Overview
The Yōraku Kanjo Kofun (与楽カンジョ古墳) is a Kofun period square burial mound at the tip of a ridge extending south from the Kaibukiyama Hills, on the southern edge of the Nara Basin, in the town of Takatori, Nara Prefecture, Japan. It is one of the three largest tumuli of the Yōraku Kofun Cluster.
Its horizontal-entry stone burial chamber is 11.8 meters long and 5.3 meters high, the largest in Nara Prefecture. The mound is estimated to date from around the end of the 6th century to the early 7th century.

The Yōraku Kanjo Kofun is a hōfun (方墳) tumulus, 36 meters on each side and ten meters high, constructed in two tiers. A horizontal-entry stone burial chamber opening to the south has been confirmed. The chamber measures 11.8 meters in total length, with a dome-shaped ceiling and a particularly high chamber height of 5.3 meters, making it the largest in Nara Prefecture.
The chamber is constructed of huge diorite stones, with the relatively flat surface facing the interior. The left side wall is built in five layers and the right wall in four. The four walls are brought inward to form the dome-shaped ceiling, and the ceiling stone is a single monolith. The floor of the main chamber is covered with gravel.

The tumulus is estimated to have been built in the late to final stages of the Kofun period, around the end of the 6th century to the early 7th century. During a survey in 2015, pottery fragments dating to the late 7th century to the early 8th century were unearthed under the stone closing the entrance to the chamber. Since the mound is believed to have been built between the late 6th century and the early 7th century, a second burial is believed to have taken place around 100 years later.

The Yōraku Kofun Cluster consists of over 100 kofun lined up from north to south along a ridge, and excavations have been carried out there since 2002. The tumuli are estimated to date from around the end of the 6th century to the early 7th century, with post-interments confirmed up to the beginning of the 8th century. The three largest, the Yōraku Kansuzuka, Yōraku Kanjo and Terasaki Shirakabezuka tombs, are assumed to be the tombs of a toraijin immigrant clan, possibly the Yamato no Aya clan, on the evidence of miniature rice cooker pottery and dome-shaped stone burial chambers. These three tumuli were collectively designated a National Historic Site of Japan in 2013.

Tradition and region
About this kind of monument
Japanese kofun tumuli
Kofun are the great burial mounds of ancient Japan, built mainly between the middle of the third century and the early seventh century CE. The period takes its name from them. The most distinctive form is the keyhole-shaped mound (zempō-kōen-fun), with one square end and one round end seen from above, but there are also plain round mounds, double-rectangle mounds and square mounds. Orientation is not fixed: in the Mozu group at Sakai, some round parts face north and others east.
The largest is Daisenryō kofun at Sakai in Osaka, the biggest kofun in Japan, thought to have been built over some twenty years in the middle of the fifth century. By common acceptance it is the tomb of Emperor Nintoku, and the Imperial Household Agency treats it as such, but this cannot be confirmed because the mound has not been excavated. It stands in the Mozu group, which once had more than a hundred tombs of which fewer than half remain; the group and the neighbouring Furuichi cluster were inscribed on the UNESCO World Heritage List in 2019. The mounds were built on a plateau overlooking Osaka Bay, near the ancient coastline.
Dating rests on mound shape, pottery and grave goods. Haniwa, which means "clay circle", are terracotta cylinders and figures of houses, animals and people that were arranged in rings and rows around and on top of the mounds. Smaller kofun are very numerous and sit in groups in every region of Japan.
When visiting, look for the moat that surrounds the larger mounds, for the stepped outline of terraces, and for reconstructed haniwa in museums and parks beside the tombs.
