KOO-KI’s Toichi Shirakawa directed and produced this commercial for UHA Gummy Supplement. The music is an arranged recording of Kocchi no Kento’s hit song “Hai Yorokonde,” created specifically for this commercial. The illustrations are newly drawn by Oshushi Muromuki. To achieve a subliminal effect, the production was designed so that the product package appears in every cut. To present it without being intrusive, the team added touches such as well-timed coordination with the music, a pleasing sense of progression, and small playful elements (the gummy pieces) to keep it engaging and prevent it from becoming dull.

A special opening created to commemorate the 30th anniversary of the hugely popular training simulation mode “Success,” produced in collaboration between Konami Digital Entertainment and KOO-KI. It depicts characters who have long battled as rivals now fighting together as teammates on the same Japan national team.

A web commercial produced as part of GUNZE Limited’s 130th anniversary project, marking the company’s 130th year in August 2026. Taking advantage of the fact that some younger viewers may not even be able to read the company name “GUNZE,” the film vividly brings the catchphrase “Unreadable, GUNZE.” to life. The concept was developed by a team centered on KOO-KI’s younger staff, who themselves are among those on the “unreadable” side. KOO-KI’s Tatsushi Yuu, known for his wide range of directing styles, transformed their wildly free-spirited ideas into an entertaining visual piece. In addition to the “Calligraphy” version, the web commercial also includes a “Vision Test” version.

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.
