KO1KEYZ featured in new Meiji Bulgaria Yogurt commercial

The 12-member global boy group KO1KEYZ, formed through the survival audition program ‘PRODUCE 101 JAPAN New World’, has been selected for a new promotional campaign for Meiji Bulgaria Yogurt LB81 ONE SHOT.

The web commercial, titled ‘ONE SHOT: One Shout’, launched on October 13, 2026. The campaign concept encourages viewers to release daily frustrations by ‘shouting’ and attributing stress to gut bacteria, linking emotional relief to intestinal health. The group’s debut single, ‘KO1KEYZ’, is used as the commercial’s theme song.

In the advertisement, members appear through a large keyhole—a motif representing the group’s name—to express various relatable daily struggles before transitioning to a refreshing scene featuring the product. Meiji will also conduct a participatory social media campaign inviting fans to share their own frustrations.
