Shuetsu Sato, a 72-year-old security guard working the overnight shift at Tokyo’s Shinjuku train station, has gained recognition as one of Japan’s most sought-after graphic designers through his unconventional medium: duct tape. What began in 2004 as a practical solution to help travelers navigate the complex station during renovations has evolved into a distinctive artistic style known as “Shuetsu-tai.”

Sato was initially asked to create signage to guide commuters through the station’s maze of train lines and exits. Using only duct tape, he crafted clear, rounded-edged lettering intended to soothe the frustration often felt by crowded commuters. His work quickly impressed station officials, leading to more requests and eventually catching the attention of design experts across Japan.

Despite no formal art training, Sato’s unique duct tape typography has drawn commissions from major corporations, including Nintendo, Suntory, and, most recently, Nike. He collaborated on a logo for Nike’s new physical store in the Shinjuku shopping district, which opened last month. Shun Sasaki, a graphic designer working with Nike, praised Sato’s craftsmanship and passion, describing his lettering as “cool” and “powerful” and noting Sato’s “incredible passion” and drive to create.

Sato’s dedication to his craft remains rooted in his day job; he often becomes so absorbed in making signs that he forgets to eat or sleep. Interestingly, he does not charge fixed fees for his work. Instead, he requests only meals during working sessions, reimbursement for transportation costs, and the freedom to use duct tape exclusively. His modest compensation has sometimes come in the form of small tokens such as shampoo sets or socks, reflecting his personal motivation rather than financial gain.

In 2025, Sato received the Japan Sign Design Association’s platinum award, honoring his distinctive typography and contributions to public design. The recognition cemented his reputation and further fueled demand for his duct tape signage.

What started as a practical approach to aid commuters navigating a busy train station has transformed Shuetsu Sato from a security guard into a celebrated designer whose minimalist, tactile style resonates with audiences and clients nationwide. His work continues to bridge the worlds of functionality and art, grounded in simplicity and human connection.
