Nobuyo Oyama, the Japanese Voice of Doraemon, Dies at 90

Nobuyo Oyama, the voice actress whose alto timbre and radiant laughter shaped how millions in Japan experienced Doraemon, the blue cartoon robot in the quintessential children’s anime of the same name, died at a hospital in Tokyo on Sept. 29. She was 90.

Her death was confirmed by phone on Friday by Yozo Morita, the chief executive of her agency, Actors 7, who said that she had suffered a stroke in 2008 and been living with dementia for years.

For about 25 years, Ms. Oyama was the voice of Doraemon, a character that first appeared in a manga created in 1969. Doraemon is a robot from the future, sent by its owner to the present day to help his great-great-grandfather solve his childhood problems and change his family’s fortunes.

The plump, earless, catlike robot typically helped the boy, Nobita Nobi, using gadgets from the future that he kept in his magical pocket. His deepening friendship with Nobita and his family was part of what made “Doraemon” one of the longest-running shows in Japan and beyond.

Ms. Oyama found her talent while coping with being bullied for her voice as a child, she told Kakugo TV, an online interview series. She was often told by her classmates that she had a “boy’s voice,” she said. The students, laughing whenever she spoke, discouraged her from speaking in public.

When her mother saw her withdrawing socially, she gave her a piece of advice that would shape her career: She should not hide her voice but find a way to use it. So she joined a broadcasting club in high school, where she hosted radio shows and performed in radio dramas.
