Are We Still Just "Machines"? [JOYFIT24] Exclusive Character Born from Generative AI Evolves. New Team Name to be Decided by User Vote! Starting July 1st (Wed)

YAMAUCHI Corporation (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 / Representative Director President: 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 July 1st, 2026 (Wed) to July 20th, 2026 (Mon, holiday) to decide the new team name through user votes.

This is a user participation project to announce their new beginning (update), where they will break free from the inorganic framework of "training equipment" that merely provides functional instruction and be reborn as partners who empathize with each user's heart.

What are JOY MACHINES? JOY MACHINES are exclusive characters anthropomorphized with the latest AI, based on the features of actual training machines.

They are navigators who intuitively convey correct form and how to use machines, and partners who alleviate the anxieties of beginners. They were born to gently support all users so they can continue their daily training, acting as a strong ally to "become the body they desire."

◾️ The Path to Evolution Revealed in the Official X Series "JOY MACHINES Voting Secret Story" Leading up 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.

● Episode 1 "Birth": The aspirations of users challenging their limits imbue the machines with soul.

● Episode 2 "Doubt": Being correct alone isn't enough. Realizing a mismatch in roles.

● Episode 3 "Resonance": Evolving from instructors to companions.

● Episode 4 "Discomfort": Feeling a sense of unease about their existence while supporting users.

● Episode 5 "Naming": Deciding the new team name together with users.

Three Candidate Team Names Weaving a New Future The candidate team names for users to choose from represent three directions for their evolution.

【Option A】JOYON "JOY" (joy) + "ON" (operation, switch). Supporting the joy of training constantly "ON" 24 hours a day!

【Option B】SYNCER "SYNC" (synchronization, alignment) + "evolution" + "-er" (one who does). A being that synchronizes with your heartbeat, pulse, movements, and even the desire to "change," running alongside you towards an unseen evolution.

【Option C】FITUS "FIT" (fitness, adaptation) + "US" (us). Users and AI characters become one team (US), enhancing each other and surpassing ideals, becoming the best team.
