There are at least 3 artists with the name "Hachi" : 1. Kenshi Yonezu (米津玄師 Yonezu Kenshi, born March 10, 1991), or better known for his producer name Hachi (ハチ) , is a Tokushima-born Vocaloid original song producer (composer and lyricist) and illustrator. He started producing VOCALOID original songs around May 2009. Before this, he had already been producing music. The songs which he composes have a unique point of view, which is common in his songs. Similar to his musical works, his illustration style is also very characteristic, using a scribbled style, often combining abstract, surrealist, and urban elements. On May 16, 2012, he released his third album, "diorama," moving away from VOCALOIDs by singing every song himself. He credited the album with his real name, Kenshi Yonezu, instead of his producer name, Hachi. He released three songs from the album on his Niconico account, to which they received much praise, despite not utilizing VOCALOIDs. On July 21, 2017, he returned to the VOCALOID world by making the theme (Suna no Wakusei) for Hatsune Miku Magical Mirai 2017. After this, he went back to being a solo artist. 2.
