Nihon Tsusan Co., Ltd.

Nihon Tsusan Co., Ltd. (日本通酸株式会社) is a Japanese general trading company (総合商社) headquartered in Sakai, Osaka, with a corporate history dating back to the Taisho era. According to its official website, the company was founded in Taisho 13 (1924), making it a long-established firm approaching its centennial. Despite its long history, the company positions itself as operating at the forefront of industry, supplying products and services tied to welding technology and industrial materials. The company's core identity is built around welding. Its homepage describes Nihon Tsusan as a general trading company that "knows welding and proposes" solutions, delivering welding machines, welding materials, and a wide range of related items just-in-time. Its product lineup spans industrial gases, welding equipment and robot systems, welding consumables, labor-saving machinery and tools, and home appliances and disaster-prevention equipment. A featured product highlighted on the site is the "Space Arm." Nihon Tsusan serves industrial customers in Japan, acting as an intermediary that combines product supply with technical proposals. The company emphasizes the value of human expertise in its sales approach, noting that even as artificial intelligence advances, the core of its work remains people, because making proposals that go "one step further" requires the experience of a trading company. Its stated mission is to support industry by providing the necessary goods and information. The company is led by Representative Director Masakazu Yoshizawa (吉澤 雅一), who has spoken about the firm's long history and its commitment to continuous change. In his greeting, he notes that although Nihon Tsusan is a long-established company about to join the ranks of centenarian firms, the products and work it handles are often at the cutting edge of the times, making it an "old yet new" company. He attributes its ability to work in advanced fields despite its long history to the company's constant evolution and accumulation of knowledge suited to changing customer needs. Nihon Tsusan operates through a network of sales offices and affiliated companies, though specific details of these locations are not provided in the available evidence. The company renewed its website in September 2018. As a private, unlisted company, it does not disclose financial information publicly in the sources reviewed.
