As the first initiative, a participatory project "Let's Decide Together! Commemorative T-shirt Design Voting" will begin on March 26th using the official LINE account for the event. This is a collaborative project with the Fukuoka Marathon Executive Committee and the official wear partner Xebio Co., Ltd.

**■ "Let's Decide Together! Commemorative T-shirt Design Voting" Project Overview** In this project, users will select and vote for one design they like from three design candidates presented on the official LINE account for the event.
