103DESIGN (one-o-three design) is a design studio based in Asakusa, Tokyo run by a graphic designer, Aya Watanabe. We value the power of printed matter and create a gentle and easily understandable design for the audience. In addition to advertising design, we produce original stationery made of paper.
Our advertising design work is not allowed to be publicly put on a website because of copyrights and portrait rights are on the Portfolio page. In case you would like to see them, please contact us via the contact form.
