On June 6, 2026, a Japanese girl group performed at London's Wembley Stadium for the first time in history. XG, made up of JURIN, CHISA, HINATA, HARVEY, JURIA, MAYA and COCONA, played the UK's biggest summer music festival, Capital's Summertime Ball 2026, in front of 80,000 people. Three songs, roughly twenty minutes. Here is what happened, and why a British radio station picked this group for the moment.

What is Capital's Summertime Ball?

Capital's Summertime Ball is a stadium-scale pop festival hosted annually since 2009 by Capital, one of the UK's most popular commercial radio stations. Since 2010, it has been held at Wembley Stadium, the iconic 80,000-capacity venue in northwest London famous as the home of England's national football team and one of the world's largest covered stadiums.

Past performers read like a who's who of global pop: Taylor Swift, Ariana Grande, Sabrina Carpenter, Justin Bieber, Ed Sheeran, Harry Styles, Bruno Mars, Maroon 5, Coldplay, Katy Perry, Jennifer Lopez, Pharrell Williams, Miley Cyrus, and many more. The 2025 edition featured Mariah Carey, Will Smith, Jessie J, Rita Ora and JLS.

Highlights air on ITV1 and ITVX, and the show streams live worldwide on Capital's official app, Global Player, and on YouTube.

The 2026 Lineup and XG's Position

Capital's Summertime Ball 2026 took place on Saturday, June 6, 2026, at Wembley Stadium. Alongside XG, the lineup included:

  • Niall Horan (former One Direction)
  • Calvin Harris (king of summer anthems, his fourth Summertime Ball appearance)
  • RAYE (BRIT Award sweep winner known for "Escapism.")
  • Jason Derulo (returning after 11 years)
  • Lola Young (BRIT and GRAMMY Award winner)
  • Myles Smith (recent BRIT winner who toured with Ed Sheeran)
  • Fatboy Slim (making his Summertime Ball debut)
  • Take That (added in a later announcement)
  • Bebe Rexha, Robyn, Sienna Spiro, Stephen Sanchez, MEEK, December 10, Sekou

Capital introduced XG as "the international dance pop group" and as their 2026 Capital Buzz Artist, a slot reserved for the act the station is championing hardest. That framing reflects how heavily UK radio is now invested in XG.

Since the festival began in 2009, no Japanese act had ever appeared on its lineup. XG also became the first Japanese artist group ever to perform at Wembley Stadium.

The Only Japanese Wembley Performance Before Was 29 Years Ago

There has been exactly one prior instance of a Japanese artist performing at Wembley Stadium: on August 16, 1997, rock legend Eikichi Yazawa appeared as the Asian representative at "Songs and Visions," a festival commemorating the 20th anniversary of Elvis Presley's death. That was the old Wembley, though. It closed in 2000 and was demolished; the current stadium is a different building, opened in 2007.

Yazawa shared the stage that night with Rod Stewart, Jon Bon Jovi, Chaka Khan, Robert Palmer, and Mary J. Blige. Reports from the time noted that most of the 70,000 attendees had no idea who he was when he walked on, but his rendition of Elvis's "Don't Be Cruel" reportedly won the crowd over by the end of his set.

Nearly 29 years later, XG stepped onto that ground not as a solo artist but as a seven-member group, and onto the rebuilt stadium at that. It was the first Wembley performance by a Japanese artist group.

Who is XG?

XG is a seven-member girl group consisting of JURIN, CHISA, HINATA, HARVEY, JURIA, MAYA, and COCONA. The name stands for "Xtraordinary Genes," reflecting the group's mission to "broadcast a BOLD culture to the world" through music and performance that refuses to be confined to convention.

All members are Japanese, but the group sings primarily in English. Their sound spans hip-hop, R&B, house, and UK garage, and their primary market has always been global, not domestic Japan. Since debuting in March 2022 with their first single "Tippy Toes" under the Japanese-Korean entertainment production company XGALX, they have appeared at roughly 20 international music festivals.

How XG Built Up to Wembley

XG didn't suddenly land at Wembley. Their booking is the result of a methodical international ramp-up:

2024–2025: First World Tour "The First HOWL", 47 shows across 35 cities worldwide, drawing roughly 400,000 attendees. Their Tokyo Dome show made them the first Japanese girl group ever to headline that venue.

April 2025: Coachella, XG were the only Japanese act on the Coachella Valley Music and Arts Festival 2025 lineup. They closed out the Sahara stage, the festival's largest indoor stage, making them the first Japanese act ever to do so. The performance hit #2 on global X (Twitter) trends and #2 in the US, charting in the top 5 across 11 countries and regions.

January 2026: First Full Album "THE CORE", Released on January 23rd, the album marked their first entry into the top 100 of the US Billboard 200. Single "HYPNOTIZE" simultaneously hit #1 on Billboard Japan Songs in 7 different countries.

Now: Second World Tour "XG WORLD TOUR: THE CORE": still underway. It opened with three sold-out nights at K-Arena Yokohama in February (around 60,000 attendees) and covered 16 shows across 8 Japanese cities. After Wembley the group moved through Asia, playing Bangkok on July 19 and Manila on July 22, with North America, the UK and Europe, Australia and Latin America still to come.

2026 Summer Festival Schedule: XG play Fuji Rock '26 on July 25, their debut at Japan's most prestigious rock festival, then perform as second headliners at HEAD IN THE CLOUDS Music & Arts Festival in Los Angeles on August 8. They return to London on September 2 for their own headline show on the THE CORE tour.

The Set: Three Songs, Twenty Minutes

XG took the stage at 7:20 PM local time, with doors having opened at 1:30 PM and the stadium at its 80,000 capacity. Their slot ran about twenty minutes.

They opened with "HYPNOTIZE" from their first full album. For the second song they reached into British music history and covered "Flowers" by Sweet Female Attitude, a UK garage classic, in a one-off world exclusive. They closed with "SOMETHING AIN'T RIGHT."

Capital wrote afterwards that in the space of three songs XG had proved exactly why they are one of the biggest and best groups in the world right now. Tickets, as in recent years, had sold out within hours of going on sale, and fans travelled in from well outside the UK for the set.

XG's Global Fandom: ALPHAZ

XG's worldwide fan community is called ALPHAZ, derived from "Alpha," the leader of a wolf pack. The name reflects the group's vision that "each fan can become a leader, connect with XG, and be part of a movement reshaping the world."

The official ALPHAZ fan club app supports eight languages: Japanese, English, Korean, Simplified Chinese, Traditional Chinese, Spanish, Portuguese, and Arabic. Posted comments are auto-translated, and fans across countries traded reactions in real time throughout the Wembley set.

Why XG Is Resonating in the UK Right Now

UK music outlets covering the announcement repeatedly emphasize the same point: XG don't fit neatly into any nationality-bound or genre-bound box.

Electric Bloom Webzine framed the booking as a history-making moment. London Now characterized XG as a group reflecting a growing global presence through genre-mixing hits. That framing, plus Capital's decision to slot XG into the prestigious Buzz Artist spot, suggests the UK pop establishment is consciously positioning XG as the next-generation Asian pop act for British audiences.

Their distinct positioning as "X-POP" (neither J-POP nor K-POP), their Japanese membership combined with a globally-anchored operating model, and their viral momentum on TikTok and Spotify all converge to explain why a British radio station chose XG for this moment.

What This Means for the Wider UK Music Scene

XG's Wembley appearance carries weight beyond a typical "Japanese act goes overseas" story.

First, a Japanese girl group has made it onto a mainstream UK pop festival lineup not through traditional J-POP export channels, but through a streaming-era global music consumption pipeline. Second, an Asian girl group sharing a stage where Taylor Swift and Harry Styles have headlined is, in itself, a small but real shift in the geography of British pop culture.

The festival was streamed live worldwide via Global Player and YouTube, with highlights on ITV1 and ITVX, so ALPHAZ everywhere watched the twenty minutes as they happened.
