Toshihiko Seki (関 俊彦 Seki Toshihiko?, born June 11, 1962) is a popular veteran Japanese voice actor (seiyū) who was born in Tochigi. His bloodtype is A and he is a member of 81 Produce; apart from seiyū work, Seki sometimes does live action drama stage work. He is sometimes mistaken for another seiyu, Tomokazu Seki, sharing the same last name but are unrelated.


According to the Anime News Network as of early August 2007, Seki Toshihiko is one of the more prolific [1] male seiyū with 215 roles credited to his name. He is tied with seiyu Tomomichi Nishimura and Nobuo Tobita.

In June 2004, Toshihiko was honored by the readers of Animage Magazine in the 26th Annual Reader's Poll, where he was ranked the 9th favorite seiyū currently working in Japan, largely in recognition of his performance as Rau Le Creuset from Mobile Suit Gundam SEED.[2]

Toshihiko tends to mostly voice characters who are very serious or easily agitated, e.g. Ougi Takaya in Mirage of Blaze, Sanzo in Saiyuki, Duo Maxwell in Gundam Wing, Iruka Umino in Naruto, Kaien Shiba in Bleach and Momotaros in Kamen Rider Den-O. However, he has also played those who are composed and pleasant (Luva, Ru Baraba Dom). On some occasions, he has also played charming sociopaths:(Legato, Rau Le Creuset).


  • Toshihiko has worked alongside Soichiro Hoshi a few times whereby their characters have strong interactions: In Gundam SEED, Kira Yamato (Hoshi) was the one who killed Rau le Creuset (Seki), who had long regarded Kira as a main threat; in Saiyuki, Goku (Hoshi) was rescued by Sanzo (Seki), who often abuses him with a paper fan as well; in the drama CD version of D.N Angel, Soichiro voices Niwa Daisuke while Toshihiko voices his father, Kosuke. In Higurashi no Naku Koro Ni, Hoshi's character Keiichi Maebara confesses to a murder to the town doctor, Irie (Seki). In Dissidia -Final Fantasy- Warrior of Light (Seki) is one of the warriors of the goddess Cosmos, along with Butz Klauser (Hoshi), but their interactions are minimal.
  • Also, he has voiced characters alongside Ai Orikasa whereby they were close friends.
    • In Gundam Wing, with Toshihiko as Duo and Ai as Quatre.
    • In the Kami-kaze drama CDs, the two voiced a couple (with Toshihiko as Higa and Ai as Kaede).
