Biography

Early life and education

Yamaguchi was born in Fukuoka. He graduated from Fukuoka's prefectural Chikuzen High School. In 1984, Yamaguchi moved to Tokyo and entered the Tokyo Announce University College, a vocational school training various performers from voice actors to singers to announcers or even reporters and dancers.Template:Cn

Background

Yamaguchi is the son of a carpenter father. He had been into anime as a child, but his interest lapsed in high school after joining a band.

He attended acting classes taught by Kaneta Kimotsuki, and soon joined his 21st Century Fox theater company. About a year after joining, he took the stage for the first time in a supporting role, and played the lead role of the boy detective in So Kitamura's "Odoriko ~THE DANCER MURDER CASE~". Template:Citation needed

Yamaguchi began working as a voice actor, voicing Ranma Saotome in Ranma ½.

Activities as a voice actor

He has appeared in numerous works in the fields of live-action dramas, animation, games, and foreign film dubbing. In anime, he specializes in playing lively children and young people. In the early 1990s, he also played low-key roles such as Eto in Record of Lodoss War and Gokujurota in Gale! Iron League.

In Case Closed, he plays Shinichi Kudo and Kaito Kid. His favorite "Conan" episode is "Flying Locked Room Shinichi Kudo's First Incident".Template:Citation needed

In One Piece, he originally wanted to play the role of Monkey D. Luffy, the main character, and went to audition, but was unsuccessful. He decided to play the role of Usopp after receiving an offer. Yamaguchi has been reading the original manga since the beginning of the serialization, and couldn't imagine what kind of voice the character would have prior to getting the role.Template:Citation needed
