Sasuke Haraguchi

Sasuke Haraguchi (Japanese: 原口沙輔, Hepburn: Haraguchi Sasuke; born May 21, 2003) is a Japanese music producer, composer and Vocaloid musician best known for his 2023 song "Hito Mania". He began producing music digitally from a young age, and was noticed by the internet at age fourteen when a recording of him playing the Akai MPC on the streets of Harajuku went viral online. In 2018, he signed a deal with Warner Music Japan and would release J-pop singles under the alias Sasuke until his departure from the label in 2021.

In 2023, he rebranded to his full name, and began to produce electronic Vocaloid songs influenced by hyperpop, gaining popularity after submitting his work to the semi-annual event The Vocaloid Collection. Since then, he has produced music for several media properties and released three studio albums, "Acetone" (2023), "Screen II" (2023), and "Isan" (2026).
