Yuki Sakakihara is a Japanese voice actor and singer born on September 18, 1995, in Ibara, Okayama Prefecture. He is affiliated with the talent agency 81 Produce. Sakakihara's interest in voice acting was sparked during his childhood by his mother's instruction on his reading assignments for school and was further inspired by his experience narrating a film for his high school's cultural festival. He pursued this passion by attending the Amusement Media Academy in the evenings while majoring in biology at a university during the day, graduating from the academy in 2017. After meeting with voice actress Kujira, a family connection of a college friend, he chose to join 81 Produce.

Sakakihara began his professional career in 2018 and has since portrayed a wide variety of characters, often utilizing his naturally high-pitched voice for roles ranging from young boys to teenagers and even effeminate men.
