The integrity of the serial property is based on archaeological remains that exemplify the cultural traits and site types of the ancient Jomon culture in northern Japan. The property is comprised of archaeological sites that show the initiation of sedentism and the eventual separation between the residential area and burial areas; sites that show the diversity of settlement facilities during the warm marine transgression period, as well as hub settlements that have ritual places; and sites that demonstrate the maturity of sedentism through stone circles, cemeteries, and settlements. The sites also include, to a degree, their interaction with the environment. The component parts of the serial property are of adequate size individually, and as a group they include all important archaeological remains that constitute settlements and ceremonial spaces as well as landforms or features showing their locations and environment. The serial property is protected by law and does not suffer from the negative impacts of natural disasters or large-scale developments. There are, however, several modern constructions, referred to as “non-compliant elements”, that have impacts on the views to and/or from the component parts. Plans to mitigate such impacts by planting tree covers, for example, or by removing the non-compliant elements in the future have been developed.
