Yūichi Nagashima (born December 15, 1957 in Saitama) is a seiyū who works for Haikyo and is formerly affiliated with Production Baobab. His real name is Shigeru Nagashima. He has become synonymous with the character Chō that he played from 1984-1991 in the NHK children's show Tanken Boku no Machi, so in August 2006 he changed his stage name to Chō.
He is well known as the voice of Jaken in InuYasha. Other anime roles include Karuas in Slayers NEXT, Raon in Zoids: New Century Zero, Kawakubo in Steam Detectives, and Captain Hunks in Pumpkin Sissors.
