ノースリーブス, commonly stylized as no3b, is a Japanese pop girl group derived from the popular idol group AKB48. Formed in August 2008, the subunit initially consisted of three AKB48 members: Minami Takahashi, Haruna Kojima, and Minami Minegishi, all of whom were prominent figures within the larger group. The name "ノースリーブス" itself is a play on words, reflecting the member's names ('no sleeves' to sounds like 'no three bees', with the 'three' referencing the trio) and also signifying a style emblematic of the fashion-conscious unit.

Their musical style encompasses a mix of upbeat pop tunes, ballads, and electronic dance music, which has garnered them attention beyond the AKB48 fan base. Over the years, ノースリーブス have released a collection of singles and albums that showcase their vocal talents and ability to captivate audiences with catchy hooks and relatable lyrics. Songs like "キリギリス人" and "ペディキュアday" highlight their versatility and commitment to delivering fresh and engaging music. Even after the eventual graduation of the members from AKB48, the legacy of ノースリーブス within the J-pop scene remains influential, celebrated for their contribution to the idol genre and for the distinct charisma each member brought to the ensemble.
