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.
