Kakinoshima site
An expansive Jōmon-era archaeological complex in Hokkaido preserving shell middens and settlement remains from Japan’s prehistoric past.
At a glance
Kakinoshima is a substantial archaeological site spanning 92.749 square kilometers on Hokkaido’s southern coast. The site comprises large shell middens—refuse heaps from ancient food processing—alongside the structural remains of an adjacent settlement. Its scale and preservation make it a significant window into Jōmon life and subsistence patterns.
History
The site documents human habitation and activity during the Jōmon period, Japan’s long Mesolithic era. The shell middens testify to centuries of coastal resource exploitation, particularly shellfish gathering and processing. The adjacent settlement remains provide evidence of domestic life, community organization, and seasonal occupation patterns during this formative phase of Japanese prehistory.
What you see
Visitors encounter archaeological layers revealing the material culture of Jōmon communities. The shell middens—dense accumulations of discarded mollusk shells—form the most visible features. Excavated areas expose post holes, hearths, and artifact scatters marking habitation zones. Interpretive displays contextualize these remains within the broader settlement structure.
Cultural significance
Kakinoshima contributes essential data to understanding Jōmon settlement patterns, subsistence economies, and social organization. Shell middens worldwide offer archaeologists unparalleled stratigraphic sequences for dating and environmental reconstruction. This site’s extent and condition position it among Japan’s more informative prehistoric archaeological complexes.
