MAMAMOO Returns With '4WARD': First Full-Group Comeback in Four Years Launches a 26-City World Tour in 2026

MAMAMOO's '4WARD' comeback in 2026 is not simply a new single — it is the first full-group release from Solar, Moonbyul, Wheein, and Hwasa in nearly four years, arriving alongside a 26-city world tour that confirms RBW Entertainment's most ambitious promotional arc since the group's commercial peak. The special single drops June 4 at 6 PM KST, and the scale of what follows — Seoul arena dates, US cities from Chicago to Los Angeles, and European stops — signals a reunion built for maximum reach.

The last time MAMAMOO released music as a complete four-member group was October 2022's 12th mini-album 'MIC ON.' In the nearly four years since, Solar, Moonbyul, Wheein, and Hwasa have remained individually prolific — Solar's 'WANT' era, Moonbyul's solo discography, Wheein's studio work, and Hwasa's continued crossover activity have each built substantial independent audiences. '4WARD' arrives not as a revival but as a recalibration: a statement that the group's collective identity remains the primary unit.

June 2026 carries additional weight as it aligns with MAMAMOO's 12th debut anniversary window. RBW has structured the comeback accordingly — releasing concept photos in May that the group's fanbase described as radiating a refreshing, summery energy, followed by the promotion scheduler that maps a full rollout through the summer tour launch. The '4WARD' title functions as both a direction (forward) and a signature (the four members who anchor it).

The tour opens in Seoul with a three-night run at a major arena venue from June 19 to 21 — the home-market anchor before a summer sweep through Asia. Asian dates include Kaohsiung (July 4), Macau (July 18), Singapore (July 31), and Manila, with more Asian cities expected to be announced. The '4WARD' World Tour then crosses to North America: Chicago's Wintrust Arena on August 15 leads a US leg that also takes in New York, Fort Worth, Cedar Park, Los Angeles, San Jose, and Tacoma. European dates round out the 26-city itinerary.

For MAMAMOO, a 26-city world tour in 2026 is genuinely unprecedented in scope. Their previous touring activity — strong in Asia, selective in the West — never reached this geographic footprint while all four members were active as a unit. The scale of the '4WARD' tour reflects both the accumulated goodwill from four years of solo work and a deliberate decision to reintroduce the group to global markets at a moment when K-pop's international infrastructure can support the kind of arena-level production the tour demands.

MAMAMOO occupies a specific position in K-pop history: a group whose commercial success was built primarily on vocal chemistry and genre versatility rather than on the idol-system machinery of larger companies. Their reputation for live performance — earned across years of televised stages and sold-out venues — is the foundation '4WARD' is drawing on. Fans have noted that the group's social media reactivation in the lead-up to the release carries the same energy as their earliest-era content: all four members interacting across platforms in ways that had slowed during the solo years.
