Reiju Sato (b. 2002) is a Japan-based fashion designer.

He graduated from Bunka Fashion College in 2024, where he received the Grand Prix in an internal competition, and his work was exhibited at Première Vision Paris. In 2025, he won 3rd place at the Asia Pacific Emerging Designer Fashion Contest.

Drawing inspiration from objects left behind by the passage of time, his practice centers on deconstructing discarded T-shirts and reconstructing them into new materials. Working primarily with natural textiles treated through rust dyeing and charcoal dyeing, he explores the intersection where beauty and decay converge.

He is currently developing works in preparation for the launch of his brand hypnotique sense for the Fall/Winter 2027 season. The collection concept is “ruinphilia.”
