Materials related to the art historian Tanaka Ichimatsu (1895-1983), who was the Director General of the Institute from 1952 to 1965, were donated by Mr. Tanaka Kazumi, the deceased’s family member, and the Idemitsu Museum of Art in March. Included among the materials are records of his research and photographs he collected. Even before World War II, Tanaka had investigated a great number of art objects and left carefully written reports with his own drawings attached. Among them are valuable reports on works of art that were lost during the War. Although these materials had been stored at the Idemitsu Museum of Art, with which Tanaka was closely related, they were donated to the Institute after his death in the hope that they may be made public and utilized more widely. We plan to make preparations for their utilization in the future. Since we have just begun to put them in order, anyone who wishes to see these materials are requested to contact the Department of Research Programming in advance.
