Preserving Our Cultural Properties
Our mission is to preserve the Tokyo National Museum collection which houses approximately 110,000 items of cultural properties. Preservation of cultural property involves balancing public access with conservation needs.
This requires a comprehensive approach which entails the precise application of preventive and remedial conservation in accordance with our long-term vision. We practice primary care as a comprehensive approach through regular clinical diagnosis, preventive measure and remedial treatment for cultural properties based on various experiences accumulated over the years and through latest research results.
