As the second part of the “Rediscovering the Sumida River: A Boat and Waterfront Project” jointly administered by Kadokawa Corporation and Sumida Ward in Tokyo, a “Mirror Ball Car,” a work of art created by Tatsu Nishino featuring a rotating car covered in mirror chips and illuminated by lights, was suspended from a crane over the Sumida River. To celebrate the installation of this artwork, an open-air disco was also set up, with music provided by DJ TAICHI MASTER, allowing young and old alike to dance the night away.
