YAMAUCHI Co., Ltd. (Headquarters: Takamatsu City, Kagawa Prefecture / Representative Director: Masashi Okamoto, hereinafter JOYFIT24), which operates the fitness gym "JOYFIT24," is collaborating with AI model Inc. (Headquarters: Minato-ku, Tokyo / President & CEO: Daiki Taniguchi, hereinafter AI model) to evolve their exclusive AI character "JOY MACHINES," created using the latest generative AI technology, into its next generation. A "New Team Name Voting Campaign" will be held on official X (formerly Twitter) from Wednesday, July 1st, 2026, to Monday, July 20th, 2026, where users will vote to decide the new team name. This is a user-participation project that announces their new beginning (update), breaking free from the inorganic framework of "training equipment" that merely provides functional instruction, and transforming into a partner that resonates with each user's heart. ◾️What are JOY MACHINES? JOY MACHINES are exclusive characters anthropomorphized with the latest AI, based on the characteristics of actual training machines. They are navigators that intuitively convey correct form and how to use machines, and partners that alleviate beginners' anxieties. They were born to gently support all users in continuing their daily training and to be a strong ally in "becoming the body they desire." ◾️The Path to Evolution Revealed in the Official X Series "JOY MACHINES Voting Secret Story" Prior to the launch of this project, a 5-part manga depicting their inner struggles and resolve was released on official X (formerly Twitter) as "JOY MACHINES Voting Secret Story." It unfolds the drama leading up to the vote for the new team name. 【Official X】 https://x.com/JOYFIT_official ・Part 1 "Birth": Users' aspirations challenging limits imbue machines with soul ・Part 2 "Doubt": Being correct alone isn't enough.
