Preserving Our Cultural Properties

Honkan

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.

Practical Research and Examination

Objects are surveyed in order to assess their condition. While continuing to research for information on the objects, aspects in the internal structures and materials used, that can not be seen by the naked eye, become clear. The results of these examinations are filed in an examination record.
