As part of Katsushika Ward’s “Katsushika, the City of Music” initiative, this music event was launched to commemorate the 30th anniversary of Katsushika Symphony Hills. Ten rock-oriented amateur bands, mainly active within the ward, will gather at the Mozart Hall to deliver a wide variety of performances. The guest act is Alaska Jam, known for its one-of-a-kind style that fuses hip hop and guitar rock. Scheduled for February 2026, admission is free and no reservation is required.
