KDDI's new headquarters moved to Takanawa Gateway in June 2025. We were in charge of the direction and video production for the Sony Crystal LED installed in the entrance. We reconstructed it as a giant device that allows visitors to experience KDDI's concept of "connecting." We depicted the grand cycle of time as a universal and symbolic animation, and expressed the "time" that continuously connects everything through generative clock art. Furthermore, by seamlessly connecting the two, we designed an experience in which an **"infinite chain"** rises in the entrance.
