Anime voice actor Taro Arakawa passed away on November 15, 2012 at the age of 56 from multiple organ failure. Arakawa's credits include Norisuke Namino in Sazae-san, and his voice could also be heard in such anime as Dirty Pair, Mobile Suit Gundam ZZ, Princess Minky Momo, Doraemon, Crayon Shin-chan, Yu Yu Hakusho, and Detective Conan (aka Case Closed).

I have posted a biography of Taro Arakawa at the Anime sire.
