Hitoshi Doi's excellent seiyuu database enabled me to start the first edition of this works list; the current version owes much to the Animedia Data Book and various Japanese fan pages.
The Complete Takehito Koyasu
With illustrations, listed in alphabetical order. Very slow-loading.
The Chronological Takehito Koyasu
A variation of the above, without illustrations and listed in order of anime release date.
The Domestic Takehito Koyasu
Titles available commercially in the U.S.
The Rest of Takehito Koyasu
Game and CD drama titles. So I ran out of clever titles, so sue me.
The Musical Takehito Koyasu
Stuff he sings.
