The Korekawa Site (是川遺跡, Korekawa iseki) is an archaeological site in the city of Hachinohe, Aomori Prefecture, in the Tōhoku region of northern Japan containing the ruins of a middle to late Jōmon period (3000-1000 BC) settlement.
The garbage midden contained the remnants of various shellfish, bones of animals and fish and an extremely large number of Japanese horse chestnuts and walnuts, indicating the importance of these nuts in the Jōmon period diet.
Many of the artifacts recovered from the site are on display at the Hachinohe Archaeological Institution - Korekawa Jomon Kan (八戸市埋蔵文化財センター 是川縄文館), a museum built at the site, which has been preserved as an archaeological park with several reconstructed pit dwellings.
In 2011, 330 items recovered from the site were designated as Important Cultural Properties by the Japanese government.
