Osaka Pref. Rock-cut tomb group

Takaida Yokoana Group

LocationOsaka Pref.
ShapeRock-cut tomb group
Period6th–7th c.

Overview

A National Historic Site where more than 100 horizontal rock-cut tombs are concentrated along river-terrace cliffs on the Yamato River. Believed to be the burial ground of immigrant communities from the 6th–7th centuries. Multiple tombs bear engraved wall images of human figures, boats, and horses, with noted similarities to Korean peninsula mural tombs. The site has international academic significance as evidence of the blending of immigrant culture with ancient Japanese society. Wall engravings (figures, horses, boats, concentric circles) reflect contemporary worldviews; the boat motif is interpreted as a "funeral boat" sharing motifs with Goguryeo murals. The establishment of this immigrant burial ground along the Yamato River documents the settlement process via river transport.

Finds & research

The High-field Yokoana cluster has been studied continuously since the 1930s. Large quantities of bone containers (kotsuzoki), pottery, ironware, beads, and metal goods have been recovered from the horizontal stone chambers. Many finds show continental influences. Multiple-interment burials (several individuals per chamber) are common. Incised wall carvings depicting human figures, horses, and boats are archaeologically notable. National Historic Site.

Two views on the occupant

Archaeological view
Believed to be the burial ground of immigrant communities from the Korean peninsula. More than 100 horizontal tombs have been identified clustered in the tuff and sandstone cliff faces along the Yamato River. The defining feature is wall engravings depicting human figures, boats, horses, concentric circles, and house shapes. Similarities to the painted tomb murals of Goguryeo (Korea) have been noted, and the leading theory attributes the site to immigrant clans. Finds include Sue ware, horse gear, and ornaments, confirming continuous use across multiple generations from the mid-6th to the 7th century.
Imperial Household Agency view
Not managed by the IHA. National Historic Site administered by Kashiwara City as the publicly accessible "Takaida Yokoana Park." Designated a National Historic Site in 1986. Yokoana-bo (rock-cut horizontal tombs) differ from keyhole mounds: they are burial spaces carved horizontally into cliff faces. This tomb type flourished in the later and terminal phases of the Kofun period (6th–7th centuries).
