Epochs	Jōmon period

Fudōdō Shell Mound is an archaeological shell midden associated with the Jōmon period discovered near coastal wetlands in eastern Honshu; the site has produced faunal remains, lithics, and ceramic assemblages that illuminate prehistoric subsistence and settlement patterns. Excavations have linked material culture at the site to broader networks involving contemporaneous Jōmon settlements, and comparative studies reference sites such as Sannai-Maruyama, Ōdai Yamamoto, and Torihama. The site figures in discussions involving scholars and institutions including the Tokyo National Museum, University of Tokyo, Kyoto University, and the Agency for Cultural Affairs.

Overview

The site was first identified during surveys that engaged researchers from the University of Tokyo, Kyoto University, and archaeologists associated with the Agency for Cultural Affairs, prompting comparative analyses with the Jōmon period record preserved at Sannai-Maruyama, Yoshinogari, and Oyu. Scholarly attention has framed the midden within debates about coastal adaptation evident at shell middens like the Torihama Shell Midden, Omori, and Kasori Shell Mounds, and has connected faunal lists to vertebrate studies conducted by institutions such as the National Museum of Nature and Science and the Hokkaido University. Conservation dialogue has involved UNESCO advisory literature, the Cultural Properties Protection Law, and municipal heritage planning by local boards of education.

Location and Geography

Situated on a Holocene terrace near estuarine channels, the site occupies a landscape comparable to the settings of the Sannai-Maruyama Site, Sanin coastal middens, and the Nishinoshima areas studied by the Ocean Research Institute. Proximity to larger centers such as Sendai, Fukushima, and Niigata situates the site within the maritime ecology that influenced Jōmon communities documented at Ōba, Shinano, and the Noto Peninsula. Geological context references Holocene sea-level curves developed by the Geological Survey of Japan and paleoclimatic models used by the Japan Meteorological Agency and the Research Institute for Humanity and Nature.

Archaeological Excavations

Fieldwork was carried out by teams from the University of Tokyo, Kyoto University, and regional boards of education, coordinated with the Agency for Cultural Affairs and supported by funding mechanisms similar to grants from the Japan Society for the Promotion of Science. Excavation seasons employed stratigraphic techniques comparable to those used at the Sannai-Maruyama excavations and the Oyu Ruins, with specialists in zooarchaeology from the National Museum of Nature and Science and lithic analysts trained at the University of Tsukuba. Findings were cataloged in collaboration with the Tokyo National Museum, and reports were discussed at conferences organized by the Japanese Archaeological Association and the World Archaeological Congress.

Site Features and Findings

Excavations yielded dense shell layers dominated by species comparable to those reported from the Kasori and Torihama middens, alongside bone fragments attributed to fish taxa studied by ichthyologists at Hokkaido University and mollusk assemblages analyzed by researchers at the National Museum of Nature and Science. Ceramics recovered show cord-marked temper and decorative motifs that echo typologies established at Sannai-Maruyama, Yoshinogari, and the Kita-Kanto sites; lithic tools include flaked stone implements consistent with assemblages from Ōdai Yamamoto and the Torihama craftsmen tradition. Botanical remains and charcoal have been subjected to analysis in laboratories at Kyoto University and the University of Tokyo, employing radiocarbon dating protocols used by the Research Center for Cultural Heritage and cross-referenced with sequences from the Shimōsa Plateau and Izu archipelago.

Chronology and Cultural Context

Radiocarbon dates place occupation phases within time ranges paralleled at the Sannai-Maruyama Site, Oyu Ruins, and the Jōmon layers of Hokkaido, informing models of sedentism, resource scheduling, and craft specialization debated by scholars at the National Museum of Japanese History and the University of Kyoto. Material culture links suggest exchange and interaction networks that have been compared to patterns identified at Yoshinogari, the Shimane coast, and the Kofun transition described in syntheses by the Agency for Cultural Affairs and academic presses at the University of Tokyo Press. Interpretations draw on frameworks advanced by researchers affiliated with the Japanese Archaeological Association, the Society for American Archaeology (in comparative contexts), and international collaborations involving the Max Planck Institute for the Science of Human History.

Preservation and Management

Site protection has been guided by the Cultural Properties Protection Law and municipal heritage policies administered by local boards of education, with conservation measures paralleling those implemented at Sannai-Maruyama and the Kasori Shell Mounds. Partnerships with institutions such as the Tokyo National Museum, University of Tokyo, and the Agency for Cultural Affairs have facilitated curation, public outreach, and exhibit planning akin to displays at the National Museum of Nature and Science and regional museums in Sendai and Niigata. Ongoing site management engages the Japanese Archaeological Association, UNESCO advisory frameworks when applicable, and academic collaborations supported by the Japan Society for the Promotion of Science.
