The pagoda is a large quadrilateral structure called Ho-Goken (there are six columns on each of the four sides, with a space of five ken [about nine meters] between each column on the base layer) and it is highly possible that this was a nine-story pagoda as the tradition describes.
塔は方5間（初層平面の1辺に柱が6本立ち、柱間が5間あるという意味）の大規模なもので、伝承のとおり九重塔であった可能性が高い。
