## Identity and verification
Identity is confirmed across independent record types. The official 81 Produce profile lists the stage-registered name 榊原 優希 with the reading さかきはら ゆうき, a September 18 birthday, and Okayama Prefecture as his place of origin.[1](https://www.81produce.co.jp/dcms_plusdb/index.php/item?id=49) The Anime News Network encyclopedia records the same kanji for family and given names (榊原 優希), the same birthday, and the hometown as Ibara, Okayama, with a link to the 81 Produce entry.[7](https://www.animenewsnetwork.com/encyclopedia/people.php?id=199588) The Japanese biographical reference JINBUTSU and Newtype magazine's interview both match these data and confirm the 81 Produce affiliation.[2](https://jinbutsu.jp/catalog/people/sakakihara-yuki.html) • [3](https://note.com/newtype_magazine/n/nc070dc507cf9)
The agency gives only the prefecture, while JINBUTSU and ANN both specify Ibara City as his hometown.[1](https://www.81produce.co.jp/dcms_plusdb/index.php/item?id=49) • [2](https://jinbutsu.jp/catalog/people/sakakihara-yuki.html) • [7](https://www.animenewsnetwork.com/encyclopedia/people.php?id=199588) When fan-maintained databases conflict with official listings, the agency profile and production credits govern; in this case MyAnimeList's credits agree with ANN and the Japanese sources on the major roles.[6](https://myanimelist.net/people/388/Yuuki_Sakakihara)
## Early life and training
Sakakihara is from Ibara, Okayama Prefecture.[2](https://jinbutsu.jp/catalog/people/sakakihara-yuki.html)
In his Newtype awards interview he traced his origin as a performer to elementary school: his mother checked his reading-aloud homework rigorously, with director-like feedback.[5](https://webnewtype.com/report/cast/entry-30161.html) JINBUTSU adds that he became interested in voice acting partly by imitating characters from dubbed films and by narrating a film shown at his high school festival.[2](https://jinbutsu.jp/catalog/people/sakakihara-yuki.html) For training, he attended Amusement Media Academy at night while enrolled at university, and entered 81 Produce through a connection with the voice actor Kujira.[2](https://jinbutsu.jp/catalog/people/sakakihara-yuki.html)
## Career and debut
Sakakihara began voice acting in 2018.[2](https://jinbutsu.jp/catalog/people/sakakihara-yuki.html) The role he calls the turning point of his life, not merely his career, was Uta Kamijo in the idol training game *Readyyy!*, because it led to joining his agency. The work required him to memorize dance routines and full-length songs and to perform at events without a prompter.[4](https://note.com/newtype_magazine/n/nb2e7d158e242?hl=en)
In 2023 he played lead or lead-level characters in two series in the same season: Asahi Ikusaba in *Isekai One-Turn Kill Nee-san* (spring 2023) and Polka Shinoyama, the Corpse God, in *Dead Mount Death Play* (spring 2023, with the second part in fall 2023).[6](https://myanimelist.net/people/388/Yuuki_Sakakihara) • [2](https://jinbutsu.jp/catalog/people/sakakihara-yuki.html) He identified these two performances as the ones especially evaluated in his award win.[3](https://note.com/newtype_magazine/n/nc070dc507cf9) On March 9, 2024, the 18th Seiyu Awards, honoring the most active voice actors of 2023, announced its winners, and Sakakihara received the Newcomer Award.[5](https://webnewtype.com/report/cast/entry-30161.html)
## Notable roles
His voice type is a defined part of his casting. In the awards interview he described his voice as neutral and gender-ambiguous (中性的), suited to children, youths, and high-voiced male characters, and called that range his selling point.[5](https://webnewtype.com/report/cast/entry-30161.html)
**Anime.** Beyond his 2023 leads, ANN credits him as Yuu-kun in *The 100 Girlfriends Who Really, Really, Really, Really, Really Love You* (episodes 9, 14, and 28 across seasons), as Shu Ujigawa of εpsilonΦ in *Argonavis from BanG Dream!*, as Yako Amano in *Ayaka: A Story of Bonds and Wounds*, and as Noah in *Skill<>* (Bikkuri-Men).[7](https://www.animenewsnetwork.com/encyclopedia/people.php?id=199588) JINBUTSU lists Robota in *Lycoris Recoil* among the roles that built his record.[2](https://jinbutsu.jp/catalog/people/sakakihara-yuki.html) The agency profile lists Peter in *AYAKA-あやか-* and Helios in *「陛下わたしを忘れてください」*.[1](https://www.81produce.co.jp/dcms_plusdb/index.php/item?id=49)
**Games.** He has voiced Kyogoku Masamune in *Touken Ranbu ONLINE*[2](https://jinbutsu.jp/catalog/people/sakakihara-yuki.html) and the Japanese voice of "The Ring" in *Reverse: 1999*.[7](https://www.animenewsnetwork.com/encyclopedia/people.php?id=199588)
**Hypnosis Mic.** Since 2020 he has played Jushi Aimono of Bad Ass Temple in *Hypnosis Mic -Alternative Rap Battle-*, a character who lives by the word "futaiten," meaning not backing down.[4](https://note.com/newtype_magazine/n/nb2e7d158e242?hl=en) He continued in the role for *Hypnosis Mic -Division Rap Battle- Rhyme Anima +* (fall 2023) and the 2025 film.[6](https://myanimelist.net/people/388/Yuuki_Sakakihara)
## Other activities: radio and music
The 81 Produce profile lists him as a personality of the radio program 鵜澤正太郎と榊原優希の○欲男子栽培中！ (with Masataro Uzawa) and as an assistant on the Comic Seymour presents 伊東健人と選ぶ! 電子コミック大賞 program.[1](https://www.81produce.co.jp/dcms_plusdb/index.php/item?id=49) In music, ANN credits insert song performances as Bad Ass Temple in *Rhyme Anima PLUS* (episodes 3, 7, and 12-13) and theme song performances as Division All Stars.[7](https://www.animenewsnetwork.com/encyclopedia/people.php?id=199588) In the Newtype interview he stated a stance of challenging anything, including web radio, streaming, recitation dramas, stage work, and television appearances.[3](https://note.com/newtype_magazine/n/nc070dc507cf9)
## By the numbers
MyAnimeList counts roughly 38 distinct listed anime and music credits running from 2018 (*Readyyy!*, *Beat in Love*) through titles listed for fall 2026.[6](https://myanimelist.net/people/388/Yuuki_Sakakihara) Lead roles cluster in 2023, with four series credits as a main cast member that year (*Dead Mount Death Play* and its second part, *Isekai One Turn Kill Neesan*, and *Rhyme Anima +*).[6](https://myanimelist.net/people/388/Yuuki_Sakakihara)
## What has changed since 2023
After the award year, casting widened. 2024 roles include Tamao Akisame in *Youkai Gakkou no Sensei Hajimemashita!* (fall 2024), Latta in *Dungeon no Naka no Hito* (summer 2024), and Carbou and Gurenarma in a 2024 Poketoon short.[6](https://myanimelist.net/people/388/Yuuki_Sakakihara) For 2025, [MyAnimeList](https://www.edgepedia.org/myanimelist) lists Joel in *[Dr. Stone: Science Future](https://www.edgepedia.org/dr-stone-season-4)* (Parts 2-3), Neil Clay Maywood in *Silent Witch* (summer 2025), Twin Tail in *One Punch Man 3* (fall 2025), and the lead as Jushi Aimono in the *Hypnosis Mic* movie.[6](https://myanimelist.net/people/388/Yuuki_Sakakihara) For 2026 it lists Kirara Hoshi in *Jujutsu Kaisen: Shimetsu Kaiyuu - Zenpen* (winter 2026), Aiki Hirose in *Ganbare! Nakamura-kun!!* (spring 2026), and, in fall 2026, Fuyuki Hinata in the new *Keroro Gunsou* and Kyoutarou Otohara in *Tougen Anki*.[6](https://myanimelist.net/people/388/Yuuki_Sakakihara) JINBUTSU, a Japanese-language source, independently reports that he won the Kirara Hoshi role through an audition for the *Jujutsu Kaisen* adaptation broadcast in January 2026.[2](https://jinbutsu.jp/catalog/people/sakakihara-yuki.html) The 2025-2026 slate rests on the fan-maintained MyAnimeList database and should be read with that caveat.[6](https://myanimelist.net/people/388/Yuuki_Sakakihara)
