Chihiro Suzuki is a Japanese voice actor born on February 17, 1977, in Yamagata Prefecture. He made his debut in 1998 with the lead role of Soichiro Arima in the television anime His and Her Circumstances, a production directed by Hideaki Anno. His path to becoming a voice actor was initially met with family opposition due to its instability, but he pursued his goal by training at the Yoyogi Animation School and the Japan Narration Acting Institute. Over his career, he has been affiliated with I'm Enterprise and ARTSVISION, and has worked as a freelance voice actor since February 2010.

Suzuki is known for his versatile vocal range, adeptly portraying characters from earnest young men to immature protagonists and reticent villains. A landmark performance that showcased this skill was his dual role in the 2005 video game and subsequent anime Tales of the Abyss, where he voiced both the protagonist, Luke fon Fabre, and his rival, Asch the Bloody. This ability to distinctly portray two contrasting characters within the same work garnered significant attention and praise. Other prominent anime roles include Shun Kazami in the Bakugan Battle Brawlers series, Kisumi Shigino in Free! -Dive to the Future-, Kuma in Idol Time PriPara, Yūto Sakaeguchi in Big Windup!, Akira Kamio in The Prince of Tennis, and Noboru Terao in the acclaimed OVA Voices of a Distant Star. He also has an extensive history with the Di Gi Charat franchise, voicing the character Ky Schweitzer across numerous installments from the early 2000s through the 2022 series Reiwa no Di Gi Charat.

Throughout his career, Suzuki has been involved in several notable collaborations. He formed the musical unit P·K·O with fellow voice actors Kosuke Toriumi and Tomo Saeki, a group that originated from their work together on Di Gi Charat and released multiple music albums and held concerts. He has also maintained a long-standing working relationship with Toriumi. In addition to animation, his work extends to video games, drama CDs, and tokusatsu, such as his role as the antagonist Grand Beast Rei in the 2006 Super Sentai series GoGo Sentai Boukenger. His versatility is further underscored by his personal qualifications, which include a second-degree rank in Shorinji Kempo and proficiency in tarot card reading.
