ONE OR EIGHT is an eight-member boy group composed entirely of Japanese members: MIZUKI, NEO, REIA, RYOTA, SOUMA, TAKERU, TSUBASA, and YUGA. Their name, ONE OR EIGHT, is derived from the Japanese idiom “Ichika Bachika”—meaning “all or nothing”—reflecting the group’s fearless ambition and commitment to chasing their dreams. With the tagline “BET ON YOURSELF,” the group embodies a spirit of self-belief, camaraderie, and risk-taking as they strive to make their mark on the world. They officially debuted on August 16, 2024, with the single “Don’t Tell Nobody,” produced by Ryan Tedder (Taylor Swift, Adele, Jonas Brothers) and David Stewart (BTS). The track quickly rose to prominence, reaching No. 1 on the Billboard Japan Heatseekers Songs chart. Further cementing their international appeal, ONE OR EIGHT released “KAWASAKI (with Big Sean)” on December 6, 2024—charting No. 5 on the U.S. iTunes Hip-Hop/Rap Songs chart. They were also named one of Nikkei Entertainment’s “100 Breakout Stars to Watch,” and took home the “Upcoming Dance & Vocal Group” award at the MTV VMAJ 2025, solidifying their status as rising icons in the global music scene.
