September 2026 K-pop Comebacks

The story of September 2026

September carried most of its weight at the front. The weekday runs from the 1st through the 4th and the 7th through the 11th were crowded with albums and singles; the 9th drew the month's biggest cluster, crossing Korean and Japanese releases. Release times varied too: September 4 stretched from 09:00 to 18:00 KST, while the 7th leaned into an 18:00 KST block around SOYEON (i-dle)'s full album 끝내주는 인생 (What a Wonderful Life). IU's 이 별로부터 followed on the 10th.

The pace eased into smaller clusters around mid-month. September 14 put Japanese releases alongside Korean albums and singles, with IRENE & SEULGI (Red Velvet)'s Japanese mini album Cheetah sharing the date with The Volunteers' full album i love u. The 15th gathered Korean releases at 18:00 KST; Japanese titles dominated the 16th, with Redoor's mini album Memory adding a Korean release. September 18 kept to Korean releases but spread them across the day, from ROSÉ's new trick at 08:00 KST through HONGJOONG (ATEEZ) at 13:00 KST to CLOSE YOUR EYES and SORAN at 18:00 KST. SORAN's EP Layer broke up that day's run of singles.

September 21 brought another large cluster of Korean and Japanese releases, then the line-ups thinned through the 23rd. The calendar picked up again on September 25 with dearALICE's UK EP dancefloorKILLA alongside Korean singles. Korean releases then carried the quieter dates on the 26th and 27th. September 28 stretched from JUN (SEVENTEEN)'s EP 9 at 11:00 KST to a larger 18:00 KST block around BOYNEXTDOOR's repackaged HOME: DELUXE. The 29th kept to singles; the 30th broadens the mix again, bringing Japanese titles together with Korean mini albums from CLOSE YOUR EYES and CRAVITY. Our release types explained guide unpacks the repackage label, and the September preview follows the full schedule.
