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.
