Kanayama Kofun

Japanese: 金山古墳 - かなやまこふん

<br /> A twin circular tumulus located in Serutani, Kanan Town, Minamikawachi District, Osaka Prefecture. It was built in Serutani, a plateau measuring 1km east to west and 4km north to south, between the western foot of Mt. Katsuragi and the hills extending to the south of Tondabayashi City. It was designated a national historic site in 1991. The tumulus consists of two circular mounds, one large and one small, arranged side by side from north to south, the southern mound having an east to west diameter of 44.8m and a height of 8.2m, and the northern mound having an east to west diameter of 30.9m and a height of 7.2m. The length of the main axis of the mounds combined is 77.9m, almost equal to the sum of the diameters of the two mounds. Roofing stones can be seen on both the north and south mounds, and the perimeter of the mound is surrounded by rice paddies that are one level lower than the surrounding land. On the northern hill, a cave-in stone chamber and two hollowed -out house-shaped stone coffins with rope hanging protrusions were found. Details about the southern hill are unknown, and due to tomb robbery, only a few items have been excavated, such as glass beads, silver rings, horse equipment, iron swords, iron arrowheads , and pottery. However, based on the style of the stone coffin and grave goods on the northern hill, it is believed to have been built in the latter half of the 6th century, with a second burial taking place in the early 7th century, and it is said to be one of the very few twin circular tumuli that have neatly retained their original shape. Take the Kongo bus from Tondabayashi Station on the Kintetsu Nagano Line to Seriodani, and walk for about 3 minutes.

大阪府南河内郡河南(かなん)町芹生谷(せるたに)にある双円墳。葛城(かつらぎ)山西麓と富田林市南方に連なる丘陵との間にはさまれた、東西1km、南北約4kmの台地の芹生谷に築造された。1991年（平成3）に国の史跡に指定された。墳丘は大小2つの円丘が南北に並列し、南側の円丘は東西径44.8m、高さ8.2m、北の円丘は東西径30.9m、高さ7.2m。両丘を合わせた墳丘の主軸長は77.9mとなり、ほぼ両丘の直径の和に等しい。南北両丘には葺石(ふきいし)が認められ、墳丘の外周には周辺の土地より一段低い水田がめぐっている。北丘部分からは、横穴式石室と内部に置かれた縄掛突起を有する2基の刳(く)り抜き式家形石棺が確認された。南丘については詳細が不明で、出土遺物は盗掘を受けているため、ガラス玉、銀環、馬具類、鉄刀、鉄鏃(てつぞく)、土器類などわずかしかないが、北丘の石棺の形式や副葬品からすると、6世紀後半ごろに築造され、7世紀初頭ごろに追葬が行われたものと考えられ、築造当初の形状を整然と残したきわめて類例の少ない双円墳といわれている。近畿日本鉄道長野線富田林駅から金剛バス「芹生谷」下車、徒歩約3分。
