Although I don't visit ANN on a regular basis, I was shocked to read that Gouri Daisuke (郷里 大輔) died.
According to ANN, the 57 years old actor was found 'with blood dripping from his wrist' by a passerby on a street in Nakano Ward.
Yomiuri Shimbun states that a knife and his last will were found nearby - probably due this, the police is investigating his death as a possible suicide.
Gouri Daisuke was a well known voice actor - he voiced Mr. Satan (Dragon Ball franchise), Dozle Zabi and Bask Om (Gundam franchise) and alot of other characters.
May he Rest in Peace.
