BOYNEXTDOOR is set to make their official debut in Japan on July 10th with their first single, 'AND,'. 

The single will feature four tracks, including Japanese versions of their hit songs 'One and Only' (from debut single 'WHO!'), 'Mwot Gata' (from mini-album 'WHY..'), and 'Earth, Wind & Fire' (from mini-album 'HOW?'), along with an original Japanese track.

Following the success of their mini-album 'HOW?' released in Korea in April, which garnered significant popularity in Japan, anticipation for their debut single 'AND,' is running high. 'HOW?' achieved nearly double the first-week sales compared to their previous release, securing the top spots on Oricon's weekly album ranking and combined weekly album ranking for the week of April 15-21. It also topped the Billboard Japan 'Hot Albums' chart for the same period and claimed the number one spot on Japan Line Music's 'Daily Album Top 100' for five consecutive days (April 17-21).

Additionally, BOYNEXTDOOR has been invited to perform at 'Summer Sonic 2024,' one of Japan's largest music festivals. 'Summer Sonic' attracts top artists from Japan and around the world and is considered Asia's premier urban music festival. Even before their official debut, BOYNEXTDOOR received invitations to several festivals, showcasing their unique performances and stage presence beyond their rookie status. With rave reviews for each performance, they garnered attention and ultimately received the invitation to 'Summer Sonic' before their official debut.
