Yuji Mitsuya is a highly respected Japanese voice actor, sound director, and actor with a career spanning from the late 1960s to the present day. Born on October 18, 1954, in Aichi Prefecture, he is a graduate of Meiji University. He began his entertainment career at a young age, gaining experience in theater, which led to an interest in voice acting. His debut in a major anime role came as Hyoma Aoi in the 1976 series Chōdenji Robo Combattler V, a part he secured following advice from veteran voice actor Ichiro Nagai.

Mitsuya is renowned for his clear, versatile voice, which has allowed him to portray a wide spectrum of characters. He is particularly celebrated for his performance as Tatsuya Uesugi in the beloved 1980s series Touch, a role that made him a household name in Japan and cemented his status as a leading voice actor of his generation. Another iconic and long-running role is that of the Gold Saint Virgo Shaka in the Saint Seiya franchise, a character he has voiced for decades, including in the original series and subsequent installments like Soul of Gold. His other prominent anime roles include the eccentric Dr. Tofu Ono in Ranma ½, the sinister Joker in Smile PreCure! (Glitter Force), the gluttonous Grinpatch in Toriko, the mischievous Souichi in Junji Ito Maniac: Japanese Tales of the Macabre, and the chaotic Popuko in one half of the surreal Pop Team Epic. He has also been a staple in the long-running children's franchise Soreike! Anpanman, providing the voice of Katsudonman for many years and across numerous films.

Beyond anime, Mitsuya is extraordinarily prolific in the field of Japanese dubbing (fukikae) for foreign films and television. He is the official Japanese dub voice for actor Michael J. Fox, most famously for the character Marty McFly in the Back to the Future trilogy in the TV Asashi editions. His voice is also synonymous with several beloved Disney characters: he voices the frantic alien Pleakley in the Lilo & Stitch franchise, the meerkat Timon in The Lion King and its sequels, and Rex the toy dinosaur in the Toy Story series, reprising these roles in various spin-offs and video games like Kingdom Hearts. His other notable dubbing credits include the roles of Wolfgang Amadeus Mozart in Amadeus and Jar Jar Binks in Star Wars: The Clone Wars.

In addition to his on-screen voice work, Mitsuya has made significant contributions behind the scenes as a sound director and voice director. He has supervised the audio for numerous series, including the long-running Yu-Gi-Oh! franchise, the film 5 Centimeters Per Second, and the musical adaptation of The Prince of Tennis, for which he also served as scriptwriter. He was also a keyboardist and vocalist for Slapstick, a band formed in the 1970s with fellow prominent voice actors Tōru Furuya and Toshio Furukawa, among others. In recognition of his long and varied career, he received the Kei Tomiyama Award at the 7th Seiyu Awards in 2013. He is the founder and representative director of his own agency, Mitsuya Project.
