On July 2, 2017 I will be leading Kōgakkan University 皇學館大学 students and faculty on a historical tour of sites along the “Old Road of Kumano” 熊野古道. As we leave Ise, we’ll pass by excavation sites for the “Kayama Tomb Mounds” 蚊山遺跡 (now known as the Sakori Tomb Mounds 左郡古墳群) and Iwade Castle 岩出城.
As with the Ochiai site, I’ve driven around the area, but as far as I can tell, there are no signs or other indications of exactly where the excavation site was (assuming it isn’t buried under the highway).
What Is It?
During excavations related to the construction of the expressway to Ise, objects dating from the Paleolithic Age (旧石器; 40,000 BCE to 14,000 BCE) to the Early-Modern
Period (近世; 17th to 19th centuries) were found. Among these, the “Kayama Tomb Mound” site, contained objects from the fifth century during Japan’s Tomb Mound Period (古 墳時代; 3rd to 6th centuries). These were dated one century earlier than the contents of the Ochiai site just across Miyagawa River. The “Iwade Castle” site was excavated later, and it contained roof tiles, pottery, and other objects from Japan’s medieval period (中世; 12th to 16th centuries).
