We invited local citizens and held a sustainable river illumination festival called “Tokyo Hotaru,” with a focus on eco-friendly “Inori-boshi®” LED lights. “Inori-boshi®” is a solar powered device that lights up when placed in water. Its small body is an encapsulation of cutting edge “efficient/solar/battery” technologies, with deep considerations for the environment. With the cooperation of local citizens, we released 10,000 “Inori-boshi®” into the rivers of Tokyo, which became the symbol of coexisting nature and technology.

We offered local citizens the chance to experience the coexistence of nature and the city, and with their cooperation the event ended in great success. In order to realize Tokyo’s goal of becoming a “beautiful city”, it has been decided that festival will be held once again in 2013.
