The film premiered in 56 theaters across Japan on September 13, 2019. Extra showings were added at 22 theaters on October 25, 2019.
The film's teaser also revealed that BanG Dream! 3rd Season would debut in January 2020, instead of the initially announced October 2019.
It's here! The big concert! Kasumi Toyama, the girl who followed the trail of golden stars and heard the call of the Star Beat, and her friends/bandmates Saaya, Tae, Rimi and Arisa, are now poised on the edge of stardom themselves as they prepare for a massive outdoor concert! It's a huge venue to fill, but fortunately Poppin'Party won't be the only band taking the stage during this major musical event. It's a non-stop wall of J-Pop fun as Afterglow, Pastel Palettes, Roselia, and Hello, Happy World! all join the ladies of Poppin'Party, and while they're all still competing against each other, the real winners are the lucky members of the audience!
