Bone and antler fishing tools

Bone and antler fishing tools

This is a settlement site with a shell midden that was formed in the second half of the Initial Jomon period (approx. 7,000 BCE), and is located at the end of a hill at an altitude of 10 to 20 m on the right bank of the lower Gonohe River in the northern part of Hachinohe City.

The shell midden consists of four small shell midden blocks. The remains of approximately 30 kinds of shells, including common orient clams, onogai clams, and yamato-shijimi clams, have been unearthed from the shell midden, and more than half of them are kinds of shells that are found in the inner bay areas. Regarding fish, the remains of approximately 20 kinds including Japanese sea bass, Japanese black porgy and bonito have been discovered. Most of these are kinds of fish that are caught in the inner bay areas, but some are pelagic. Remains of three kinds of birds and nine kinds of mammals as well as a huge amount of pottery, stone tools, stone objects and clay objects have also been discovered. Many kinds of bone and antler objects such as combination fish hooks and open socketed harpoon heads have also been unearthed, indicating much fishing activity.

Shell middens were formed when the sea level reached the highest point during the Jomon transgression. This suggests increased settlement and adaptation to environmental changes at that time.

The people at the time are considered to have developed rod and harpoon fishing methods according to the marine resources that were available in the early phase of the Jomon period. This is an important site to know the livelihood and dietary habits centering on fishing and the natural environment at that time.
