'Wear Your Life.' - New York's Self-Expression Underwear 'PSD', a Favorite of NBA Stars, Makes Full-Scale Japan Debut! Official Online Store is Now Open.

Custom Produce Co., Ltd. (Headquarters: Abiko, Chiba) has started the full-scale rollout in Japan of the New York-based underwear brand 'PSD'. On April 21, 2026, the company opened its official Japanese online store (https://psdunderwear-jp.com/) to accelerate further growth in the Japanese market.

Background and Goal: Transforming Underwear into 'Gear for Self-Expression'

In recent years, the Japanese men's fashion market has seen a growing demand for items that reflect one's values, not just functionality. Particularly among Gen Z and Millennials, a value system is spreading where style is completed down to the innerwear, much like with sneakers and accessories.

Since its founding in 2007, PSD has upheld the philosophy of 'making underwear a part of culture.' Through deep connections with world-class top athletes like NBA players Ja Morant and Jimmy Butler, as well as music and street culture, the brand has gained immense support across the United States. By opening the official Japanese online store, we propose a new form of 'self-expression' to fashion and sports-savvy users in Japan.
