These huge statues are eight meters tall, and as a result of renovation carried out recently, documents were found inside the statues confirming that Unkei, Kaikei, Jokaku, and Tankei (Unkei's son) led many Buddhist statue sculptors specialized in carving smaller items to carve the whole thing in only two months, and it is also believed that Unkei was in charge of the entire production process.
造高8メートルに及ぶこれらの巨像は、平成の解体修理の結果、像内納入文書から運慶、快慶、定覚、湛慶（運慶の子）が小仏師多数を率いてわずか2か月で造立したものであることがあらためて裏付けられ、運慶が制作の総指揮にあたったものと考えられている。
