Mr. Tsuda Tetsuei and Ms. Sarai Mai of the Department of Research Programming will start this year to investigate and research important sculptures in Shiga Prefecture in a two-year plan, Investigation of and Research into Statues in Omi in Ancient and Medieval Times, Centering on Previously Undisclosed Statues such as Hidden Buddha Statues (representative researcher Tsuda Tetsuei). The two received funds for the investigation and research from the Idemitsu Culture and Welfare Foundation, and received cooperation from the research staff, who have special bonding with Shiga Prefecture, centered on Miho Museum. As our first project, we investigated the seated Avalokitesvara statue (245.3 cm high) at the Kannondo of Tendaishu Zensuiji Temple on Mt. Iwanesan in Koga City from the early morning until the evening of Sunday, April 26. The existence of this statue was generally unknown up to now, and this is the first project to move it. Based on the style of the statue, it was probably carved in the late Heian Period, and it was kept in relatively good condition. We were given a glimpse into the abundance and versatility of the cultural properties of Shiga Prefecture, where such a great work existed unnoticed by most people.
