Gakuto Oshiro, better known by his mononymous stage name Gackt, is a Japanese singer-songwriter, musician, record producer and actor.
Born in Okinawa, Japan, to a Ryukyuan family, Gackt learned the piano at a young age and was raised on classical music and enka before becoming interested in rock music while attending high school. He has been active since 1993, first as the frontman of the short-lived independent band Cains:Feel, and then from 1995 the now-defunct visual kei rock band Malice Mizer. Gackt started his solo career in 1999 with debut mini-album Mizérable and first full-length album Mars. He has released nine studio albums and, with forty-eight singles released, holds the male soloist record for most top ten consecutive singles in Japanese music history. They are mostly conceived around two conceptual stories "Moon Saga" and "Requiem et Reminiscence" which are performed live in uniquely elaborate concerts. His single "Returner", is his first and only single to reach the number one spot on the Oricon charts. As a solo artist, Gackt has sold over 10 million records. In 2007 became a founding member of S.K.I.N., a Japanese visual kei rock supergroup.
