Tateokayama Kofun Cluster: Three Small Tombs and a Local Legend
Explore the story and archaeology of a little-known three-tomb group, while treating the burial identities as local tradition.
Verified site photographs are being prepared.Discover Tateokayama Kofun Cluster: Three Small Tombs and a Local Legend
North of Imai's village centre, Tateokayama is a small cluster of three circular burial mounds rather than a landscaped archaeological park. Soni Village's heritage plan places the group in the later sixth century and describes horizontal stone burial chambers. A story in the Kojiki and Nihon Shoki connects this part of Soni with Princess Metori and Prince Hayabusawake, and local tradition identifies two mounds with the pair. That association is a compelling way into the landscape, but it is not an archaeological identification of the people buried here.
Three mounds, not two legendary graves
Nara Prefecture records three late-period kofun at Tateokayama. The village's heritage plan describes three circular tombs, all with horizontal stone chambers, and places them in the latter sixth century. Local tradition associates the group with Prince Hayabusawake and Princess Metori, but the burial identities are not established facts. A 2015 village newsletter explicitly corrected a common two-tomb reading: the group has three mounds, even though the story names two figures.
Read what survives without entering a chamber
The same village plan describes mound 3 as the best-preserved example. Its stone chamber has an inner room about 3.55 m long and 1.5 m wide, with a passage about 1.85 m long and 1 m wide. The walls are built from natural stones and lean inward toward the roof. The 2015 notice says the chamber entrance is partly filled with earth and its interior could not be viewed; it also says the first two mounds had been partly altered during path construction. These are heritage observations, not an invitation to climb, clear vegetation, move stones or enter a chamber.
Keep the Kojiki story and the burial date distinct
The Kojiki and Nihon Shoki recount the escape of Metori and Hayabusawake toward the Soni area and their capture and death there. The prefectural heritage page explains why this narrative makes the mounds significant to the region. Yet Soni Village's public account says the mounds were built later than the reign attributed to Emperor Nintoku in the story. Read the episode as a literary and local-memory landscape, not proof that a named royal couple lies in a particular mound.
Find the information point before seeking the site
The prefectural heritage map provides an approximate location in Imai, not a surveyed visitor entrance. Its page was updated on 27 February 2026, but the underlying record is dated 28 November 2016 and provides no present visitor route. A January 2015 Soni Village newsletter reported that the education board had installed a guide sign east of the Soni B&G pool because visitors had difficulty finding the mounds. The sign's present condition, the approach, and whether visitors may enter the land are not confirmed. Contact Soni Village Board of Education's cultural-property desk before making a special trip; do not follow a pin across private or unmanaged ground.
Make this a quiet heritage stop, not a facility visit
The prefectural entry gives no standard visitor hours, fee, staffed reception or designated parking. No toilet, step-free path, current trail surface, chamber access or photography rule was verified. Stay on a clearly public route, respect nearby homes and school/pool activity, and ask before photographing people. If access cannot be confirmed, use the prefectural map and interpretive sources rather than entering the mound area.

Photo notes
No photo of the mounds or chamber has been licensed to MyNara. Do not enter, clear or move anything for a photograph. Ask the land manager before photographing from the site and avoid nearby residents, school/pool users and private property.
