On January 3, 2026, Poppin'Party New Year LIVE “Happy BanG Year!!” was held at the Tokyo Garden Theater.
The show opened with the members showcasing their kakizome (New Year’s calligraphy) before starting the performance with their 1st Single title track, “Yes! BanG_Dream!” During the following MC, it was announced that the setlist for the night would be determined by the squares of a sugoroku (board game). When the game landed on the “Hatsumode” (First Shrine Visit) square, the performance of the second song, “What’s the POPIPA!?” featured a moment during the bridge where all members offered prayers in front of a stage set designed like a torii gate.
