In April 2017, the three organizations started to install the Flower Merry-Go-Round on the roads and at public facilities and event sites in Katsushika-ku (ward). And, since then, Tokyo Metropolitan Nohsan High School, etc have been engaged in the verification test of the flower bed by examining the amount of watering, the concentration of fertilizer and the growth state of three dimensionally-arranged flowers.
With the latest agreement, Panasonic's mist generator will be added to the Flower Merry-Go-Round as a cooling measure so that people can stay in public spaces with comfort in summer. The power supply of the mist generator is not the solar panel of the Flower Merry-Go-Round.
Katsushika Ward aims to install the flower bed at international competition sites such as the sites of the 2020 Tokyo Olympic/Paralympic Games.
