In 1997, since a private housing development was planned in an area north to this site, another excavation was conducted, when remains of cloisters on the northern border of the temple and of three buildings supported by hottate bashira (earthfast posts) were found, and research that followed recognized that a stylobate of a building to the north of the tower still remained.
さらに、1997年（平成9年）には、指定地域の北方で民間の宅地開発に伴い発掘調査が実施され、寺域北辺を画する回廊跡と掘立柱建物3棟が検出され、続いて実施された確認調査では塔の北側に建物基壇が検出された。
