JI BLUE, the collaborative unit formed from members of JO1 and INI, made their debut on YouTube's THE FIRST TAKE channel on June 10, with all 12 members performing together.

The group performed "Keshiki" (Scenery), the official theme song for the Japan national soccer team's 2026 World Cup campaign. JI BLUE was specially assembled as the official ambassador unit for "The Most Beautiful Scenery in 2026," the campaign supporting Japan's soccer efforts.

The lineup includes six JO1 members—Tasuku Yonashiro, Ruki Shiraiwa, Junki Kono, Keigo Sato, Takumi Kawanishi, and Aomi Kinjo—alongside six INI members: Koto Nishi, Shogo Tajima, Taiyume Takatsuka, Isao Goto, Yudai Sano, and Masato Ikezaki.

In their THE FIRST TAKE appearance comment, the group emphasized the song's message: "'Scenery' is an encouraging song meant to push everyone forward. We'd be happy if our 12 members' energy and power come through, and if everyone sings along with us."

The members also shared their excitement about the opportunity. "We never thought all 12 of us would get to appear on THE FIRST TAKE, so we were truly happy," they said. "We were nervous, but we boosted each other's energy during the performance, so we think it became an enjoyable THE FIRST TAKE."

This marks a significant moment for both groups, bringing together popular acts from JO1 and INI for a patriotic performance tied to Japan's soccer campaign. The one-take format of THE FIRST TAKE, which captures live performances without editing, adds to the impact of seeing the full roster perform together.

"Keshiki" released on June 3 and has since become associated with Japan's World Cup preparations. The song's release and THE FIRST TAKE appearance represent a major push for the campaign in the lead-up to the tournament.
