Overview

A 210m-long keyhole mound at Tannowa in Misaki, one of the largest in the Sennan region. Its rear circle is about 115m across and its front section about 100m wide. Dated to the mid-5th century by the excavation report (the town history gives the first half of the 5th century), it has three tiers, a west-side projection at the constriction, and a moat. It is a National Historic Site. Tradition associates it with Ki no Oyumi no Sukune, but the archaeological occupant is unknown.

Finds & research

Stone facing and cylindrical, morning-glory, shield, cuirass, and house-shaped haniwa have been identified. A chest-shaped tuff sarcophagus lies in the rear circle, and the Nara National Research Institute for Cultural Properties' national cultural-property database records a pit-style stone chamber (its compendium data gives this as possible, noting that stones thought to be cover slabs were once exposed). The occupant remains unresolved.

Official status & archaeological view

Official status
It was designated a National Historic Site in 1922, with Misaki Town as the managing body.
Archaeological view
The second excavation report (Misaki Town Board of Education, 1978) dates it to the mid-5th century, while the town history (1995) gives the first half of the 5th century. A single moat surrounds it. A place-name tradition in the Nihon Shoki associates it with Ki no Oyumi no Sukune, but the occupant is unconfirmed.

Field notes

Misaki Town gives an approximately 15-minute walk from Tannowa Station on the Nankai Main Line. The Misaki Town Tourism Association also gives about 15 minutes on foot from Misaki-koen Station and lists no parking.
