New York Underwear Brand PSD Officially Launches in Japan with Online Store

Custom Produce Co., Ltd. (headquartered in Abiko, Chiba Prefecture) has begun the full-scale rollout of New York underwear brand PSD in Japan. On April 21, 2026, the company opened the official Japanese online store (https://psdu de wea -jp.com/) to accelerate further growth in the Japanese market. Background and Aim: Turning Underwear into Gear for Self-Expression In recent years, Japan’s menswear market has seen growing demand not only for functionality, but also for items that reflect personal values. Among Gen Z and millennials in particular, the idea of completing one’s style down to the innerwear, much like sneakers or accessories, has been spreading. Since its founding in 2007, PSD has promoted the idea of making underwear part of culture. Through deep ties with world-class athletes such as NBA players Ja Morant and Jimmy Butler, as well as music and street culture, the brand has gained strong support across the United States. By opening its official Japanese online store, PSD aims to offer fashion- and sports-conscious Japanese consumers a new form of self-expression. Key Features of PSD 1. High functionality trusted by top athletes: PSD’s core product, CORE STANDARD, offers a comfortable fit that supports the thigh muscles even during intense movement. It uses four-way stretch fabric and flatlock stitching to prevent chafing while maintaining high durability. 2. Outstanding breathability and comfort: The front pouch uses micro-mesh material to ensure maximum breathability even in active situations. 3. Diverse collaborations that express individuality: The Spring/Summer 2026 collection features designs that go beyond conventional underwear, including Ja Morant collaboration models, DC Comics Batman designs, and collaborations with rock and punk culture brand BROKEN PROMISES. CORE STANDARD, PSD’s flagship model, is designed with functionality that satisfies top athletes around the world and close attention to comfort in every detail. Spring/Summer 2026 Collection Overview (selected items) The Spring/Summer 2026 collection includes Ja Morant collaboration items, a collaboration collection with BROKEN PROMISES inspired by motorcycle, rock, and punk culture, Batman collaborations popular in Japan, and the Money & Luxury collection featuring bold designs inspired by currencies from around the world.
