Gakuto Oshiro (大城 ガクト, Ōshiro Gakuto, born July 4, 1973), better known by his mononymous stage name Gackt, is a Japanese musician, singer, songwriter, 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 for the now-defunct visual kei rock band Malice Mizer, before starting his solo career in 1999. 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. His single "Returner (Yami no Shūen)", released on June 20, 2007, was 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.
