Directed and produced by KOO-KI’s Tatsuhiro Momen, this TV commercial was made for Asahi Solar, a pioneer in solar water heating systems. A sumo wrestler jumps off a roof and dives straight into a bathtub. A shot that would normally require an elaborate setup is rendered realistically yet in a humorous ukiyo-e style using generative AI. In addition to the “East — The Power of the Sun / Blue Sky” version, there is also the “West — Leave It to Us, Peace of Mind / Gold” version.

Exploring a variety of expressive approaches through different techniques, such as digital drawing that looks like pen-and-ink or pencil-and-watercolor illustrations, animation compositing with photorealistic 3D, and creating and compositing animation with analog ink. Outside of reels, I also work on planetarium pieces and other projects using hand-drawn 3D created with VR painting.
