Hearts2Hearts Releases ‘ICONIC HEART’ in Korean
Hearts2Hearts unveiled a teaser for “ICONIC HEART (Korean Ver.)” at midnight KST on October 5, 2026. The full digital single arrived at 6 p.m. KST that same day. Three days earlier, on October 2, the group gave the song its first live performance at Spotify CLOSER, held at MYUNGHWA LIVE HALL in Seoul. That stage came before any digital release, giving Seoul audiences the first listen to the Korean lyrics.
The Four No. 2 Japan Chart Peaks
The original “ICONIC HEART” reached No. 2 on four Japanese charts. It peaked at No. 2 on the Oricon Weekly Singles Chart and No. 2 on the Oricon Combined Singles Chart. On Billboard Japan, it also reached No. 2 on both the Hot 100 and the Top Singles Sales chart. The Korean version arrives after these four peaks, turning a song built for the Japanese market into a release aimed at Korean and global listeners.
What Changes in the Korean Version
Kenzie participated in writing the Korean lyrics. The production keeps a Jersey club base, built around lively synthesizers and a bouncing beat. According to MK, the Korean version carries a theme about moving toward a wider world together. The core production style stays close to the Japanese original, but the language and lyrical content are new.
What Is on the Original Japanese Single
The Japanese “ICONIC HEART” single launched digitally on August 10, 2026, running nine minutes across three tracks. A physical single followed on August 12, 2026, marking Hearts2Hearts’ Japanese debut less than 18 months after its February 2025 Korean debut.

Global Release Times
For Southeast Asian fans, the October 5 release landed at 4 p.m. in Indonesia, Thailand and Vietnam, and at 5 p.m. in the Philippines, Malaysia and Singapore. North American listeners got the song at 5 a.m. EDT and 2 a.m. PDT. In Latin America, release times were 3 a.m. in Mexico City, 4 a.m. in Peru and Colombia, and 6 a.m. in Brazil and Argentina.
Why Hearts2Hearts Has Momentum
Hearts2Hearts debuted on February 24, 2025, with “The Chase.” The single sold 408,880 copies during its first tracking week, from February 24 to March 2. That total set a Hanteo record for a girl-group debut, passing the previous mark of 401,287 copies set by BABYMONSTER.
What the Release Tests
The group has a verified Japanese chart record to point to, but turning a Japan-market song into a Korean release tests whether that success carries over without a new song cycle. The four No. 2 peaks are real; whether Korean listeners respond the same way is the open question this release answers.
