Narumiya Characters (ナルミヤキャラクターズ) are a collection of mascot characters created by Narumiya International for its junior fashion brands, including Angel Blue and Mezzo Piano. Introduced primarily during the 1990s, these colorful mascots—such as the blue alien Nakamura-kun and the pink bear Berrie-chan—feature playful, expressive designs that have become closely associated with Japanese Y2K fashion. Originally appearing on clothing, stationery, and accessories, the characters remain popular as nostalgic symbols of the brand's distinctive aesthetic and continue to be featured on merchandise and collaborations.
