SS501 Members Kim Hyun Joong, Heo Young Saeng, and Kim Kyu Jong Reunite as ‘FIVE O ONE’ for 20th Anniversary World Tour

The long-awaited reunion of SS501 members Kim Hyun-joong, Heo Young-saeng, and Kim Kyu-jong is finally happening!

On May 1st, their agency Henecia officially announced that the trio is launching a special project under the new unit name FIVE O ONE to commemorate the 20th anniversary of their debut.

Henecia stated, “SS501 members Kim Hyun-joong, Heo Young-saeng, and Kim Kyu-jong are preparing a project to celebrate their 20th debut anniversary. This will be a gift to fans who have waited for a long time. Through a world tour beginning in Seoul this July, the members will reconnect with fans across the globe.”

SS501, which debuted in 2005, is widely recognized as one of the iconic second-generation K-pop boy groups. With hits like “Snow Prince,” “Love Like This (네게로),” “UR MAN,” and “Because I’m Stupid,” the group captivated audiences in South Korea, Japan, and beyond. Over the years, the members have pursued successful solo careers, but the deep bond between them and their loyal fandom has endured.

Now, under the name FIVE O ONE, Kim Hyun-joong, Heo Young-saeng, and Kim Kyu-jong are coming together to relive their legacy and build new memories. Their upcoming world tour will not only celebrate their two-decade-long journey but also spotlight their evolution as artists. Kicking off in Seoul in July, the tour will span multiple countries, providing a long-awaited reunion for their international fanbase.

Of particular interest is their popularity in Japan, where SS501 enjoyed massive success. With the return of these three members, anticipation is growing around the possibility of reigniting their global presence and solidifying their standing as one of K-pop’s original global powerhouses.

To mark the announcement, a comeback teaser video has been released via the group’s official YouTube channel. The teaser features a dark and dramatic visual tone, with the sound of a heartbeat echoing in the background—symbolizing both anticipation and the emotional pulse of the group’s return. The brief clip, featuring silhouettes of the members shrouded in shadows, sets the stage for an emotional and powerful comeback.

Henecia also revealed that additional content related to this anniversary project will be released sequentially through the company’s official social media channels. Fans can look forward to behind-the-scenes footage, messages from the members, and more updates as the July kickoff approaches.

As the members reunite as FIVE O ONE, the project is being seen as more than just a nostalgic revival—it’s a celebration of legacy, growth, and enduring connection. With the world tour ahead, SS501’s journey is far from over, and a new chapter is just beginning.
