Miidani Kofun Cluster
The  is a group of Kofun period burial mounds, located in the Yokachō Koyama neighborhood of the city of Yabu, Hyōgo in the Kansai region of Japan. The group consisted of five tumuli, four of which were collectively designated a National Historic Site of Japan in 1992. Overview
The Miidani Kofun cluster is located in the center of the Tajima region, on a hill on the left bank of the lower reaches of the Yagi River, at an elevation of 83 to 93 meters. The group consists of four small -style circular burial mounds, all of which have been considerably flattened by erosion, exposing the horizontal-type stone burial chambers. The No.2 tumulus was slightly oval, measuring 12 by 14 meters; the No.3 tumulus was even more oval at 13.5 by 9.5 meters, and had fukiishi. The No.4 tumulus and No.5 tumulus were more circular, with a diameters of seven meters and six meters respectively. The No.1 tumulus is located further to the west, and is not part of the National Historic Site designation. From grave goods recovered during an archaeological excavation conducted in 1983, it is estimated that the No.2 tumulus was built from the end of the 6th century to the beginning of the 7th century, the No.3 tumulus and No.4 tumulus were in the middle of the 7th century, and the No.5 tumulus was in the latter half of the 7th century. Some 103 items were recovered, including many examples of Sue ware pottery, iron rings, iron horse harnesses, and iron swords. Of especial note was an iron sword recovered from the No.2 tumulus, which an X-ray analysis at the Nara National Research Institute for Cultural Properties revealed had a Chinese calendar dated copper-inlay inscription corresponding to 608 AD. This is the same year that Ono no Imoko departed on the Third embassy to Sui China. The site is now a public park, and is located about 13 minutes by car from Yōka Station on the JR West San'in Main Line. Gallery
