Anime Dictionary:Seiyuu

Seiyuu is the Japanese term for voice actor or actress - whether in animation, radio, dubbed non-Japanese films, etc. In Japan, seiyuu are often less anonymous as artists than voice actors in the West. Many of the most famous seiyuu (e.g. Tsumugi Kotobuki) have large fan groups of their own.
