Description
Takezou Koike is a stage name used by the Japanese voice actor Hideki Ogihara, primarily for his work in adult-oriented video games and original video animations. Ogihara was born on November 29, 1972, in Tokyo, Japan. He began his voice acting career in the late 1990s and has been active since approximately the year 2000 under the Koike alias. His career has involved roles across a wide range of media, including visual novels, PC games, drama CDs, and anime.
The name Takezou Koike is specifically associated with roles in adult games, known as eroge, and related OVAs, allowing Ogihara to maintain a separate professional identity for mainstream projects. He has voiced numerous characters in this genre, often taking on lead or principal roles. A significant portion of his early work in the 2000s involved titles from studios like Navel and BaseSon. Notable performances credited to Koike include Itsuki Midoriba in the popular game Shuffle!, Takurou Hayami in the OVA series Discipline, and Kūya Hiiragi in the OVA series Nee, Chanto Shiyō yo! (姉、ちゃんとしようよっ!). Another role from this period is Natsuki (as Takurou Hayami) in the series Magical Kanan (DISCIPLINE).
Over his decades-long career, Koike has taken on roles in many well-known adult game franchises. He portrayed Takeshi Yagi in Izumo 2 and its sequel, Naoyuki Higashi in Ashita no Kimi to Au Tame ni, and Kazuma Morisato in Ore-tachi ni Tsubasa wa Nai. He also voiced Kyōichi Hanashima in Cross Days, a spin-off from the School Days series, and Shūji Ishida in Chrono Clock. His filmography under this alias extends into the 2020s, with a role as Shū Kokubunji in the 2022 game Chizome no Ori.
A key characteristic of Koike's career is his recurring involvement with specific creative teams and franchises. He has frequently collaborated with the software developer Navel, providing voices for characters in their Shuffle!, Really? Really!, and Soul Link series. He has also been a regular contributor to the works of ALcot and Minato Soft, appearing in their Triptych and Aoi Shiro series, among others. This pattern of returning to established series and working with consistent studios marks a significant portion of his voice acting portfolio under the Takezou Koike name.
