Unlike before the 2000s, when the focus was on the investigation and preservation of cultural heritage, the utilization of cultural heritage has come to the fore as a major issue since the 2000s. Such discussions are also the case with archaeological sites centered on buried heritage, and various discussions have recently been attempted on how to preserve and utilize archaeological sites preserved after excavation.
However, discussions on the utilization of archaeological sites are still primarily theoretical, dealing with the principles, purpose, and directionality of utilization, and a few studies that deal with concrete utilization plans also target archaeological sites from the historical period such as ancient tombs. This may be due to the differences in the types of relics and their remaining situations between archaeological sites from the historical period and prehistoric sites. In the case of archaeological sites from the historical period represented by ancient tombs, castles, building sites, etc., visible relics exist on the ground surface, so that the appearances, landscapes, or natures of the sites at the time can be inferred, although only partially. However, most prehistoric sites from the Paleolithic Age to the Early Iron Age have no structures remaining on the ground surface, and furthermore, in cases where their historical and academic value is recognized after the excavation investigation is completed and thus they are preserved or designated as historic sites, they are generally covered with soil to protect the relics, leaving only the terrains so that the scope of utilization of them cannot but be very limited.
In this paper, the utilization plan for the Songguk-ri site in Buyeo is examined. First, the preservation and utilization plan for prehistoric sites are theoretically reviewed, and thereafter, the cases of utilization of prehistoric sites in Japan are examined. Then, the existing case of utilization of the Songguk-ri site in Buyeo is examined, and thereafter, a utilization plan that can take advantage of rice farming, which is the characteristic of the Songguk-ri site, is proposed.
