The Amidaji Kofun cluster (阿弥大寺古墳群) is a group of three late Yayoi period burial mounds located in the Shimofukuda neighborhood of the city of Kurayoshi, Tottori Prefecture in the San'in region of Japan.

[1] The Amidaji Kofun cluster is located on the side of a hill overlooking Kokubugawa River.

This is a variation of the hōfun [ja] (方墳)-style square tumulus with polygonal-shaped protrusions on each of its four corners.

Parts of the slopes and protrusions were protected by river stones, similar to fukiishi.

Yayoi pottery, both ceremonial and for everyday use, was found around the protruding portions, but the burial chambers were not excavated.
