About this site

Overview

The Futagozuka Kofun (二子塚古墳) is a burial mound of the Kofun period in the Yamaga neighborhood of the town of Taishi, Minamikawachi District, Osaka, in the Kansai region of Japan. It was designated a National Historic Site of Japan in 1956, with the protected area extended in 2019.

It is an unusual sōhō-fun (双方墳), shaped like two conjoined squares when viewed from above, with a total length of about 66 meters. It is estimated to date from the first half of the 7th century, the end of the Kofun period, into the Asuka period.

Futagozuka Kofun (Osaka)

Description

Sources for this section

The kofun is one of the Isonagadani Kofun Cluster (磯長谷古墳群), a group of 30 kofun, five of which have been designated as imperial tombs by the Imperial Household Agency. It stands on a hill at the foot of Mount Nijō in the Kongō Range, in the southeastern part of Osaka Prefecture.

Each of the two tumuli is 25 meters on a side, and they are connected in parallel along a northeast-southwest axis. The eastern portion is 4.8 meters high and the western portion 6 meters high, each with three tiers. No fukiishi or haniwa have been found, although there is evidence of a moat.

The horizontal-type stone burial chambers are almost the same shape and size in the east and west tumuli, and both open to the southwest. The surface of one chamber retains traces of plastered walls. Inside each chamber was a house-shaped stone sarcophagus of almost the same shape and size, with a semi-cylindrical lid stone with a protrusion for hanging by ropes. Each sarcophagus has a length of about 2.2 meters, a width of about 1 meter and a height of about 0.7 meters.

The tumulus was robbed in antiquity, and only some fragments of pottery and iron nails have survived of the grave goods.
