Sustainability Weeks

What is Sustainability Weeks?

Sustainability Weeks (SW) is an annual campaign hosted by Hokkaido University since 2007. During the event, several thousands of researchers, educators, students, and citizens from Japan and beyond gather at the university to share and discuss the latest knowledge concerning sustainability and to identify the next actions to take towards a better future.

The first such session was organized in 2007, and it has since been held every year with the involvement of the entire university. The events held during SW cover various issues and almost all the academic disciplines relevant to the discussion of a sustainable society.

SW Official Logo

The logo was designed based on the concept “sustainable march of the times”. The fluidity in the transition of rigid to organic expresses a historical progression with succession toward the future. A 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.

Sustainability Weeks Official 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 amateurs 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.
