Medama-Oyaji has been performed in all five anime series by Isamu Tanonaka, as well as in most other media.

The only instance where Tanonaka did not perform the role in his lifetime was for the video game series, in which veteran voice actor Kazuo Kumakura took the role (who is also known for singing the original version of the Kitarō theme song). Also, in episode 4 of the 1971 anime, Tanonaka was out sick and frequent guest star Hiroshi Ohtake filled in. However, the end credits still listed Tanonaka for the role and instead credited Ohtake as a guest star.

Following Tanonaka's death in 2010, Nurarihyon's regular voice actor Takeshi Aono took the role of Medama Oyaji for the TV Special Kitarō: The Happy Journey.
