Mounded tomb (tumulus) of the Kofun period which is about 18 m in diameter and 5 m high, dating to the 7th century AD in Nara Prefecture, Japan. Excavation revealed paintings of human and mythological figures and celestial bodies, and murals of Chinese directional symbols, on the walls and the ceiling of the burial chamber. Close similarities to the Tang are seen and a Tang mirror and some gold- and silver-plated ornaments have been found.
