First Ever Karaoke Box Collaboration: Big Echo Introduces Monaki-Themed Rooms Starting July 8

Daiichi Kosho Co., Ltd. (hereinafter "our company") will launch a collaboration project with four-member kayo group Monaki at Big Echo starting July 8, 2026.

Monaki-themed collaboration rooms—the first of their kind in any karaoke box—will be installed at the Big Echo Ikebukuro Nishiguchi Ekimae and Chayamachi locations. Additionally, collaboration drinks offering original merchandise will be available across a total of 30 stores, including these two locations.

Monaki is a group composed of members with unique backgrounds, including a former Super Sentai actor and former office workers, who debuted in April this year. The group gained attention as a product of "Second Chance Audition," produced by Ikkei Sakai, leader of the super sento idol group Junretsu. Their debut single, "Honmayade☆Nande Yane☆Shiranke do," has achieved over 1.5 billion total video views on social media platforms (as of June 29), marking an outstanding start.

Big Echo aims to increase customer satisfaction among existing fans and attract new fans—known as "Monakama" (fan nickname)—through this collaboration. The two participating stores will feature special collaboration rooms decorated with artist photos and logos, creating an immersive space where fans can fully enjoy Monaki's charm. At all 30 participating stores, fans can order member-inspired collaboration drinks and will receive, without exception, an exclusive pop-up coaster available only through this campaign. These Monaki-themed karaoke experiences are designed to encourage fan interaction and further energize the community.

Going forward, our company will continue to create appealing services that sensitively respond to customer needs, aiming to enhance customer satisfaction and promote karaoke usage at Big Echo.
