Benjazzy and Bonbero’s B2B Was Not Made in 17 Days: The 156-Day Record

Benjazzy and Bonbero did not make B2B in the 17 days after their BATTLE SUMMIT III loss. That reading is tempting because the album arrived on August 28, 2026, 17 days after the tournament. The documented dates do not support it.

On March 25, Bonbero said that he and Benjazzy had been discussing an album. By August 7, he described the project as underway, rap-heavy and completely different from his preceding solo album, HideAway. The full release followed 156 days after his first public statement.

The tournament remains part of the story, but it is not the origin. The sharper question is how a partnership that already crossed songs and stages became an eight-track record with both names on the cover.

Six Facts First

The project’s official TuneCore distribution record supplies the release date, sequence, writing, production and engineering credits. Spincoaster’s release report — Japanese documents the artwork credit to ONI.

The Evidence Starts on March 25

In a Red Bull RASEN interview published March 25 — Japanese, Bonbero discussed two albums he hoped to release in 2026. One was a solo record. The other was an album he said he had been discussing with “Ben-san”—Benjazzy.

The evidence became more specific on August 7. In a Rolling Stone Japan interview republished by Mynavi News — Japanese, Bonbero called the work with Benjazzy “very rap.” He said he was rapping more than usual and described the feel as completely different from HideAway. He also said his approach to writing lyrics had changed.

Both statements came before BATTLE SUMMIT III. They turn the tournament from an origin story into a late chapter in an existing project.

Two Musical Entrances: “R2R” and “Wagamama”

“R2R,” produced by ascii, arrived with the album announcement on August 12. THE MAGAZINE’s same-day report — Japanese describes a UK garage and two-step beat, with the rappers testing their skills against each other. It was the rollout’s first advance single.

Before the album arrived, “Wagamama” offered a different entrance. THE MAGAZINE’s release report — Japanese highlights the pair’s high-speed delivery. LiFTED’s track review hears Bonbero begin over a sparse Chaki Zulu beat. The production fills out, Benjazzy enters with a hyperactive style, and the two eventually trade bars.

The distinction matters. “R2R” uses two-step momentum; “Wagamama” changes beat density and vocal pressure. Together, they resist the claim that six producers created one interchangeable showcase of technical rap.

Two album cuts widen that picture without requiring a line-by-line translation. On “KINGING,” separate verses repeatedly return to a collective first-person refrain. The song moves from individual memories of deprivation and risk to a shared B2B identity. The licensed Japanese lyric display on AWA makes that shift visible.

“Way Back” uses the pair differently. One verse moves from past nightlife to the routines of raising two sons. Another looks outward through travel, hotels and unfinished ambitions. The licensed AWA lyric page documents those contrasting scenes. Shared billing gives two career stages the same refrain and sequence; it does not make the rappers interchangeable.

The Eight-Track Map

“SUDORI” is the spelling used by the English distribution page; 素通り is the Japanese title. Keeping both is more accurate than inventing an English translation.

The first three tracks contain only Benjazzy and Bonbero. Two guests arrive together on track four. The album then returns to the core pair for three songs before ending with another two-guest record. All four featured rappers are concentrated at the midpoint and endpoint.

Only two of the six producers appear twice. Chaki Zulu handles “Wagamama” and the four-rapper finale, “4 Walls.” ascii produces “SANZAN” and the advance single “R2R.” The repeat producers sit at public or structural turning points; the other four tracks change hands.

That reading comes from credits and sequence. The artists have not publicly explained the design in those terms. Even so, the pattern shows recurring positions rather than eight unrelated sessions.

The 156-Day Record

BATTLE SUMMIT III was a team-format MC battle at K Arena Yokohama. HIPHOPCs’ Japanese on-site results report records OZworld and CHICO CARLITO winning the tournament. They defeated Benjazzy and Bonbero in the quarterfinals.

The following day, THE MAGAZINE’s announcement fixed the album date and advance single. It did not disclose recording dates, when the sequence was finalized, or any change caused by the tournament result. The final track information in this article comes from the official distribution credits.

The documented sequence supports one conclusion: B2B was not created from scratch after the defeat. The joint-album plan was public 139 days before the tournament and described as active four days before it. August 12 was an announcement, not a sudden origin.

The Partnership Predates the Album

Before B2B, the rappers had shared BAD HOP’s “B2B feat. Benjazzy & Bonbero” and Bonbero’s “For A Reason feat. Benjazzy.” Benjazzy’s 2025 album UNTIL added “WWW feat. Bonbero.” Its official TuneCore credits identify Chaki Zulu as producer. The Benjazzy–Bonbero–Chaki Zulu combination therefore predates “Wagamama” and “4 Walls.”

The pair also performed “B2B” together at POP YOURS 2024, according to the festival’s official report published by Spincoaster — Japanese. In 2026, they added a team battle and joint album to that history.

This context matters for readers outside Japan. B2B was not the pair’s first meeting. It formalized a relationship that had already existed across individual songs, live performance and battle rap.

Benjazzy’s route runs through BAD HOP and Kawasaki; Bonbero is from Yachiyo, Chiba. Space Shower Music’s official release profile — Japanese documents those distinct origins. HIPHOPCs maps Benjazzy’s side through its English Kawasaki and Yokohama Rap Atlas and T-Pablow profile.

Calling B2B a joint album does not erase those routes. It means the two names now share the sequence, rollout and title—not just a verse. A tournament fixed one result on August 11. The album fixed a longer relationship in a form that outlives it.
