Real name: Nakahama Yoshiyuki 中浜慶幸

Ruiza is a Japanese guitarist, most known for being one of the founding members of the metal-rock band D (18).
Born February 18th 1979 in Itami, he started working in the music industry since the mid 90's as a talent of the idol agency Johnny's Jr., playing such minor roles as background dancer for the boyband SMAP.
After quitting Johnny's Jr. in 1997, Ruiza adopted his current stage name and started playing guitar in visual kei bands attached to the Matina label such as Distray, Laybial, and the more popular band Syndrome (12).
After Syndrome disbanded in late 2002, he formed D (18) with vocalist and former bandmate Asagi.
Since his Syndrome days he has been occasionally active as a solo artist.
