Korekawa ruins - Korekawa ruins

Japanese: 是川遺跡 - これかわいせき

A group of Jomon period ruins located in Korekawa, Hachinohe City, Aomori Prefecture. This name is a general term for Ichioji ruins, which mainly contain artifacts from the early and middle periods, Hotta ruins, which are from the late middle to late period, and Nakai ruins, which are from the final period, but it is often the Nakai ruins that usually refers to them. The ruins are located on the gentle slopes and river terraces on the left bank of the Niida River, which flows north from northern Iwate Prefecture. Nakai ruins was located in the villa of the wealthy Izumiyama family, and was excavated from the mid-Taisho period to the early Showa period, with the investigation by the Oyama Prehistoric Studies Institute in 1928 (Showa 3) being particularly famous. Excavated remains include various pottery commonly known as Kamegaoka style, as well as red lacquered bows, decorated swords, combs, and lacquerware on a pedestal. In addition, wooden spatula-shaped products, high-rises, woven fabrics, and other plant-based products, as well as various seeds and nuts, were found in the peat layer, indicating the high level of cultural content in the late Jomon period. Ichioji Site is also a model site where a large number of cylindrical pottery from the early and middle Jomon periods was excavated in 1926 (Taisho 15) and 1929 (Showa 4) by Tohoku University and the Oyama Institute of Prehistory Studies, respectively, was used to establish the type and chronology of cylindrical pottery. At the Hotta Site, the remains of a pit dwelling and a stone collection site from the end of the middle Jomon period were discovered in a 1972 (Showa 47) excavation. These three ruins were designated as a national historic site as the "Korekawa Stone Age Site" in 1957. The Hachinohe City History and Folklore Museum is located on the site.

青森県八戸(はちのへ)市是川に所在する縄文時代の遺跡群。この遺跡名は、前・中期の遺物を主体とする一王寺(いちおうじ)遺跡、中期後半より後期に至る堀田(ほった)遺跡、晩期の中居(なかい)遺跡に対する総称であるが、通常は中居遺跡をさす場合も多い。遺跡は岩手県北部より北流する新井田(にいだ)川の左岸丘陵緩斜面および河岸段丘上に位置する。中居遺跡は素封家泉山家の別邸にあり、大正中期から昭和初期にかけて発掘され、なかでも1928年（昭和3）大山史前学研究所の調査が有名である。出土遺物は通称亀ヶ岡(かめがおか)式といわれる各種の土器のほか、丹漆(にうるし)塗りの弓、飾り太刀(たち)、櫛(くし)、籃胎漆器(らんたいしっき)に加え、篦(へら)状木製品、高坏(たかつき)、編物などの植物性製品や、各種の種子、木の実が泥炭層から発見され、縄文晩期における文化内容の高さを示している。また一王寺遺跡は、1926年（大正15）東北大学、1929年（昭和4）大山史前学研究所の調査によって、縄文前・中期の円筒土器が多数出土し、それをもとに円筒土器の型式と編年が確立されたモデル遺跡でもある。堀田遺跡は、1972年（昭和47）の調査で中期末の竪穴(たてあな)住居跡や集石遺構が発見されている。これらの3遺跡は、1957年「是川石器時代遺跡」として国史跡の指定を受けている。遺跡地に八戸市立歴史民俗資料館がある。
