Nobuyo Ōyama

Nobuyo Ōyama (大山 のぶ代), born Nobuyo Yamashita (山下 羨代), is a former Japanese actress and singer affiliated with Actors Seven. She is best known for playing the title character in the Doraemon anime series that ran from 1979 to 2005. She is also well known as the voice of Monokuma, the main villain from the Danganronpa video-game series. She played him in the first three video games and in Danganronpa: The Animation.

It was reported on May 13, 2015 that Ōyama was living with dementia, putting any future work on hold. This notably prevented her from voicing Monokuma in future Danganronpa projects, and in April 2016, it was revealed that Tarako had taken over the role.
