The Moyoro Shell Mound, a prominent archaeological site of the Okhotsk culture, has yielded numerous metal artifacts such as swords and spears. Due to prolonged storage, these artifacts have undergone significant deterioration, prompting the initiation of comprehensive conservation treatments in recent years. The conservation process includes preliminary investigation, cleaning, desalination, resin impregnation, and restoration, aiming to prolong the lifespan of cultural properties and enhance their stability and usability. The underlying philosophy of conservation is structured around three domains: conservation science, archaeology, and public engagement. Humidity control is critical in the storage and preservation of metal artifacts, and the use of data loggers, RP systems, and humidity control agents is recommended to prevent severe degradation. Environmental changes caused by exhibition and transportation also pose risks, necessitating careful consideration of climatic and humidity differences between Hokkaido and other regions. This study offers practical insights into achieving a balance between the preservation and utilization of cultural heritage.
