In 2022, he led the year-long development of hoyaONE, a private-label contact lens brand from HOYA EyeCity. His work encompassed research and interviews with key stakeholders, defining the brand philosophy, naming, package design, promotional materials, and internal brand communication, culminating in the brand's launch.

As the collage artist ONEILL, he presented collaborative artworks with photographer Osamu Nagahama in 2019. Since 2024, he has created collages from sketches and production materials from his own branding and visual identity projects, reconstructing the thoughts and memories behind the finished designs and making the design process visible through art. In 2026, he began expanding his practice into original brand art, combining narrative and design to envision fictional brands inspired by questions and challenges in contemporary society.
In 1998, the New York annual GRAPHIS DESIGN introduced him as one of twelve designers from around the world.
