Masami

Masami (마사미), born Akiba Masami (秋葉正美), is the Japanese rapper in ALL(H)OURS, the seven-member boy group launched by EDEN Entertainment. He debuted with the team on January 10, 2024 through All Ours, immediately giving the lineup a sharper rap edge and a cleaner bridge into the Japanese market.

Masami's role inside ALL(H)OURS is not subtle. The group's music leans on pressure, speed, and attack, and his delivery helps lock that structure into place. As the only Japanese member, he also gives the team a distinct identity point that matters more as the catalog gets deeper and the group's international profile keeps widening.

That catalog now runs from All Ours and Witness in 2024 through Crisis, Phantom, and 2026's No Doubt. Like several young member pages on HITKULTR, Masami's verified public footprint is still anchored to group channels rather than a standalone personal stack, but the discography and official ALL(H)OURS platform already make the page materially stronger than a debut-era stub.

Masami is the Japanese rapper in ALL(H)OURS, the seven-member boy group under EDEN Entertainment. Born Akiba Masami on April 14, 2005, he debuted with the group on January 10, 2024 and has appeared on every official ALL(H)OURS release so far.
Is Masami the Japanese member of ALL(H)OURS?
Yes. Masami is the only Japanese member in ALL(H)OURS, which gives him a distinct role inside the group's public identity as the team grows beyond its Korea-first debut phase. That position also makes him one of the clearest cross-market bridges in the lineup.
What is Masami's role in ALL(H)OURS?
Masami is best understood as a rapper whose energy helps define ALL(H)OURS' fast, hard-edged performance style. The group's songs rely on momentum and aggressive transitions, and his tone gives that structure extra bite instead of softening it.
What albums has Masami released with ALL(H)OURS?
Masami's current official run with ALL(H)OURS includes All Ours, Witness, Crisis, Phantom, and No Doubt. That full-sequence presence matters because it shows continuity across the group's entire catalog rather than a page built around a single rookie release.
Does Masami have verified official social media?
The verified public stack currently runs through ALL(H)OURS' official channels rather than a clearly confirmed standalone Masami account. That includes the group's Instagram, X, TikTok, YouTube, Spotify artist page, and official platform site, which are the safest first-party surfaces for updates and media.
