Various news reports have reported that seiyuu Kinryuu Arimoto
died at dinner time on February 1 in an hospital in Tokyo, Japan. His cause of death was due to esophageal cancer. He was 78 years old. A funeral was already held among the family.
Arimoto is famous for voicing Newgate Edward from the One Piece
series. He also voiced Tomomi Masaoka from the Psycho-Pass
series and Eddie Jay from the Uchuu Kyoudai
series, to name a few. He also dubbed Christopher Walken's roles and was also active as a stage actor. His name actually reads as Yoshitaka, but the Kanji was deemed hard to read so he changed it to Kinryuu while active in the entertainment field.
