BEAT AX is bringing back its summer showcase, and the Boys Day lineup is officially locked in. FANTASTICS, MAZZEL, BUDDiiS, Lienel, and BMSG TRAINEE will take the stage on July 10 at Kアリーナ横浜in Yokohama, with the Girls Day event following on July 12.

BEAT AX started in 2023 as a Nippon Television-backed music event, and this summer edition splits programming by gender. The Girls Day lineup already announced includes =LOVE, Ave Mujica, and RAISE A SUILEN—three acts ready to kick off the weekend before the Boys Day crews step in.

The five groups performing July 10 represent different corners of Japan's music scene. FANTASTICS brings LDH's established boy group energy, while MAZZEL and BUDDiiS represent newer generation sounds. Lienel and BMSG TRAINEE round out the billing with rising talent.

Fans interested in catching either day can find full ticket details and event information on the official BEAT AX website. The Yokohama arena shows promise for a solid summer music event—expect the usual mix of performances, collaborations, and the kind of energy these broadcast-backed events typically deliver.

The two-day format gives fans options: catch the boys on the 10th, the girls on the 12th, or make it a full weekend experience. It's a solid reminder that Japan's music festival scene continues to evolve beyond traditional summer outdoor events, with venues like Kアリーナ providing indoor alternatives that work year-round.
