Introduction

A3! (pronounced “A-three”) is a Japanese idol group that debuted under the management of Stardust Promotion in 2015. The group is noted for its energetic performances, colorful costumes, and strong emphasis on teamwork.

This article presents a comprehensive overview of the discography of A3!, including studio albums, mini‑albums, singles, compilations, and other releases, as well as a discussion of chart performance, certifications, and notable collaborations.

Formation and Early Years
