Tokyo Sangyo Yoshi Co.,Ltd

Tokyo Sangyo Yoshi Co.,Ltd. is a distinguished Specialized Trading Company for Electronic Materials, boasting a proud history and extensive track record that spans over a century. The company’s genesis dates back to the Taisho era, 1919, when its founder, Keiichi Shimanaka, observed the capacitor paper used in imported radios and saw a business opportunity, subsequently establishing "Shimanaka Shokai" to deal in electrical materials. This foresight and entrepreneurial spirit led the company to play a pivotal role in the industry, including undertaking the sole distribution of the first domestically produced capacitor paper. Through these efforts, Tokyo Sangyo Yoshi firmly established its position as a major trading company for electronic component raw materials. The company was formally incorporated in July 1954.

Today, leveraging the technical knowledge and global network cultivated since its founding, the company handles a comprehensive range of products, from materials for electrical and electronic equipment and industrial papers to cutting-edge functional materials. The business is fundamentally structured around the provision of: Electronic Component Materials (such as various separator papers for electrolytic capacitors and high-density pressboards); Functional Films and Materials (including various films, non-woven fabrics, glass papers, fluorine-based coating agents, and other specialized items); and Machinery and Equipment (such as element winding machines for capacitors, screen printing machines, and coating machine modifications) necessary for using these materials.

A key differentiator for Tokyo Sangyo Yoshi is its commitment to moving beyond simple buy-and-sell operations by providing advanced Converting (Contract Processing) Services. In collaboration with its subsidiaries and a network of specialized processing companies both domestically and internationally, the company offers secondary processing services such as slitting, cutting, laminating, punching, impregnating/coating, and assembly. By offering integrated support—from material procurement and processing to equipment installation—the company serves as a multi-faceted partner, actively supporting the technological development and production activities of component manufacturers.

The company's core strengths are the "Trustworthiness" built over many years as an intermediary between material suppliers and component manufacturers, and the "Spirit of Challenge" inherited from its founder, continually striving to pioneer new business opportunities. The headquarters is conveniently located at Nihonbashi Nikkeidori Building 7F, 4-6-7 Nihonbashi Honcho, Chuo-ku, Tokyo (Postal Code: 103-0021). The company is led by President and Representative Director Akihiro Mori, is capitalized at 54 million yen, and employs 55 people. Furthermore, with subsidiaries in Taiwan and Malaysia (TOKYO SANGYO YOSHI MALAYSIA SDN.BHD.), the company has established a global sales network, continually contributing to the advancement of the electronics industry. The company is dedicated to being a specialized trading firm that perpetually creates "true value" to meet society's evolving demands.
