Japanese Dancehall sound system Mighty Crown hosted their 20th anniversary in Yokohama, Japan on May 3, 2011.

The turn out was massive in light of recent threats from radiation in the Asian country. The event features appearance from Mighty Crown, Tony Matterhorn and Banky Hype. According to a rep for Mighty Crown, a series of other shows are planned throughout the summer.
