Music career

  • He has his own band, Mosquito Milk, that performed the themes "Monkey" and "Mizu no Naka" as the opening and ending themes to the original Japanese version of Rockman X5.
  • He is a member of the popular seiyuu unit, An's All Stars (with Hideo Ishikawa), playing guitar and doing vocals as a duet in songs with Ishikawa. This band has had its own albums, singles, anime themes, and radio shows. Their latest songs are "Omomuku Mama ni..." and "You are my sky, You are my ocean...", featured in the Last Escort - Shinya no Kokucho Monogatari drama CD.
  • He is also a composer, and has written such songs as "I.D.E.A. ~Boku wa Mainichi, Yume o Miru~" (performed by RoST) for Rockman X6, and "Oh! Enka!" (performed by Junko Takeuchi) for Naruto.
  • He produced and wrote the lyrics for his songs from his solo album almost entirely himself, and he also wrote the lyrics and music to, and sang, a track from the movie Cross Chord.
  • He put together entirely, and sang, the two vocal songs, "Kiri no Mukō de" and "Mezametara...", for the soundtrack to the anime Ururun.

Career in anime

  • He has worked alongside Takahiro Sakurai in several anime.
  • He has voiced at least 2 roles whereby his character is associated with lightning. One is Thor in Matantei Loki Ragnarok; another is Amano Ginji in Get Backers and Kagami Kyoji in GB.
  • He has also worked alongside Kentaro Ito in at least two productions whereby their characters are linked. On top of that, both seiyu hailed from the same city and were of the same age, with less than two months' difference between their birthdays.
    • In the Hana-Kimi drama CDs, their characters are roommates and close friends. (Shotaro voices Shuichi Nakatsu, and Kentaro voices Taiki Kayashima.)
    • In Naruto, their characters are members of the same team. Also, Shikamaru (Showtaro) frequently expresses his confidence in Choji (Kentaro). Another coincidence is that in Hana-Kimi, Shotaro voices the glutton out of the pair; in Naruto, that role is reversed, as Chōji is the one who eats a lot.
    • He succeeded Kentaro Ito as the voice actor of Mega Man X from Mega Man X5 up to Mega Man X7.
  • He is the producer for the anime Oni-girl.
  • He once pursued becoming a professional athlete with tennis, but an injury led him to coaching instead. His hobby of tennis caused him to aim for a role in The Prince of Tennis (Which he now voices Akaya Kirihara). Shortly afterward, he started his seiyū career through Sigma Seven for a short while until opting to work unrepresented by a third party. (He now works under the VIMS agency.)
  • His seiyū career kicked off around 1996.


  • He grew up mostly with his father and has a younger sister, currently entering her teen years, whom he respects much.
  • Some of his most memorable childhood moments are of the times he spent with his cousins during the summer, and when he'd go skiing with his father.
