MAMAMOO has opened the teaser rollout for its full-group comeback with the first teaser for “4WARD,” released at midnight KST on May 7. The MAMAMOO 4WARD teaser was presented with the wording “COMING SOON,” while an exact comeback date had not been announced in the cited report.1
The teaser is the first public marker in the group’s latest four-member comeback campaign. It follows earlier confirmation from RBW that Solar, Moonbyul, Wheein and Hwasa are preparing a full-group album for June 2026, with a large-scale world tour planned as part of the same 12th-anniversary project.2
MAMAMOO 4WARD Teaser Starts the Comeback Countdown

The first “4WARD” teaser gives the comeback campaign an official title but leaves several release details open. The available source material confirms the teaser timing, the “COMING SOON” label, and the connection to a four-member comeback, but it does not provide a tracklist, album format, release time, concept description, or music video schedule.1
That limited disclosure is consistent with an initial teaser stage. The confirmed facts point to a June full-group album rather than a standalone teaser project. Soompi reported on May 6 that the teaser arrived at midnight KST on May 7 and noted that no comeback date had been announced in that report.1
The broader comeback plan was first laid out months earlier. RBW’s announcement, carried by Starnews and Soompi on December 31, 2025, confirmed a new full-group album in June 2026 and a major world tour to follow.23 In the English-language version of the announcement quoted by Soompi, RBW said, “MAMAMOO is confirmed to release a new album as a full group in June 2026, and they will also embark on a large-scale world tour.”3
The June timing is significant because it aligns with the group’s 12th debut anniversary project. Source material identifies the participating members as Solar, Moonbyul, Wheein and Hwasa, preserving the full-group framing around the comeback and tour.2
June Album Plans and Anniversary Tour Context
The “4WARD” teaser arrives after multiple reports established June 2026 as the target window for MAMAMOO’s full-group return. OSEN reported on April 3 that the group would make a full-group comeback in early June and begin a large-scale world tour tied to its 12th anniversary.4
The tour is scheduled to begin in Seoul on June 19, the group’s debut anniversary. OSEN reported that the tour would continue to cities including Kaohsiung, Macau, Singapore, Manila, New York, Chicago, Fort Worth, Cedar Park, Los Angeles, San Jose, Tacoma and Hong Kong, and said the tour would include stages for new songs.4
Dispatch’s DIPE also reported on April 3 that MAMAMOO was set to return as a full group in June as part of a 12th-anniversary project. The same report said the group unveiled a 2026 world tour announcement poster on April 3, with the tour beginning in Seoul on June 19 and an “and more” note indicating that additional stops could follow.5
The tour scale had previously been described as a 26-city plan across Asia, the Americas and Europe. Starnews reported that RBW confirmed the June 2026 full-group album and 26-city world tour as a global project for the group’s 12th anniversary.2
For readers following the MAMAMOO 4WARD rollout, the key point is that the teaser is not isolated from the group’s wider 2026 schedule. The confirmed June album plan, Seoul opening date, and announced international itinerary place “4WARD” within a larger comeback-and-tour framework rather than a single teaser drop.
U.S. Tour Ticket Timing
SBS News reported on May 1 that MAMAMOO will hold a U.S. tour in seven cities, beginning in New York on August 12. The report listed Chicago, Fort Worth, Cedar Park, Los Angeles, San Jose and Kent among later stops, and connected the U.S. dates to the group’s June full-group comeback and broader world tour plans.6
Ticket sales for the U.S. dates are set to proceed through Ticketmaster, with presale scheduled for May 13 and general sale scheduled for May 15.6 Those ticket dates are separate from the still-unannounced exact album release date for “4WARD” or the full comeback project.
