Hearts2Hearts recorded the highest first-week sales among Japanese debut releases by 5th-generation K-pop girl groups, according to a recent SoundScan Japan comparison. The eight-member group, made up of Jiwoo, Carmen, Yuha, Stella, Junn, A-na, Ian, and Ye-on, released their Japanese debut single, “ICONIC HEART,” on August 12, 2026. The track sold 65,176 copies during its first tracking week, surpassing the 54,187 and 5,764 copies recorded by the other two releases examined.
The title track had a strong entrance on the Billboard Japan Hot 100, entering the chart at #2 during the same tracking period. “ICONIC HEART” was released in six different formats, including a regular edition and several first-press limited editions featuring photobooks, profile sheets, postcards, and other special items. The single also included “RUDE! (Japanese Ver.)” among the three tracks on the releases, alongside “Lemon Tang (Japanese Ver.).”
Hearts2Hearts has been intentionally trying to break through the Japanese music scene! Their activities included an SMTOWN LIVE 2025 performance in Tokyo in August 2025, a release event at DiverCity Tokyo Plaza in December, and the digital release of “RUDE! (Japanese Ver.)” in March 2026. Between April and June, they also appeared on Japanese television. In August, they continued their momentum through festival appearances, THE FIRST TAKE, and TOKYO GIRLS COLLECTION events.
