Rock in Japan Festival in Chiba
Rock in Japan Festival, founded in 2000 by the magazine Rockin'On Japan, is the largest rock festival in the country by total attendance, focused heavily on domestic Japanese rock and pop-rock acts. Held at Hitachi Seaside Park through 2014 before relocating to Chiba's Soga Sports Park, it now spans two consecutive weekends in early August, drawing crowds regularly exceeding 60,000 per day.
Founded in 2000 by the influential music magazine Rockin'On Japan, the Rock in Japan Festival grew to become, by total attendance, the largest rock festival held anywhere in the country, a scale achieved through a combination of extensive multi-day programming and a deliberate focus on Japanese domestic rock and pop-rock acts rather than international headliners.
