He was born in 3 Zhekhsogon nasleg of Boturuss (nowadays Tatta) ulus. The etymology of the family name "Sleptsov" is that it came from the word meaning "a shaman" – such is the source of Oyunsky's pen-name.^[1]

He took part in creating the national written language and in culturally building the modern Yakut nation. Oyunsky is one of organizers of the Yakut Autonomous Republic, the Union of Writers of Yakutia, and the Language and Literature Scientific Research Institute.

Oyunsky collected and published a number of Olonkho epic poems from the collected heroic epic poetry of the Yakuts.

He was prosecuted during the Great Purge, and died in prison in Yakutsk in 1939.^[2] Oyunsky was officially rehabilitated on 15 October 1955.
