Japanese music fans in Korea are crying out with delight at the sheer number of acts making the trip over again this year. This isn’t a passing trend or a fleeting spike in interest—it’s evidence that J-pop, in its many shapes and forms, has genuinely taken hold here. There are long-awaited first visits, welcome reunions with artists who already have a devoted K-following, eager newcomers building their presence from the ground up, and all-time legends nobody can believe they’ll get to see live. Intimate concerts, big festivals, indoor and outdoor stages—music of wildly different flavors is descending on Korea this year, in all different ways. The range of options alone is enough to make this a year you can be excited about all throughout.
King Gnu, “CEN+RAL Tour 2026 in Seoul”
June 20 (Sat)–21 (Sun), KSPO Dome
King Gnu’s 2024 show here was unforgettable. The concert was something beyond electric, with the fans so enthusiastic that “explosive” would be a far better description. The cheering never let up, and the crowd sang along in one deafening roar. The band fed off that energy, at one point going into an impromptu rendition of “Tokyo Rendez-Vous.” The whole experience left such a deep impression on them that they even said so afterwards, eventually releasing some live recordings from the show for all to enjoy on the permanent record. That experience in Seoul, and across Asia more broadly, fed directly into two decisions: hosting an intimate show at a Zepp hall* exclusively for their fan club, and giving the whole crowd the go-ahead to take photos and videos. In a way, Seoul changed the whole way the band thinks about touring.
Two years later, the most notable thing about this upcoming visit is the 360-degree stage that the name of the tour hints at, meaning an entirely different use of space than the past, with stage production and overall atmosphere built specifically around that central stage. It’s also going to be a huge show, with over 10,000 attendees, so there’s real curiosity about the kind of chemistry that the sheer force of a crowd that size will have with the band. With a catalog built on a massive cross-section of genres, this is a chance to hear new material for the first time and make up for any songs that didn’t make the setlist two years ago. It should prove to be an unforgettable show where the crowd can come face-to-face with a spectacular band that never stops evolving.
*Zepp hall: midsize venue seating roughly 1,000 to 2,000
Aooo, “Echoes Weekend Seoul”
June 12 (Fri), YES24 WANDERLOCH HALL
Echoes is a Sony Music label launched in September 2024, built around the power of artists with deep ties to the Vocaloid scene—YOASOBI, Tatsuya Kitani, MAISONdes—and with a mission to more formally support web-based talent. Aooo is the label’s only band, and it’s something of a supergroup for their generation, bringing together artists who’d already made names for themselves elsewhere. Singer Riko Ishino proved her star power with AKAIKO-EN, guitarist THREEE was already a well-known Vocaloid producer, bassist Hikaru Yamamoto has been a backup player and overall director for YOASOBI, and drummer tsumiki pulls double duty as both a Vocaloid producer and a member of NOMELON NOLEMON. For those in the know, it’s clearly a stacked lineup.
Their performance at “WONDERLIVET 2025” went down well, and this upcoming visit’s shaping up to be a deeper, more fully loaded version of that, with a beefier setlist to match. At a time when crossover acts are dominating, there’s something that much more welcome about a band armed with nothing but pure rock. Heirs to the tradition of the “rockin’on” sound that dominated the 2000s and 2010s, Aooo pulls out all the stops to bring something genuinely new to it—as in songs like “SALAD BOWL”—and if you want a taste of something exciting and full of flavor, don't miss this upcoming show.
back number, “Grateful Yesterdays Tour 2026 Asia”
September 12 (Sat)–13 (Sun), KINTEX Hall 9
“I lost my girlfriend to a guy in a band. Getting dumped like that, I was just her back number.” It’s been some 20 years since the band took that experience—and that English term for an old issue of a magazine—and built a career around it. That origin story alone doesn’t define them, but the emotion running through the heart of their music is something like self-doubt—questioning whether you even deserve to love someone before you’ve made a single move. Being close by is good in itself, but you still find yourself “pulled away by the demon of summer,” wishing against all reason that they’d miraculously end up by your side—or, already in a relationship, getting ahead of your own shortcomings to ask (rather pathetically) for forgiveness in advance (“There’s a real chance the balance tips toward sorry sorry thank you sorry, but please forgive me”). It might read as a bit much on the surface, but listeners tend to find themselves projecting their own experiences onto the songs in the end. Their distinct way of capturing universally relatable feelings in everyday language is, more than anything else, what elevated the trio into an unparalleled band that plays to whole stadiums. What also works in this trio’s favor is, even with their guitar rock roots, they never lose their instinct for poppy melodies, meaning they can draw in listeners who wouldn’t normally gravitate toward the genre. There was already no shortage of fans here in Korea hoping they’d visit, but the buzz surrounding Sung Si Kyung’s recent performance of “Heroine” on a Japanese variety show has introduced the song to a much broader audience, and now the battle for tickets is only going to get fiercer. In place of flashy spectacle, what back number fills the stage with is something more honest and raw. What that vivid emotional sensibility sounds like live is something you’ll just have to experience for yourself.
eill, “ACTION ASIA TOUR 2026”
May 31 (Sun), YES24 WANDERLOCH HALL
Any artist considering putting a concert on abroad has to ask themselves whether there’s enough demand to justify the move. While the financial reality can’t be ignored, it’s becoming easier lately to see artists who aim to sidestep that logic entirely. You could say they’re pioneers—people who, even with little name recognition in Korea, believe in the shape of the market and its potential, and are determined to build their following here from the ground up. And that perfectly describes eill. Her roots are in R&B and soul—she was singing in jazz bars from around age 15—but the way she’s developed her career in multiple directions without being boxed into any one genre has echoes of K-pop idols. She’s had ties to Korea for a while, having worked on Japanese releases from TAEYEON and EXID, and since her 2023 festival work here, she’s put on two concerts of her own, slowly but surely expanding her foothold here.
This tour is an extension of her “ACTION TOUR” at home, which ran through February, and she’ll once again be moving freely between pop, rock, and dance in a set that covers the full breadth of her work. Since her last Korean show in 2024, she’s put out the album “my dream box” and the EP “ACTION,” so expect a healthy supply of new material in the setlist. This show comes at a moment when her relationship with Korean fans is just starting to hit its stride, and has something to offer whether you’re discovering her for the first time or already a fan. eill’s journey has been one driven by her determination to build an audience here, one show at a time, and her upcoming concert is a meaningful step toward her name taking real hold in the country.
Vaundy, “ASIA ARENA TOUR 2026 ‘HORO’ IN SEOUL”
September 19 (Sat)–20 (Sun), INSPIRE Arena
Everyone’s been waiting for what seems like ages, but this year, it’s finally happening—Vaundy’s coming to Korea. Vaundy, the defining 21st-century singer-songwriter, the youngest male soloist ever to do a stadium tour in Japan. Vaundy, the voice of a generation who put out more than 10 media tie-in tracks in 2025 alone. His deep involvement with theme songs for anime in particular means there’s a clear and substantial overlap with the core Korean audience for Japanese music, and it’s hard to think of anyone who’s made landfall here to greater anticipation. Ever since he debuted in 2019 with the song “Tokyo Flash,” everything he’s released has been in some way unpredictable, and he’s taken direct control of his own artwork and video direction along the way, showing what it means to be a multifaceted artist. His stop in Korea may feel overdue given how ardently his fans have been asking for this, but that just means there’s been that much more time for anticipation to build. No doubt, when the curtain finally lifts, he and his fans will experience something electric.
For Vaundy, a live show is a different kind of creative act from recording. Every performance has been a chance to try a new direction with new sound, a space to explore a creativity that only exists in that moment. Whatever he does in Korea—whatever takes place at INSPIRE Arena—it will no doubt be akin to him writing a new chapter in his personal history book. With a vast discography to draw from, there’s real anticipation around which songs will make the cut and how they’ll take shape onstage—and how music spanning such a wide spectrum will come together as a single live experience. This concert will be no less than a confident declaration on Vaundy’s part that the 21st century belongs to him.
“Asian Pop Festival 2026,” Day 1
May 30 (Sat), Paradise City
If you’ve been thinking “I feel like I’ve already seen all the big acts” or “I wish there was something a little different in the Japanese music space,” it might be time to take a step into more adventurous territory. The recent J-pop craze in Korea is unlike anything that’s come before, but a significant portion of it has been driven by demand from teens and twentysomethings for Vocaloid producers and anime theme songwriters. If that’s starting to feel a little played out to you, there’s a festival you might want to check out—one that builds its lineup around artists people keep coming back to regardless of what’s trending. That festival is the Asian Pop Festival, and it’s been drawing an increasingly serious crowd of music lovers.
There’s no question that the first of the event’s two days is the one that really stands out. Ohzora Kimishima’s unique world existing somewhere between rock, shoegaze, and punk … Quruli, who’ve occupied a one-of-a-kind genre-bending position on the map since forming the late ’90s … Rapper KID FRESINO sets himself apart with genre diversity, densely layered rhymes, and masterful control of tempo and tension … Hakushi Hasegawa and their pure, restless exploration of sound beyond the boundaries of pop music … Getting to see all of these singular artists on a single day isn’t the kind of opportunity that arises every day. And that’s not to mention Taeko Onuki, a member of SUGAR BABE—the group Tatsuro Yamashita was part of—and a living legend of Japanese city pop. Once you factor her in, there’s really nothing left to deliberate over. The Asian Pop Festival will show you Japanese music you didn’t even know you were missing—the kind of sounds that will completely reshape your sense of what Japanese music can be.
