Yune Sugihara (Shan Yuan  You Yin , Sugihara Yune), born Yasuhiro Sugihara (Shan Yuan  Kang Hong , Sugihara Yasuhiro, on July 8, 1969 in Hadano, Kanagawa, Japan), known exclusively by his stage name Sugizo, is a Japanese musician, singer, songwriter, composer, and record producer. He is best known as lead guitarist and violinist of the rock band Luna Sea.

After Luna Sea went on break in 1997, Sugizo started his own solo career and opened the independent label "Cross" to produce other artists, as well as releasing his own records. He points out that the opening of his record label was one of his very important projects at the time, but not anymore. On July 9, his debut single "Lucifer" was released and reached number 8 on the Oricon singles chart. It was followed by his first solo tour "Abstract Day" which lasted until the final performance in August at Akasaka Blitz, where he was joined by DJ Krush, Masami Tsuchiya and members of Japan. Then on September 10 he released his second single, "A Prayer", which reached number 7 on the charts. On November 19, his first solo album Truth? was released, and reached number 12 on the album charts. It was met with mixed reviews, largely because of the unexpected musical style which mixed different genres with electronica beats. A variety of artists participated in the album, from Ryuichi Sakamoto and Mick Karn, to Lou Rhodes and Valerie Etienne. Towards the end of the year, remix editions of his two maxi singles and album were released.  As Luna Sea resumed activities, until the bands disbandement, Sugizo collaborated in the studio with actress Miki Nakatani, and singers Miu Sakamoto and Vivian Hsu among others. On August 11, 1999 a compilation album titled "Grand Cross 1999", which was sponsored by Sugizo's record label "Cross", was released, featuring many musicians with whom he had worked with before and many for the first time.  In 2001, he participated in Ryuichi Sakamoto's N.M.L. ("No More Landmines"), a campaign to promote awareness of the problems of land mines and promote a ban on them, and helped in the making of the album Zero Landmine. He starred in Ken Nikai's movie Soundtrack and composed the music for the film. On November 14, a compilation album inspired by the film, titled Parallel Side of Soundtrack was released, and the following year he released the single "Rest in Peace & Fly Away" featuring Bice on vocals. That same year he produced the music for, as well danced in, Suichoku no Yume, a production by the popular contemporary dance company H. Art Chaos.
