Isamu Tanonaka

Biography

was a Japanese voice actor from Taitō, Tokyo. He was best known for voicing Medama Oyaji in nearly every adaptation of Shigeru Mizuki's GeGeGe no Kitarō made during his lifetime. During his life he had been attached to Gekidan Tōgei and then Theatre Echo; he was attached to Aoni Production at the time of his death. He had a naturally deep voice but became famous for voicing characters with a high pitched voice.
