[1] Kiyoharu's musical career began in 1986 as a member of the independent band Double Bed, which folded after a few months of activity.
However, Kiyoharu made mistakes in the budgeting for its elaborate stage production, and ended up incurring a debt of 50 million yen.
His debut album, Poetry, was released in 2004, showcasing not only his vocal skills, but his talent as a guitarist as well.
He has collaborated with many artists, including Hyde (L'Arc-en-Ciel), Takanori Nishikawa, Kirito (Pierrot), Atsushi Sakurai (Buck-Tick), Gara (Merry), Sugizo (Luna Sea) etc.
[3] In September 2016, four trademark rights related to Kuroyume were auctioned off by the Tokyo Regional Taxation Bureau due to Kiyoharu's Full Face Records' debt and failure to pay taxes.
Kiyoharu's manager said the singer wanted to buy the rights back from the unknown winner.
