Miyavi was born in the Nishikujo district in Konohana-ku ward, Osaka, Osaka Prefecture, to a Korean Japanese father and a Japanese mother. After the first grade, he moved to Kawanishi. His father's family, surnamed Lee, came from Jeju Island. Miyavi says that as a child he was a good student and enjoyed playing football.

In 2004, he starred as himself in the film Oresama. In February he went on his first solo tour, Tokyo Dassou, and in July additional dates were added in Korea and Taiwan. In June his seventh single, "Ashita, Genki Ni Naare", was released, which charted twenty-second, and number one on the indies chart. In August a small, free, fan-club-only event was organized in Tokyo Dome, and on the 31st he held his last indie concert at the Nippon Budokan. In October, he signed a major contract with Universal Music Group, but was still co-managed by PS Company. This was followed by the release of his first major (double) single, "Rock no Gyakushuu/21sekikei Koushinkyoku", which entered the top ten on the charts.  During May 2005 another single, "Freedom Fighters -Icecream wo Motta Hadashi no Megami to, Kikanjuu wo Motta Hadaka no Ousama-", was released, which charted tenth, and on June 1, his first major album, Miyavizm, was released. It was his first album to enter the top ten in the charts. It was followed by the third major single, "Kekkon Shiki Uta/Are you ready to Rock?", which is his best charting single, along with "Dear My Friend"/"Itoshii Hito", released in 2006; both reached number six. In December he performed at the first Peace & Smile Carnival organized by PS Company.  In late 2005 and for most of 2006, Miyavi shifted to an acoustic/pop sound reflected in his second and third major albums, MYV Pops and Miyaviuta -Dokusou-, released on August 2 and September 13 respectively. They charted at fifteenth and twenty-fifth. The first album singles, "Senor Senora Senorita/Gigpig Boogie" and "Kimi ni Negai Wo", are not different in style. They charted as tenth and twenty-sixth respectively. Miyavi showcased his new acoustic style for the first time in the 25 Shunen Kinen Koen concert series held at Tokyo Geijutsu Gekijo for five days in September around his 25th birthday. Miyavi left for America for the next six months to study the English language and take dance classes, and, on the weekends, went to Venice Beach and gave street performances.  On February 17, Miyavi, having been invited by the break dancer Mr. Freeze, performed with the local DJ and percussionist at his first solo concert in the United States, at the Tabu Ultra Lounge in the MGM Grand, Las Vegas. On May 25, at the JRock Revolution concert organized by Yoshiki Hayashi at the Wiltern Theatre in Los Angeles, it was officially announced that Miyavi would be a member of a band named S.K.I.N.. On June 29, the band held their debut and their only concert yet at the anime expo in Long Beach, California.  In June, Miyavi's seventh major single (and 14th overall), "Sakihokoru Hana no you ni -Neo Visualizm-/Kabuki Danshi", was released in Japan, which charted as twelfth. In July, a remixed extended play, 7 Samurai Sessions -We're Kavki Boiz-, was released, which includes re-arrangements of his past songs. It charted as forty-fourth. It was followed by Miyavi's nationwide tour, which started on July 16. He also performed at Animagic in Bonn, Germany, and in Seoul, South Korea. In November his tenth major single was released, "Subarashikikana, Kono Sekai - What A Wonderful World", which charted as thirteenth.  On January 16, 2008, his ninth major single was released, "Hi no Hikari Sae Todokanai Kono Basho De", on which he collaborated with fellow Skin guitarist Sugizo. It is his third single to enter the top ten. On March 19, his fourth major studio album was released, titled, This Iz the Japanese Kabuki Rock, which charted as twenty-fifth. In May, it was followed by his very first worldwide tour, This Iz The Japanese Kabuki Rock Tour 2008, with 33 concerts in the United States, Chile, Brazil, Germany, England, the Netherlands, Spain, Sweden, Finland, France, Taiwan, South Korea, China and Japan. The tour covered a distance of approximately 48,385 miles, equivalent to almost two trips around the world, and the majority of the concerts were sold out and covered extensively by media organizations. It was the most successful international tour undertaken by a Japanese artist in history. On June 27, a compilation album, Azn Pride -This Iz the Japanese Kabuki Rock-, was released in Korea and Taiwan, later also in Japan, which charted as forty-fourth. In September he performed in Beijing, China. On December 24, a remix album was released, Room No. 382, which failed to enter the top hundred.  In 2009, on January 3, Miyavi performed at the 10th Anniversary Commemorative concert by PS Company at the Nippon Budokan. On April 5, Miyavi left the PS Company because their ten-year contract expired, and on April 8 launched his own company, J-Glam inc., of which he is the president. On April 22, a compilation album was released, Victory Road to the King of Neo Visual Rock, which includes all his major singles with Universal Group. On June 1, "Super Hero," a new song, was released through his official Myspace, and in September his International Fanclub was opened. On September 19, Miyavi started his second worldwide tour, Neo Tokyo Samurai Black 2009/2010, in Moscow, Russia. He held 17 concerts in Europe, visiting Austria, Hungary and Italy for the first time. The tour immediately continued in South America, with concerts in Brazil, Argentina, Chile and Mexico. The United States leg was canceled due to illness and an injury, but Miyavi managed to perform in November at Anime Matsuri, Texas. On December 31, he signed a new contract with EMI Music Japan.  On March 10, 2010, his first single with EMI was released, "Survive", via iTunes. The worldwide tour was continued on March 28, with the concert at Human Stage, Okinawa, and nationwide.
