This is a site located on a plateau at an altitude of 10 to 44 m on the left bank of the Niida River flowing north through Hachinohe City. The name Korekawa Site is a collective term for the Hotta Site (Middle Jomon period), Ichioji Site (Early to Middle Jomon period) and Nakai Site (Final Jomon period), and the Nakai Site is one of the sites representing the Kamegaoka culture.

The scale of the settlement is smaller than those of the Middle and Late Jomon periods, but various remains including a residential area, graveyard, processing area, dump and ritual place have been discovered.

A dump has been discovered under a mountain stream in a low-lying area in the Nakai Site. There were various kinds of food residues, such as the shells of Japanese horse chestnuts and walnuts, the bones of animals and fish, and shellfish in the dump. In particular, a large amount of Japanese horse chestnut shells have been unearthed, and the maximum thickness of the layer of accumulated shells was 80 cm. Lacquerware, gigs and other vegetable-based tools, which usually decay and do not remain, have been unearthed in the dump, and a water immersion facility to remove the bitterness of Japanese horse chestnuts was also discovered in the mountain stream.

The analysis of pollen, seeds and trees suggests that Jomon people managed useful plants in the settlement and its surroundings, and created an artificial ecosystem in a concentric fashion whereby an artificial forest is surrounded by satoyama (community-based woods) and then by natural forests in coexistence with nature.

A lacquering technique found in the Kakinoshima Site had been used not only to decorate tools, but also to strengthen them. In the Korekawa Site, discovered remains suggest advanced, systematic lacquer tool production activities, for example, Jomon people managed lacquer trees to draw their sap in the artificial forest and satoyama, and cut and processed the trees as wood material taking the timing of sap drawing into consideration.
