Mozu-Furuichi Kofun Group (UNESCO)
Overview
A 110m keyhole mound managed by the IHA as a satellite of Konda Gobyoyama. 5th century, three-tiered. Among the larger satellite mounds, suggesting an occupant of high importance in the royal entourage. Located southwest of the main Ojin mausoleum, forming part of the core Furuichi landscape. The name "Futatsutsuka" (Two Mounds) suggests it was perceived as part of a paired mound group with a neighboring ancient burial.Constituent monument of the "Mozu-Furuichi Kofun Group" UNESCO WHS (2019). The satellite mounds of the Furuichi group tend to be larger than those of the Mozu group; the Konda Gobyoyama satellites include large keyhole mounds such as Hakayama (225m) and Futatsutsuka (110m). This raises the question of whether these are true satellites or lower-ranking independent mausolea—a significant scholarly debate illuminating the complexity of 5th-century burial institutions.

Two views on the occupant
Archaeological view
A keyhole mound (110m long) presumed to be a satellite of Konda Gobyoyama. 5th century. Among the larger satellite mounds; some researchers suggest it may be an independent powerful chieftain's tomb rather than a simple satellite. Three-tiered construction with surrounding moat is inferred, but no detailed excavation has been conducted due to IHA access restrictions. Located southwest of Konda Gobyoyama, forming part of the core Furuichi group area.
Imperial Household Agency view
Managed by the IHA as a satellite of Konda Gobyoyama Kofun (Emperor Ojin mausoleum, 425m). Designated and managed as an imperial mausoleum appendage. The name "Futatsutsuka" (Two Mounds) may derive from the paired recognition of this mound with a nearby neighbor, seen as a "double mound" by local tradition.
