Summer Sonic (サマーソニック, Samā Sonikku), is an annual music festival held on one weekend in August simultaneously in both Chiba and Osaka, Japan. The festival features revolving lineups performing one day in Osaka then performing the next day in Chiba and vice-versa. The lineup often features major international acts in addition to Japanese artists from major and independent record companies.

The festival was first held in 2000 at Fuji-Q Highland resort in Yamanashi Prefecture. The festival moved to Chiba in 2001, just east of Tokyo, and has occurred in both Chiba and Osaka simultaneously since 2002. Since 2011 the festival has been preceded by the all-night event Sonic Mania, a separately ticketed event held in Chiba only featuring an EDM-centric lineup. The 2009 and 2011 editions of the festival were held over three-days while all other editions of the festival have been two-days. International versions of the festival have occasionally been held outside of Japan, including Shanghai in 2017 and Bangkok in 2024.^[1][2]
