the Guinness Book of World Records as the world's youngest professional guitar player

Miyazawa first performed with Osbourne and the rest of Ozzy's current group — guitarist Gus G. (FIREWIND), drummer Tommy Clufetos (ROB ZOMBIE, ALICE COOPER, TED NUGENT), bassist Rob "Blasko" Nicholson (bass; ROB ZOMBIE) and Adam Wakeman (keyboards) — on August 22, 2009 at the closing concert of last year's BlizzCon at the Anaheim Convention Center in Anaheim, California.
Born February 21, 2000 in Tokyo, Japan, Yuto Miyazawa has been playing guitar since the ripe age of three. Although he has had a few guitar lessons, the bulk of his expertise comes from truly wanting to play… all the time. Generally, if he is not in school, he has a guitar in his hands. That love of guitar is quickly making Yuto the Internet's latest addiction, as his videos rack up views on YouTube and Vimeo, and his name is scattered across hundreds of forums and blogs.
Yuto's influences are fairly apparent, as he usually seen playing his custom Randy Rhoads-style, polka dot flying V guitar, which dwarfs him. Along with Ozzy Osbourne and Randy Rhoads, Yuto is influenced by Eric Clapton, KISS and METALLICA.
After playing multiple variety shows in Japan, Yuto made his first trip to the States in May 2008 when he played with a few big names at various clubs in Manhattan. In his short stint in the U.S. Yuto was a hot commodity. He played with Les Paul at The Iridium, two nights later he hopped onstage with GE Smith and Moonalice at Rebel, and finally he headed over to B.B King Blues Club & Grill to play with GALACTIC.
Miyazawa performed "Crazy Train" on the May 11, 2009 episode of "The Ellen DeGeneres Show". Yuto was then surprised when Ozzy himself was brought out to meet the boy.
Yuto is now recognized by the Guinness Book of World Records as the world's youngest professional guitar player.
