Early life and first activities in Ehime

Kaya was born in Tokushima (Shikoku). He has two older sisters and a younger brother. He claimed to have been aiming to become a singer since he sang at a local karaoke feast at the age of 3. Although no information were given about his vocal training, he confirmed to have been taking piano lessons since he was 14 and writing lyrics since he attended high school. His first band was a ROUAGE cover band called ZephyrZone in 1997.
In 1998 Kaya joined the Ehime-based visual rock band Meties and at the same time worked for the indies label LAST CHILD. His stage name at that time was (Hime, japanese for princess). Meties were active in the late 90's and released several demo tapes before disbanding in 1999.

Band activity in Tokyo (2002 - 2006)


Kaya in ISOLA, 2000 circa

After graduating high school Kaya moved to Tokyo and joined another visual rock band: ISOLA. Despite being active in the visual kei scene, Kaya seemed to enjoy more clubbing and such music genres as dance, pop, hardcore and techno.

While he was still a member of ISOLA, Kaya attended a VELVET EDEN concert and kept in touch with the band keyboardist Hora since then. Sharing the same musical vision, they soon decided to leave their former bands and create a new project together which they named Rudolf Steiner. Their aim was to convey an image of digital decadence, without using acoustic instruments at all. During a concert in 2002 Rudolf Steiner were spotted by ex MALICE MIZER guitarist Mana, who was gathering some bands to do some live events. Shortly after that he offered them a contract with his own label Midi:Nette and became their sound producer.

Kaya in 2004

Rudolf Steiner changed their name to Schwarz Stein to commemorate the label change, and at the same time Kaya adopted his current change name.
Over a span of two years Schwarz Stein released two full albums, several singles and became quite popular in the indies scene, opening for Moi dix Mois several times but also holding quite successful oneman concerts. Their second single Current ranked #6 at the ORICON indies chart in November 2003 and in March 2004 the second album Artificial Hallucination managed to rank #16. However, the musical differences between the two members led to their disbandment in March 2004, followed by a one-night revival on December 15th 2004.
For the following two years Kaya disappeared from the music scene, though he was told to have performed in unknown session bands. His official comeback to the music scene took place in early 2006 with the session unit another cell, a one-release only collaboration with his ex-bandmate Hora. This project helped Kaya to launch his own solo career.
