[Edaily Starin YUN GI BACK Reporter] The group NMIXX is set to make a full-scale push into the Japanese music market. They are marking a new beginning for their activities in Japan with the release of their Japanese debut best-of album.

According to their agency, JYP Entertainment, NMIXX will release their Japanese debut best album, “N=MIXX,” on December 9. The album features a total of 12 tracks, including “Blue Valentine”—which was a huge hit on domestic music charts—as well as Japanese-language versions of their previously released songs.
This album, released to commemorate their official debut in Japan, showcases N=MIXX’s musical identity and journey of growth. Having steadily established their presence with outstanding vocals and performances across every album—from their debut single “AD MARE” to their most recent release, “Heavy Serenade”—the group is expected to continue expanding their global reach through their activities in Japan.
NMIX is currently meeting fans around the world through their first world tour, “EPISODE 1: ZERO FRONTIER.” They kicked off the tour with a concert at the Inspire Arena in Incheon last November and, ahead of their official debut in Japan, are set to hold solo concerts at the Keio Arena in Tokyo on August 8–9 to connect with local fans first.
They are also steadily building a track record in overseas music markets. Their fourth mini-album *Fe3O4: FORWARD*, released last year, and their first full-length album *Blue Valentine* received critical acclaim from leading international media outlets such as the British music magazines *NME* and *Dazed*, as well as *Teen Vogue* in the U.S. Subsequently, their fifth mini-album *Heavy Serenade*, released in May of this year, ranked third on Billboard’s list of “Best K-Pop Albums of the First Half of 2026,” and the track “Crescendo” placed fifth in the “Best K-Pop of the First Half of 2026” category, demonstrating their global competitiveness.
