"Kiccoro," the mascot characters of Expo 2005 Aich Japan. The fourth event was held with live coverage on the FM radio on September 19th. Each of the three groups of participants started from Shirakawa Park, Tsurumai Park and Meijou Park, and they cleaned up the way towards the same goal at the TV tower in Sakae. In the hot weather, the children raced to pick up the trashes and encouraged others to follow. The flower seeds were given to the participants in the hope that each one of merry minds to care about the Earth would keep growing even after the Expo and bring forth a big flower. In the autumn sun, a message from a cuban child shone on the collected garbage bags - "Hope for the world!"
