In addition to designing a logo to commemorate the 90th anniversary of Itabashi Ward's ward system, we created the "Itabashi Ward 90th Anniversary Commemorative Magazine," which introduces the ward's activities, and the "Itabashi Ward 90th Anniversary Leaflet," a summary version of the magazine, and designed displays for commemorative events. We also collected messages from Itabashi residents looking back on the history of Itabashi Ward and expressing their wishes for the future, and asked them to write messages for the next 10 years. In addition, a workshop was organized in which participants were asked to create a work of art using colored paper in the shape of Itabashi Ward's neighborhoods, inspired by the shapes of the paper. The works created by the residents were made into a book.
