“SEL OCTAGON TOKYO (Cell Octagon Tokyo)” is a club in Roppongi that Avex Entertainment opened in 2019. It features a three-dimensional sound design incorporating ultrasonic waves and a futuristic space created by reflecting 10 lasers onto a mirrored wall. Our corporation is responsible for producing content for membership-based party events. When the floor was transformed into an art space with performances by Japanese rock bands, contemporary dance by contemporary art creation groups, and costumes inspired by flower drums, etc., there was applause in the hall.
