三正工業 Company Profile

"Though invisible, they are essential; small yet powerful," we continue to produce hydraulic and pneumatic equipment, the unsung heroes of the industrial world.

Sanjō Kōgyō Co., Ltd. has been manufacturing hydraulic and pneumatic equipment for over 50 years since its establishment in 1958. In the field of "monozukuri" (manufacturing), there are many companies with a craftsman spirit, which means that while they have the technology, many do not provide adequate proposals or management. On the other hand, many customers are seeking "manufacturing + α." At Sanjō Kōgyō, we comprehensively engage with our clients from order receipt to manufacturing, delivery, and aftercare, dividing our operations into manufacturing and management departments. Sanjō Kōgyō marks the highest quality not only in products but also in services. To respond to the wide-ranging and high-level requests from our business partners, Sanjō Kōgyō has 100 manufacturing partner companies across Japan. We have numerous partnerships with excellent companies in various manufacturing and processing fields, allowing us to mobilize our wisdom and experience to meet even the most complex and challenging requests. We are continuously working to overcome issues such as "cannot be made" and "cannot meet deadlines." Additionally, we are focusing on young new companies with excellent technology across Japan and have established partnership contracts, striving to provide broad support regardless of the area.
