South Korean boy band BigBang have embarked on eleven headlining concert tours, two of which have been worldwide, and six others in Japan. The group made their headlining debut in December 2006 through The R.E.A.L concert at Olympic Gymnastics Arena. In 2008, they embarked on their first Asian tour, The Global Warning Tour, visiting South Korea, Japan and Thailand. In 2009 and 2010, the band toured Japan on The Electric Love Tour and began annual concerts in Seoul called The Big Show. In 2011, after a two-year hiatus, the group released their EP Tonight, and planned to support the album with a world tour. However, multiple members encountered legal issues and the tour was cancelled. They visited Japan on their Love and Hope Tour, with part of the proceeds going to the 2011 Tōhoku earthquake and tsunami disaster relief.
