One of the newer seiyuus of the 2010s, Yūki Kaji (born September 3, 1985) burst into the seiyuu industry as Final Fantasy XIII's vengeance-driven Adorably Precocious Child Hope Estheim. He has since voiced a number of prominent male characters (leading to many jokes by his fans and fellow seiyuu about his "main character syndrome"). Infamously was once regarded as a source of X-Pac Heat with a reputation for Wangst due to playing quite a few Scrappies and Base Breaking Characters early in his career, but a series of He Really Can Act roles have since established him as a respectable actor. Kaji sports a very wide vocal range, going all the way from Child-Like Voice to Badass Baritone when need be.
Has also worked with Yūichi Nakamura, Marina Inoue, Mamoru Miyano, Hiro Shimono, Kana Hanazawa, Hiroshi Kamiya, Natsuki Hanae, Takahiro Sakurai, Yui Ogura, Daisuke Ono, Kensho Ono, Daiki Yamashita, Yoshimasa Hosoya, Ayumi Fujimura, Maaya Sakamoto, Yu Shimamura, Sora Amamiya, Yōko Hikasa, Ai Kayano, Romi Park, Kaito Ishikawa, Nobuhiko Okamoto, Rina Sato, Jun Fukuyama, Kōki Uchiyama, Junichi Suwabe, Katsuyuki Konishi, Kenta Miyake, Hiroki Yasumoto, Tomokazu Sugita and Aoi Yūki in a few roles. Also has admitted that he thinks of Nakamura as a Big Brother Mentor in the latter's show, Tokyo Encounter.
He's also a two-time winner for Best Lead Actor in the 7th and 8th Annual Seiyuu Award.
He also authored a book that tells his life of how he became a seiyuu called "Itsuka Subete ga Kimi no Chikara ni Naru" and has a manga adaptation of the series.
On June 23, 2019, he announced that he married fellow seiyuu, Ayana Taketatsu.
He opened up a Youtube channel in 2020, where it initially featured classic stories narrated by him and Animal Crossing playthroughs. It has since expanded to include playthroughs of other popular games, videos with fellow seiyuu, actors, and even some of his non-celebrity friends, promotions about his other projects, and many more.

Tropes Associated with Yuki Kaji:
- Casting Gag: It's become something a
meme lately that he manages to somehow get casted as the lead character of an anime, such as Eren, Meliodas, Kou, Takeru, Eight, etc. (Even Koichi, who isn't the main character, but the story is told from his perspective) His fellow seiyuu colleagues have picked up on this and have hilariously dubbed this phenomenon as "Main Character Syndrome"
.
- Man of a Thousand Voices: His main forte. He can easily slip from a cute, high-pitched voice all the way down to a Badass Baritone and everything in-between for many of his roles. His 2021 voice sample
gives a pretty idea of what he's capable of now (he even voices an old man!).
- Promoted Fanboy: His two biggest dreams were to voice a character in Dragon Quest, and to voice a character in Super Smash Bros.. In Super Smash Bros. Ultimate, he got to kill two birds with one stone, being cast as the role of Eight.
- Vocal Evolution: It's fairly subtle since his main timbre of voice has barely changed, but his range has grown significantly from his debut days. Just compare his 2007 voice sample
(a mere 1 minute and 41 seconds long) to the above 2021 voice sample (4 minutes and 12 seconds; a 3 minute, 29 seconds difference).
