivals)," and "The Story of the Twelve Zodiac Signs."
