From Bulbapedia, the community-driven Pokémon encyclopedia.
TAJ Productions is an American company involved in the dubbing and recording of voices for the Pokémon anime. Its current president is Larry Juris.
TAJ was the original dubbing company to work with 4Kids Entertainment on the anime back in 1997. They recorded at several different locations until around 2004,when 4Kids built their own audio base.
TAJ once again gained responsiblity for the dubbing in 2006, after 4Kids gave up their license for dubbing and distribution. Pokémon USA decided to use TAJ Productions as the recording studio for the dub.
On January 2, 2008 is was revealed by Larry Juris (TAJ President) that TAJ Productions will no longer be working on the show and Pokémon USA hired a new company to work on the show. A couple days later Sarah Natochenny herself confirmed this.
