There is a phrase (甲牛年) that mentions the year 694 written on the Shumidan (a platform or dais for Buddhist image) part of the excavated Ogata-tason-senbutsu (a large clay tile with many Buddha figures), and it is thought that the temple itself was also erected around this year
発掘された大形多尊塼仏の須弥壇部分に「甲牛年□□中」（694年）の表記があり、寺の建立についてもこの年の前後とみられている。
