Tech Connect's AI-built game wins Aeon Mall prize

Tech Connect's AI-built game wins Aeon Mall prize

3 Key Points

  1. What happened

    Shinji Mizuno, head of Tech Connect, created the interactive signage game 'Higashimikawa Dai-Shukakusai' alone using generative AI 'vibe coding,' despite no game development experience. It won the top prize and Audience Award among all 12 groups at the first Aeon Mall Toyokawa contest.

  2. Why it matters

    The win shows that a solo creator with no game development background can complete a prize-winning interactive experience by working in dialogue with generative AI.

  3. What to watch

    The game runs daily until the 27th from 1–2 p.m. at Aeon Mall Toyokawa's central park. Mizuno aims to expand into renting out his games and creating content for AR glasses and other new devices.

WHO IT HITSIndependent creators and non-technical professionals — such as writers, hobbyists, and office workers — now have a concrete example that generative AI 'vibe coding' can carry a solo project from zero experience to a public prize. Mall and retail event organizers may take note that an individual, not a studio, can deliver an award-winning interactive installation.

Context & Analysis

Mizuno's day job is at a water quality inspection institution in Toyoshima City. During the COVID-19 pandemic, he decided he wanted to make a living under his own name and started writing articles about VR and AR as a writer. That was his turning point. He says he found the process of his own images taking shape to be extremely interesting and began making his own works. The prize-winning game came out of that personal trajectory, not a studio pipeline. The interactive signage contest, held in June this year, drew all 12 groups including individuals and high school students. Mizuno's entry was the one that took both the top prize and the Audience Award. The work itself is designed not to end at play: the crops caught in the game lead to rankings, production areas, recipe suggestions, and specific sales floors inside the mall. Mizuno says he wants families to get excited at the dinner table saying 'that was fun.' He also struggled to balance visual presentation with smooth operation, and even introduced a new AI model right up until the day before the event to get it finished. The stakes for this kind of solo AI-assisted production likely hinge on whether the finished piece holds up in public daily use, and on whether Mizuno can carry the same approach into the rental and AR glasses projects he says he wants to try next.

FAQ
What is 'vibe coding'?
It is a development approach where the creator advances the work by conversing with generative AI. Mizuno used it to complete the game alone despite having no game development experience.
What is the game about?
It is a body-motion game where players stand before a 400-inch screen and move to catch 9 local Higashimikawa agricultural products falling from above. The screen then shows rankings, production areas, recipe suggestions, and in-mall store locations where the items can be bought.
Where and when can I play it?
It is showing at Aeon Mall Toyokawa's central park on the second floor in Shirakawa-cho, Toyokawa City, and can be played daily from 1–2 p.m. until the 27th.
