The venue was nearly full even before the concert began as a total of 13,000 passionate fans excitedly cheered on the boys. When iKON finally stepped onto the stage, the cheering was said to have grown to very high decibel levels! Amidst the fans' chants and screaming, iKON sang all their latest hits, including "Rhythm Ta," "My Type," "Airplane," "Apology," and even songs that were released before their official debut such as "Sinosijak" and "Wait for Me." 

iKON thanked their Japanese fans, saying, "Thanks to all you fans, we were able to stand on the Budokan stage so soon. We are so happy to perform at this place where we can feel the history."
