City Onsen is an imaginary brand we’re using as a placement at the end of this 10-second ad series (bumper ad? Yes, maybe). We had this concept in mind years ago and recently decided to bring it to life with the help of AI. Just two frames per video, a really simple message: the moment you immerse yourself in hot mineral water and all your burdens fade away, instantly litterally. That’s why we bring hot mineral water to everywhere to proof it. Show not tell.

We want to focus on the character’s deeply satisfied facial expression.

We’re crafting the prompts here, no cuts, just a static camera as a deliberate directorial choice. We used a 3D stylised toon art direction for the videos, realistic enough to feel grounded, yet friendly enough for a young family audience.
