HY formed in year 2000 with five high school friends in Okinawa. The band's popularity rose rapidly after a series of street performances; their debut album Departure (Okinawa-only) sold out immediately. In 2002, the band conducted a joint live performance with Linkin Park. Their second album Street Story released in April 2003 topped the charts, staying at #1 for four straight weeks (Indies Artist Record). Their third album Trunk was released the following year and yet again debuted at #1 — the first time such a feat has been accomplished by an Indies Artist. The band's latest album, Confidence, created yet another Indies Music Record by debuting at #1 and retaining the top spot for two consecutive weeks. HY has sold out all of their solo concerts. Their 2006 tour was a 47-location nationwide tour that sold out the day that the tickets became available. The tour gathered over 88,000 people. On December 2006, HY's Kumakara Amae ("from the present to the future") concert held in Nihon Budokan and Osaka-jou Hall sold out immediately and gathered over 20,000 fans in a mere two days. HY's recently entered the international music scene, starting with their first-ever overseas tour, beginning at Toronto, Canada and extending to seven major US cities.
