エスピー工研 Company Profile

Responding with trust and technology, design and manufacturing of metal products.

Our company was founded in the late Meiji period. After inheriting the legacy of Sugiyama Iron Works and starting as a sole proprietorship, we established Hirata Agricultural Machinery Manufacturing Co., Ltd. in October 1940 (Showa 15). After the war, we manufactured and sold agricultural tools, which were necessary for social reconstruction. However, as times changed, so did our products, and we have been able to meet the needs of society for over 70 years, thanks to the support of everyone. In recent years, we have incorporated various materials into our manufacturing and sales, but we have set the improvement of customer satisfaction as a key goal, and all our employees are dedicated to manufacturing.
