Former TOZ Member HART Opens Up About Sex Life, Reveals Past Experience

TOZ (티오지) was a four-member Japanese boy group formed by contestants from Mnet's audition program BOYS PLANET. The group officially debuted in Japan on September 27, 2023, with their first mini-album FLARE. On May 2 of the following year, they released their first Korean mini-album, TO my new friends, marking their entry into the Korean music scene. However, their group activities were short-lived. Their agency, YY Entertainment, announced on October 31, 2025, that after discussions, they decided to conclude TOZ's group activities, with the four members pursuing individual entertainment careers.

Among the members, HART (Haruto) had previously competed in multiple Korean audition programs. In 2021, he participated in SBS's LOUD, advancing to the fourth round before being eliminated. In late 2022, he joined BOYS PLANET as a trainee under WAKEONE, ultimately finishing in 22nd place in episode 11, missing out on joining the project boy group ZEROBASEONE.

In 2023, HART joined YY Entertainment and formed TOZ with Anthony, Yuto, and Takuto, who also participated in BOYS PLANET. During the group's activities, he used "HART" as his stage name.

Now that TOZ's group activities have concluded, HART has once again drawn attention for his candid discussions about his private life. He recently appeared on the YouTube show todos son wueones menos yo, where he engaged in various conversations with the host, repeatedly touching upon the topic of "sex" with remarkable openness.
