Publication of National Treasure: The Hikone Screen

The Hikone Screen, a report

 A report on the study of The Hikone Screen that was held jointly with the Hikone Castle Museum from 2006 to 2007 has been published. The work, which had been mounted as a framed work, was restored on full scale and remounted as a folding screen. Included in the report are photographs of the screen before and after restoration, and many high-resolution digital images, infrared images and luminescence images. Persons involved in the publication of this report made great efforts to provide as much information concerning this work of art as possible. For example, infrared images showing directions for the use of colors, which can be seen only underneath the paint layers, are compared with actual color images; data analyzed by X-ray fluorescence are compared with high-resolution data of corresponding points. We hope that this report may be utilized as fundamental material for the study of the screen. The report has been published from Chuo Koron Bijutsu Shuppan for the general public.

Investigation of the Hikone Screen

 The full-scale restoration of the Hikone Screen (collection of the Hikone Castle Museum), which took two years, was completed and the restored folding screen was exhibited to the public in a special exhibition held to commemorate the 40th anniversary of the construction of the castle. The Institute has held a joint investigation of the Hikone Screen with the Hikone Castle Museum from before the start of the restoration project. After the closing of the exhibition, photographs of the folding screen were taken and the condition of the surface that has been stabilized by restoration was investigated and documented by high-resolution digital images and near infrared images. A report on these results is in the final stage of editing for publication. New findings obtained through this investigation are expected to become valuable material not only for the study of the Hikone Screen but also for the study of the history of Japanese paintings as a whole.

 Since the previous fiscal year, the Institute has been conducting a joint investigation and research of the national treasure Hikone Byobu with the Hikone Castle Museum. For over 100 years, this painting had been disassembled and mounted as six separate panels. Moreover, there were stains and the pigment layer was progressively flaking. Due to these reasons, two years were spent in conducting full-scale restoration as a part of the System for Protecting Cultural Properties and under the guidance of the Agency for Cultural Affairs. As a result, the painting was remounted as a folding screen. Since the restoration has been completed successfully, an exhibition of the restored folding screen was held as a part of the memorial project for the 400th anniversary of the construction of Hikone Castle. Part of the results of optical investigation conducted on this painting was also introduced in large panels during the exhibition, which was held from September 28 to October 26. Detailed images that allow one to observe the delicate and microscopic expressions brought about by extremely outstanding painting skills as well as directions for colors and under-drawings invisible to the naked eye attracted many visitors and were well-received by them. Presently, a report on the results of the investigation is being prepared for publication by the end of this fiscal year.
