About KOGYARU
Launched on April 1, 2023, KOGYARU serves as the sister media to Japan’s iconic “gal” magazine, ‘egg,’ focusing on elementary school gal models. Operating primarily through its web-based SNS presence, KOGYARU has rapidly amassed over 500,000 Instagram followers in just under two years. The name “KOGYARU” is a playful portmanteau of the 90s slang “kogal” and “kodomo gal” (child gal), chosen to resonate internationally as “GYARU” gains global recognition.
Beyond fashion modeling, KOGYARU expanded into the music scene, debuting as artists with their song “SHIRANKEDO” in December 2023. They now perform live across Japan, spearheading the next generation of gal culture through diverse activities. “It’s truly inspiring to see how KOGYARU empowers young girls to express themselves through fashion and music,” one fan might exclaim, highlighting the brand’s profound impact.
