Sustainability Weeks Official Logo

SW logo Hokkaido University called for a logo design of Sustainability Weeks in spring 2012. As a result, 197 creative designs were gathered from high school students to elderly people, and from amatures to professionals. The executive committee of Sustainability Weeks 2012 chose the distinctive piece of work designed by Mr. Soichi Yamaguchi, who lives in Tokyo.

A Concept of Design

This design is based on the concept of “sustainable flow of the times”. The fluidity in the transition of rigid to organic expresses historical progression towards the future. The harmonious and gradual change in color indicates plurality and diversity in nature, humanity, culture, and society. Looking like a brilliant star or a flower in full bloom from a distance, it symbolizes the resplendent beauty of life.
