Penthouse is a Japanese band formed in the late 2010s around Mike Parvizi and Preston James. Its music blends pop, soul, funk, jazz, and R&B in a groove-oriented style. Vocal harmonies, layered instrumentation, and melodic interplay shape the band’s sound, which moves between smooth, warm passages and brighter hooks while combining modern Japanese band music with city-pop and soul-influenced textures.
In 2026, Penthouse performed "Ichi Ni San" as the opening theme for the fourth season of "Mairimashita! Iruma-kun". The song brought the group’s ensemble sound into anime and reflected the rhythmic detail and harmony-focused approach heard across its catalogue.
