SYUTO shared a photograph of CANNONBALL GAIDEN’s artist banner following the festival’s final day at Ariake Arena. The large display contains messages and signatures left by performers who participated in the three-day event, including BABYMETAL.
BABYMETAL left their mark at Ariake Arena
Near the upper center of the banner, fans can spot a BABYMETAL inscription accompanied by the date “2026.08.10,” commemorating the group’s appearance on the second day of CANNONBALL GAIDEN.
BABYMETAL performed at Ariake Arena on August 10, while the festival ran from August 9 through August 11. The signed display has now become a visual record of the many artists who took part in the event.
Shared by SEIKIMA-II support keyboardist SYUTO
SYUTO—also known as KAMISORI SYUTO in his work as a support pianist and keyboardist for SEIKIMA-II—posted the photograph during the event’s final day.
In his message, he celebrated SEIKIMA-II’s appearance at Ariake Arena, said he had a great time and jokingly described his hairstyle for the day as resembling an axolotl.
Beyond documenting the final performance, his photograph offered BABYMETAL fans a closer look at the group’s signed contribution to the CANNONBALL GAIDEN banner.
