@onefive delivered a high-energy performance at EX THEATER ROPPONGI on June 6, drawing a packed crowd of devoted fans to their "@onefive LIVE 2026 'SAKURAIZATION'" concert. The show marked a pivotal moment in the group's evolution as they officially launch their "SAKURAIZATION" project—a creative push toward their 2027 goal of performing at Tokyo's iconic Budokan.

The setlist showcased @onefive's range across multiple musical styles. Opening with "♡革命少女S♡," a track that samples "Heart no Chikyuu" from Sakura Gakuin (the training group all four members passed through), the performance balanced cuteness and power throughout the night. The group moved between playful tracks like "KAWAII KAIWAI" and harder-hitting numbers such as "KIBIDANGO," which pairs hip-hop beats with a Japanese folk melody to signal their identity beyond just cute aesthetics.

A standout moment came during the premiere of "無敵☆アタシモード prod.☆Taku Takahashi," a new song created by legendary producer Taku Takahashi. The track samples BABYMETAL's "ド・キ・ド・キ☆モーニング" and blends chiptune, hyperpop, and rock elements—a combination member MOMO described as "BABYMETAL × Perfume = @onefive."

Between songs, members opened up about their Budokan ambitions. KANO read from a prepared letter, acknowledging the difficulty ahead while expressing unwavering commitment. "The path to Budokan isn't easy and honestly, I'm uncertain we can achieve it," she said. "But because we've risked everything, I don't want to stop here. Every moment matters because time is finite—let's see the Budokan view together next spring."

GUMI shared how the "SAKURAIZATION" project represents acceptance and growth. "When @onefive first started, we didn't want to be seen as Sakura Gakuin kids," she explained. "Now that @onefive is recognized in our own right, we can finally embrace where we came from." She urged fans to stick with them: "Things haven't always gone smoothly, and I know it's been tough for everyone. But we'll keep working to show you something better."

With the sold-out Tokyo show and an upcoming Osaka date, @onefive has demonstrated they're ready for bigger stages. Their Budokan dream no longer feels like wishful thinking—it feels inevitable.
