Katsuta is perhaps best known as the voice of Dr. Ochanomizu in the Astro Boy anime series.
The Asahi Shinbun newspaper reported on Saturday that voice actor Hisashi Katsuta passed away on Friday of senility.
Katsuta, along with Mari Shimizu and Yoko Mizugaki, received the Synergy Award at the 3rd Annual Seiyū Awards in 2009.
He reprised the role in the 1980 and 2003 versions of the anime, as well as in the Astro Boy: Hero of Space and Astro Boy: Shinsen-gumi films and Tezuka Osamu ga Kieta?!
