The Department of Intangible Cultural Heritage considers the manufacture of musical instruments, techniques for their repair, the manufacture of tools necessary for the production of the instruments and repair techniques, and the manufacture of materials necessary for these as important restoration techniques to support the traditional performing arts of Japan and has been conducting an investigation since 2017. This report is a sequel to the “Investigation Report on Techniques for Preserving Cultural Properties with a Focus on Musical Instruments 5” and provides an outline of seven cases of investigation conducted from February to December 2022. 　 Japan, pursuant to the Law for the Protection of Cultural Properties, has a system by which preservation techniques are selected, and holders and holding groups of these techniques are recognized. However, the present investigation has been conducted on holders and holding groups that are considered important regardless of selection or recognition. The content of the investigation has been organized into the following seven items in this order for each instrument: 1. Name of the holder of the technique, 2. Date of birth of the holder, 3. Address or place of investigation, 4. Date of investigation, 5. Investigator, 6. Overview of the holder, 7. Observation of the investigator. 　　 This year, as in the year before last, many conservation techniques for cultural properties were greatly influenced by Covid-19, and the necessity for investigation was felt all the more. Nevertheless, the investigation was not able to be conducted as scheduled due to the pandemic. Continuous attention needs to be given to both the current state of conservation technologies and the impacts of Covid-19.
