Daiishi (base stone) length: 72.6cm, width:76.0cm, maximum length of tower diameter :57.0cm, total height : 125.7cm from the bottom of base stone to the Hoju(the jewel) on top.
It is a miniature stone stupa used as sutra case. The base stone is made of one large stone, with Tsukuridashi style (square projections on constricted part of some keyhole-shaped mounded tombs).
The body part is cylinder shape and carved with Sanskrit letters with circular pattern all around. It has a large Hozo (a mortise), and hollowed out inside.
Kasaishi(the coping stone), Seika(the flower-shaped support) and Houju(the sacred gem) are produced from a single piece of stone. Kasaishi is an equilateral hip roof style, and there is a large Hozo-ana (a mortise) underneath of it. Originaly, it was in the premises of Yakushi-do Temple in Mine, and it is said to be the tombstone of Mitsujo-shonin(a Buddhist priest) but it is not quite conclusive.
There is no inscription of foundation date.
However, it is presume to be built approximately the late Heian-period through examining the style of each parts, like lower main part on the lower base stone, thin eaves and the curve of the coping stone and the shapes of the sacred gem etc.
