Who Is ROIROM?
ROIROM is a Japanese male idol duo formed by Honda Hiromu and Hamagawa Roi, two finalists from the Netflix audition program timelesz project -AUDITION- (commonly known as “Taipuro”). The audition was organized by the members of timelesz (formerly Sexy Zone)—Kikuchi Fuma, Sato Shori, and Matsushima Sota—to find new members for their group.
Although both Honda and Roi reached the final round of the audition, they were not selected to join timelesz. However, their impressive performances and strong fan support during the show created significant momentum. After the audition concluded, the two decided to form their own duo, announcing their formation on May 8, 2025, through simultaneous Instagram posts.
The group’s journey has been marked by rapid success. Within months of formation, they held their first solo showcase at Ariake Arena on November 23, 2025, drawing approximately 20,000 attendees. They have since released pre-debut material, secured brand ambassadorship, and made their major debut under Victor Entertainment in 2026.
Group History
Formation and Pre-Debut
ROIROM’s formation is deeply rooted in the timelesz project -AUDITION-, which aired on Netflix starting September 13, 2024. Honda Hiromu and Hamagawa Roi were among the contestants who advanced to the final round. Roi, in particular, was described as a “surprising candidate” from his very first appearance.
Before the timelesz project, both members had already crossed paths. In 2023, they participated together in the Chinese audition program ASIA SUPER YOUNG (亞洲超星團) alongside fellow agency member Nishiyama Tomoki, performing as a trio called “Cat’s Eye Brothers” (貓眼三兄弟). Honda ranked 44th in that competition, while Roi achieved the highest ranking among all Japanese contestants.
Honda had previously participated in PRODUCE 101 JAPAN Season 2 in 2021, where he finished in 83rd place.
After the timelesz project ended, both Honda and Roi were considering their next steps independently. They discovered they shared similar aspirations and decided to pursue activities together as a duo. On May 8, 2025, at 12:00 PM JST, they simultaneously updated their Instagram accounts to announce the formation of ROIROM, coinciding with the launch of their official fan club.
Official Debut
ROIROM’s major debut was officially announced on April 14, 2026, by Victor Entertainment.

This was followed by the release of their debut mini-album, also titled “CLASSIC WAVE,” on June 10, 2026.
The mini-album features seven tracks, including “CLASSIC WAVE,” “AYE” (for which both members contributed lyrics), “ZEROGRAVITY,” “DRESS CODE,” “I SITE U♡,” “Pa Ri Ra!!,” and “Dokkade”.
Breakthrough Success
ROIROM’s breakthrough came during their pre-debut phase. Their first solo showcase, ROIROM debut showcase ～dear cHaRm～, held at Ariake Arena on November 23, 2025, attracted approximately 20,000 attendees. At this event, they performed original songs including “Dear DIVA,” which had been released as a pre-debut digital single on November 19, 2025.
