"Yakushiji Engi" (The History of Yakushi-ji Temple) which was written at the beginning of the 11th century contains a description of Shofuku-ji Temple which was built at the wish of Oku no Himemiko (Princess Oku) in remembrance of her dead father, Emperor Tenmu in Nabari County, Iga Province, and it is supposed that Natsumi Hai-ji was that Shofuku-ji Temple.
11世紀の初頭に成立した『薬師寺縁起』に、大来皇女の発願により亡き父天武天皇を偲んで伊賀国名張郡に建立された昌福寺のことが書かれており、夏見廃寺はその昌福寺ではないかと考えられている。
