Social Networking Ueda started using Instagram on February 14, 2023, a month after fellow KAT-TUN member Kamenashi and a month before Nakamaru. He is the only one who posted in English in their opening post, in which he shared an image of himself and his dog. Further posts with co-stars, friends and KAT-TUN members, like the one on March 22, KAT-TUN's debut anniversary, have been in Japanese, with some including phrases in English.
Writer Ueda penned his first novel, "Kono koe ga todoku made", based loosely on his life. According to Ueda, he started writing when KAT-TUN's third member had decided to leave, around 2015. He began recording his feelings as a member, before deciding to make it a novel. He had done around 2/3 of the work, when he consulted the agency, who would discourage him from continuing. With the changes in the agency and his own work structure, he thought that he might be able to continue, so he went and consulted the agency again. As he continued writing, now his feelings about the group's disbandment were also included. The main character, Ryu, embodies aspects of Ueda's personality and life, as he mentioned in a comment. With the end of KAT-TUN, the book's characters' many challenges, worries and struggles, shared with friends, reflect Ueda's thoughts on friendship and dreams. He hopes that the book is read by people in group activities around the world, as well as fans and other people who support them. The novel was released on June 27, 2025. Ueda held a talk event in Tokyo (July 1), and handing-over events in Tokyo, Osaka and Aichi (July 2, 3 and 6) to celebrate the release.
