the highest elevation. It has a total length of 34 meters, with the anterior 14 meters long, 13.7 meters wide, 1.6 meters high, the posterior is 20 meters long, 19 meters wide, 4.1meters high, and the constricted part is 6.8 meters wide.

Mound No. 10 is then only dome-shaped tumulus in the groups, and has a diameter of 20 meters and a height of 4.3 meters. The remaining are square tumuli. No.6 is representative of the remaining tumuli, and has a long side of 15.4 meters, a short side of 12 meters, and a height of 3.3 meters. 6. The (2,452 square meters) is one of the oldest and the fourth largest two conjoined rectangle-shaped kofun (zenpō-kōhō-fun (前方後方墳)) in Toyama Prefecture. It has a total length of 58 meters. The anterior portion is 27 meters by 26 meters and 3.6 meters high, and the posterior portion is 31 meters by 33 meters with a height of 7.6 meters. As the mound is considerably weathered, it may have originally been even larger. There are traces of a moat. This kofun has never been excavated, so its interior structure and the presence of any grave goods is unknown. It is presumed to be the tomb of the chief who ruled the Nei district, along with the Teshizuka tumulus, which is 400 meters south of the valley. 7. The (27,651 square meters) is a large conjoined-rectangle style tumulus dating from the 3rd century. It measures 66 meters in total length, with a posterior portion 31 meters x 24 meters with height of 3.5 meters and an anterior portion of 35 meters x 37 meters (narrowing to 11 meters in the waist) and a height of 9 meters, with a partial moat. It was found to contain a rectangular burial chamber measuring 6.2 meters by 6.1 meters containing the remnants of a wooden sarcophagus and a large number of grave goods. These included red-coated Haji ware pottery, as well as pottery from the Kinai region. It is presumed to be the tomb of the chief who ruled the Nei district, along with the Ōzuka Kofun, which is 400 meters north of the valley.
