Kim Jaejoong's KEYVITUP Is His First Boy Group, Debuting April 8

KEYVITUP (키비타업), the five-member boy group produced by K-pop legend Kim Jaejoong, will officially debut on April 8, 2026 with their self-titled first EP under iNKODE Entertainment, per the label's official debut announcement released in March. It marks a milestone for the former TVXQ and JYJ member: his first time stepping behind the scenes to launch a full male idol group from the ground up. The five members, Taehwan, Hyunmin, Sena, Jaein, and Rukia, represent a mix of Korean and Japanese talent chosen through iNKODE's INTHE X trainee showcase. The debut EP arrives in three versions (KEYVITUP Ver, LEGENDARY Ver, and Random), a multi-version strategy designed to maximize first-week Hanteo chart certification. For a debut this front-loaded in terms of strategy and production resources, the only question left is whether the music matches the ambition.

KEYVITUP doesn't just carry Jaejoong's name. It carries his expectations. He's not producing this group from the outside; he built iNKODE Entertainment specifically to develop acts with his own artistic vision. After launching girl group SAY MY NAME, the boy group chapter is now open, and the concept photos already suggest this debut means business.

Meet the Five Members

KEYVITUP is a five-member group consisting of Taehwan, Hyunmin, Sena, Jaein, and Rukia, a blend of Korean and Japanese members selected from iNKODE's INTHE X trainee showcase. The group positions itself as a true all-rounder unit, where no single member is pigeonholed into one lane.

Taehwan, the eldest, holds down the main vocalist position and brings a steady vocal foundation to the group's sound. Hyunmin, the leader, is the group's multi-threat covering dance, vocals, and visuals with the kind of meticulous attention you'd want from a team captain. In behind-the-scenes footage, members have described him as the group's anchor, the one who keeps everyone calibrated. Sena brings the visual center with a presence on stage that's been called singular and high-energy. Jaein joined under a vocal designation, then promptly exceeded it by excelling in dance and rap too. Exactly the all-rounder profile iNKODE claims to be building. Rukia, the youngest, is KEYVITUP's main dancer and mood maker. The charisma-to-age ratio on display in promo footage already has fans paying close attention. All five were selected through iNKODE’s INTHE X trainee program, which documented the selection process on YouTube and gave fans early visibility into the group’s formation ahead of the April 8 debut.

The group's stated vision: "KEYVITUP always means a group that grows as it goes forward." Continuous upward movement is the brand identity they're betting on from day one.

The Kim Jaejoong Factor

Kim Jaejoong needs no extended biography for anyone who's followed Korean music for more than five minutes. As a core member of TVXQ and later JYJ, he's one of the most globally recognized figures from the second-generation K-pop era. That history isn't background noise. It's actively part of how KEYVITUP is being positioned. Jaejoong isn't a silent investor in iNKODE. He's the creative force directing the group's vision.

What makes this debut interesting isn't just the legacy attached to it. It's the scope of what iNKODE is building. Per AllKPop reporting, iNKODE is launching not one but two boy groups in 2026: KEYVITUP in April and a second group, VAY ONN, targeting a June debut. That's an aggressive expansion for a still-young label that already has SAY MY NAME in its roster. Jaejoong is building something deliberate here, not a one-off project. For context: he spent years at the center of K-pop's most publicized legal disputes, when TVXQ's 2009 split fractured a fanbase that had grown across Asia for nearly a decade. That experience of watching creative control disappear from under your feet shaped exactly the kind of label he built when he finally had the leverage to build one. iNKODE is not a vanity project. It is a correction. KEYVITUP isn't just his first boy group. It's the clearest statement yet of what kind of industry player he intends to be.

KEYVITUP's concept photos, released across March 12 and 13, made the aesthetic direction clear: black leather, futuristic backdrops, and a "classy yet rugged" approach that reads as urban-editorial without leaning too hard into any single reference. Sharp lines, controlled atmosphere. It's not a soft launch.

What to Expect on April 8

The debut EP is self-titled, a statement that this first release is about establishing who they are before anything else. Three album versions (KEYVITUP Ver, LEGENDARY Ver, Random) offer fans multiple ways to engage with the physical release, a strategy that's become standard practice for groups trying to maximize chart certification from the jump.

The group has also released a documentary series, NO CAP: THE MAKING OF KEYVITUP, which offers candid member introductions and behind-the-scenes footage from the lead-up to debut. It's the kind of content that builds fan connection fast. For a group with no prior public activity, it's a smart way to accelerate familiarity before April 8 arrives.

Fan reaction on X has been building steadily since the first concept photo drop. Longtime Jaejoong fans are cross-posting with rookie group fans, creating an unusual overlap of established fandom energy and fresh debut excitement. That's not something every new group can generate on reveal alone.

Already Booked: KCON Japan 2026

KEYVITUP is already confirmed for KCON JAPAN 2026 on May 8 at Makuhari Messe in Chiba, Japan, per KCON's official 2026 lineup announcement, less than a month after their April 8 debut. Appearing at KCON this early in a group's career signals label confidence. iNKODE isn't letting them warm up slowly. They're being thrown straight into one of the biggest K-pop stages in Japan, a market where Jaejoong personally has one of the most fervent fanbases in the entire industry.

If there's a debut strategy designed to front-load impact, this is it: concept photos, documentary content, self-titled EP, and an international festival booking, all within the first month of existence. KEYVITUP isn't debuting quietly.
