cosmosy

cosmosy is a Japanese four-member girl group consisting of himesha, de_hana, kamión, and a'mei. Their name, derived from “COSMOS of Youth,” symbolizes endless possibility and an ever-expanding universe. cosmosy debuted in 2025 with “Lucky=One,” following the viral pre-debut track “zigy=zigy,” whose music video surpassed 10 million views within two weeks. Their debut year quickly gained global traction, with “Lucky=One” ranking on the 2025 Year-End Genius Korea Chart (Top K-Japanese Songs) and the group being named one of Google’s Year in Search 2025 Global Breakout K-Pop Debuts. They continued to expand their sonic and conceptual identity through releases like “BabyDon’tCry=BreakingTheLove” and their 1st EP “the a(e)nd,” building a narrative-driven universe that blends emotional storytelling with genre-crossing production. In partnership with NTT docomo Studio & Live and Sony Music Entertainment Korea, cosmosy is steadily establishing a global presence — delivering immersive music and performances that move as four distinct individuals within one universe. Now entering the “~ of the world ~” era, “Physics ~ 物理的な ~” reimagines love as a force of gravity through sleek house grooves, while the pre-release single “Chance ~ switch on ~” captures the quiet thrill of a moment that could change everything. Together, these releases set the stage for cosmosy’s 2nd EP “~ of the world ~.”
