The second day of “2025 Show! Music Core in JAPAN” took place on Sunday, July 6, 2025, at the Belluna Dome in Saitama, drawing thousands of K-pop fans from across Japan and abroad. Building on the success of its inaugural edition in 2024, the live concert event—an extension of South Korea’s long-running and highly rated music program “Show! Music Core”—returned to Japan for its second consecutive year, once again presenting a powerful lineup of some of the most influential and fast-rising K-pop acts currently dominating the scene.
Day two of the event showcased a diverse mix of eight popular groups: aespa, ILLIT, INI, NCT WISH, NiziU, n.SSign, THE BOYZ, and TOMORROW X TOGETHER, each offering vibrant and distinct performances that energized the Belluna Dome from start to finish. Fans responded enthusiastically to the range of styles and stage productions, cheering passionately for their favorite idols while waving lightsticks and fan banners throughout the evening.
TOMORROW X TOGETHER brought the night to a close with a four-song setlist, including their emotionally resonant track “Love Language.” The group’s highly synchronized choreography and refined live vocals capped off the concert with impact. Member HUENINGKAI expressed his appreciation for the audience’s energy, remarking on the overwhelming enthusiasm that he and his members felt from backstage through to the final bow. The crowd responded with deafening cheers, cementing TXT’s role as the evening’s closing highlight.
Earlier in the night, aespa took the stage with four songs including their latest single “Dirty Work,” delivering a sleek and polished set that combined futuristic visuals and sharp choreography. Member NINGNING shared a heartfelt message with the audience, saying that the happiness of their fans—referred to as “MY”—is her own happiness. She promised continued growth and improvement, aiming to leave the audience with the impression that “aespa never disappoints.” GISELLE echoed the sentiment, adding that the day’s performance would remain an unforgettable memory for her and asking the audience if they, too, were feeling the same joy.
Among the evening’s highlights were two special cover performances created exclusively for this event and aligned with the summer’s theme, “PLAYFUL SUMMER!” NCT WISH performed “Miracle,” originally by Super Junior, and n.SSign delivered a dynamic rendition of SEVENTEEN’s “Super.” These collaborations offered rare opportunities for fans to experience reimagined versions of K-pop classics, presented with fresh arrangements and contemporary stagecraft. Both acts were met with loud applause and positive reactions from the crowd, many of whom expressed their excitement over seeing such unique stages that deviate from standard promotional sets.
The Belluna Dome itself contributed to the immersive experience with its scale and acoustics, providing a fitting venue for the production values typical of K-pop arena concerts. Light displays, synchronized VFX backdrops, and fan chants added layers of energy to the experience, making the event feel both intimate and grand at once.
Organized by the Show! Music Core in JAPAN Executive Committee, the two-day festival was held on July 5 and 6, with doors opening at 15:30 and performances beginning at 17:30 each evening. The full artist lineup over both days reflected a wide spectrum of K-pop talent—from emerging groups to established superstars. Day one included performances by Hearts2Hearts, IVE, izna, KiiiKiii, NEXZ, TAEMIN, TREASURE, and ZEROBASEONE, while day two featured aespa, ILLIT, INI, NCT WISH, NiziU, n.SSign, THE BOYZ, and TOMORROW X TOGETHER.
Show! Music Core,” originally launched in 2005 by major South Korean broadcaster MBC, has built a strong following among Japanese K-pop fans over the years, often referred to locally by its nickname “UmaChun.” Its extension into live performance events such as this one signals a continued effort to deepen ties with global fans and expand the footprint of Korean music culture throughout Asia. With consistently strong viewership and fan engagement, both the television broadcast and its affiliated concerts remain key touchpoints for international K-pop audiences.
