Ryokuoushoku Shakai, often shortened to Ryokushaka, is a premier 4-piece Japanese pop-rock band that emerged from Aichi Prefecture in 2012. The group's sound identity is built upon the exceptional vocal range of Haruko Nagaya, whose 'belting' technique and clear projection have become a benchmark in modern J-pop.

Musically, they are a rare example of a band where every member contributes to songwriting, resulting in a diverse catalog that bridges the gap between traditional guitar-based rock and piano-driven pop. Their career arc saw a steady rise from the 'Senkou Riot' festival to becoming a household name through major anime tie-ins and commercial placements. Culturally, they occupy a space similar to Official Hige Dandism, emphasizing high-level musicianship within a mainstream pop framework. Critical consensus highlights their technical proficiency, particularly the interplay between the piano and bass, which adds a layer of sophistication often missing from standard idol-driven pop. They are viewed as a bridge between the 'band boom' of the 2010s and the more eclectic, genre-fluid J-pop landscape of the 2020s.
