Nagoya's own local girl-idol song and dance group OS☆U ("oh ess you") has been bringing their high-energy cheer to the Walkathon annually since 2015. They'll be back again this year, too, with a performance and a special message of support in the online portion of the event.

Also a part of the online program are the rising stars in five-man vocal and dance unit Cool-X, who made their Walkathon debut at last year's event. This time they're performing "My Friend," their chart-topping new song that also features Nagoya-based hip-hop star Seamo.
