A large keyhole tomb in the Dainichiyama sector. The varied haniwa and Sue ware arranged on its eastern and western projections offer important evidence for funerary rites on the mound; the assemblage is a national Important Cultural Property.
Finds & research
Twenty-five haniwa and six Sue-ware objects from the projections and mound, with designated fragments, form the national Important Cultural Property assemblage; it includes a two-faced figure and a spread-winged bird. The chamber also yielded ornaments, weapons, armor, horse gear and tools.
Two views on the occupant
Archaeological view
Kii-Fudoki-no-Oka gives a mound length of 86m, or 105m including the base, for this two-tiered keyhole tomb. Built in the early 6th century, it has an Iwase-type corridor chamber over 7m long opening on the western side of the rear circle. Its two projections and mound yielded figural haniwa including a two-faced figure, a bird with spread wings and a raised-floor house, as well as Sue ware.
Imperial Household Agency view
Not an Imperial Household Agency mausoleum; a component of the Special Historic Site Iwase-Senzuka Kofun Group. The haniwa and Sue-ware assemblage from the mound and its projections is listed by the Agency for Cultural Affairs as a national Important Cultural Property designated on 17 August 2016.
Field notes
Official lengths differ: the prefectural museum gives 86m for the mound and 105m including its base, while the Agency for Cultural Affairs’ finds designation text states 141m. The agency and museum date the finds designation to 2016, but a prefectural heritage listing gives 2012. The chamber is normally closed but has opened for special events.
