Takehiro Mamiya was born on September 25, 1989,[3] when his parents were expecting a baby girl. He first learned to play the guitar in the sixth grade, by his father.[4] First playing on piano and guitar in junior high school, he began to write music for club activities,[5] and later performed on guitar and vocals in a band since high school.[4]

In 2008, Yuyoyuppe began to post videos on the video sharing service Nico Nico Douga,[4] where he would become well known for his Vocaloid songs with elements of hard rock,[6] with considerable success for his song "Hope", sung by Hatsune Miku.[5] He would later join the band My Eggplant Died Yesterday as a vocalist.[7]

Yuyoyuppe has produced music for other artists, such as Babymetal, for their debut album Babymetal.[12] He has since written music for the band, including the song "Karate" from Metal Resistance. Finding appeal in the band's music, he was approached by the band's manager Kobametal to write a song, to which he obliged.[13]

Mamiya also performs as a DJ under the stage name DJ'Tekina//Something, having performed at the Rock in Japan Festival and Summer Sonic Festival.[14][15][16]

His music follows the genres of rock and metal.[17]
