Camellia (musician)

Masaya Oya (Japanese: 大箭将也, Hepburn: Ōya Masaya; born September 28, 1992), known professionally as Camellia (Japanese: かめりあ, Hepburn: Kameria), is a Japanese electronic musician and record producer. He is best known for his work in the rhythm game scene and has been a composer for games such as Sound Voltex, Hatsune Miku: Project Diva and Beatmania IIDX. Outside rhythm games, he has worked with the record label Pony Canyon and is a member of the label EXITTUNES Dance Production or EDP, an imprint of Exit Tunes. He also publishes his discography on his doujin circle, KamelCamellia.

Oya began his career with a Vocaloid sound. After leaving the scene in 2013, he primarily composed fast-paced electronic dance music (EDM) tracks, often reaching or exceeding 200 beats per minute (BPM). His music encompasses a variety of electronic styles, including J-core, dubstep, denpa, drum and bass, hardcore, gabber, trap, speedcore, and doujin music. Rather than adhering to a single genre, he is noted for actively experimenting with diverse sounds across his works.

He often collaborates with and has released several albums alongside the singer Nanahira. He has also produced remixes of the Undertale original soundtrack (OST) and collaborations with the game designer and composer Toby Fox. His track "Ghost" gained attention as one of the hardest songs in the VR rhythm game Beat Saber at the time of its release. He is popular outside of Japan through the video game osu!, where he has a dedicated fan community. Oya is also an active streamer on Twitch.
