Yūda Funbogun

Yūda Funbogun is a megalithic mound in Yūda, Toga Town, Kamo District, Gifu Prefecture, Japan. It is a keyhole-shaped burial mound and forms part of the “Yūda kofun cluster,” a nationally designated historic site. The mound stands on a projecting hill east of the town center.

The uneven mound is 39.5 meters long, with an irregular circular rear measuring 24.5 meters across and a front section 15.0 meters long. Its front faces south-southeast. No stone facing or haniwa clay figures were found on the surface, although a dividing ditch survives only before the front. A wooden coffin was used for direct burial; it measured 2.6 meters long and 1.0 meters wide at the south end and 1.2-1.3 meters wide at the north end.

Excavations were carried out from 2009-2012. The burial remains have not been fully examined, but despite signs of looting, the coffin is considered to be preserved largely as it was at burial. Pottery fragments, including stands, jars and pots, were recovered from the mound.

The mound is estimated to date to the middle or first half of the 3rd century, within the broader period 250 CE to 650 CE. It is regarded as the oldest keyhole-shaped mound in the area and, together with Sugidō No. 1 and Hasuno No. 1, as among the earliest such tombs in the Tōkai region. Unlike the keyhole-shaped mounds previously known there from the late Yayoi period, it has a different character.
