From ancient times, the Japanese have lived with the wisdom and tools to enjoy the cool breeze, such as a bamboo blind that allows cool breezes to escape from the sun, wind chimes that provide a cool feeling to the eyes and ears, and a fan that creates a breeze around you in any place, even if it is small. There are also many waka poems about the wind, and there is a culture that has spent time facing the wind both physically and mentally. Today, with the advancement of science and technology, it is possible to stay cool efficiently and effectively, but at the same time, the problem of global warming is becoming difficult to overlook. We decided to carry out this project because we want children to discover and create a "cool summer" that is sustainable, friendly to the earth, and comfortable using the sense of beauty that Japan has always had with its five senses.
