J-Star Holding Co., Ltd. is a leader in innovative carbon fiber and advanced composite solutions. With decades of experience in composite materials, J-Star applies deep technical expertise to design, engineer, and manufacture a wide range of lightweight, high-performance carbon composite products — from key structural components for sports equipment and electric bicycles to automotive and healthcare applications.
J-Star’s core strengths lie in its proprietary resin systems, research and development capabilities, and product design. Through its dedicated R&D center for resin and raw material research, the company customizes and invents formulations that meet the highest standards of quality, durability, safety, and sustainability.
Through its subsidiary YMA Corp, J-Star integrates the end-to-end process from raw material development to the production of retail-ready products. YMA has played a pivotal role in the success of many of the world’s premier racket and bicycle brands, contributing to victories in the Olympics, Grand Slams, World Championships, and Tour de France events.
Building on this legacy, J-Star has entered the rapidly growing pickleball market with YMA Paddles, applying its advanced carbon composite technologies to the design and manufacture of the company's first line of company-owned high-performance pickleball paddles. The company has also partnered with QO Bikes, a premium cycling components brand co-founded with industry veterans, and is scaling the LITZMO brand, a line of high-performance carbon fiber e-bikes that leverage J-Star’s advanced composite technologies and manufacturing know-how.
With headquarters and R&D operations in Taiwan and a global manufacturing and assembly footprint serving customers worldwide, J-Star is a true end-to-end carbon fiber and composite solutions expert.
