The Tokurenba Kofun stands on the eastern hills of the Tamatsukuri hot spring town, just north of the Izumo Tamatsukuri Museum. It is a small circular enpun (円墳) tumulus with a diameter of 8.5 meters and a height of 1.5 meters. Much of the mound has been eroded away, and a split bamboo-shaped sarcophagus (or boat-shaped sarcophagus) made of white quartz andesitic tuff is exposed in the centre of the burial chamber.
The sarcophagus has a total length of 2.3 meters and a width of 0.8 meters. The combination of lid and body is of the inroguchi style, with four hooks on the lid and two hooks on the body, which is rare in Shimane Prefecture.

It is said that an iron sword and agate beads were excavated from inside the sarcophagus, but these, and any other grave goods, have been lost.

The area around this tumulus was a centre for making magatama, round and cylindrical beads, from the end of the Yayoi period to the Heian period.
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.
