Ō no Yasumaro

was a Japanese nobleman, bureaucrat, and chronicler. He may have been the son of Ō no Honji, a participant in the Jinshin War of 672.

He is most famous for compiling and editing, with the assistance of Hieda no Are, the Kojiki, the oldest extant Japanese history. Empress Genmei (r. 707-721) charged Yasumaro with the duty of writing the Kojiki in 711 using the differing clan chronicles and native myths. It was finished the following year and presented to Empress Genmei in 3 volumes in 712.

Tomb of Ō no Yasumaro The tombstone and pearls that were found in the grave of Ō no Yasumaro. In 1980, it was designated as an National Cultural Artifact by the government of Japan. The tombstone is made of bronze. It is exhibited at the Museum attached to the Archaeological Institute of Kashihara, Nara Prefecture.

The tomb of Otomo no Yasumaro is located in the Konose-cho neighborhood of the city of Nara. It is located on the southern slope of a hill that stretches from east-to-west, near the northwestern end of the Yamato Plateau, which runs east of the Nara Basin. In 1979, a copper plate gravestone was discovered in a tea plantation. The tomb was excavated, and in 1980, it was designated a National Historic Site. The tomb was built on the top of a small ridge on a steep slope of about 30 degrees. The soil was all removed during land reclamation, but part of an arc-shaped ditch that surrounded the mound at the boundary between the tomb and the ridge remains, and if the mound is restored from this, the inner diameter of 4.5 meters. The grave pit is located almost in the center of the mound, and is slightly deformed, measuring 1.9 meters east-to-west and 1.8 meters north-to-south, and is dug almost vertically. A wooden coffin covered in charcoal was buried with its long axis running north-south in the north-north center of the burial pit, and judging from the hollow area remaining in the charcoal layer, the size of the coffin is estimated to be approximately 66-cm long, 3-cm wide, and 38-cm high. The grave-marker was placed under the wooden coffin, face down, with the top of the inscription facing north; it is made of a copper plate measuring 29.1-cm long, 6.1-cm wide, and 0.1-cm thick, and has writing on only one side. The inscription is written in two lines, with boundaries around it and in the center, and contains 41 kanji characters. Its engraving reads:

Grave goods found in the coffin included four pearls, two pieces of iron, and two pieces of plaster, along with cremated human bones and ashes.

In fiction Yasumaro appears in the video game Toukiden: The Age of Demons as a mitama (a soul of a hero from Japanese history).
