Business Contents

Working proudly as Japanese in the world of manufacturing.
Kubotec values integrity production by “handmade”. We handle all processes from orders to design, manufacture, shipping, after-sales follow-up, and complete products carefully with reliable technology. We pursue high “quality” from fine details such as tightening one screw. Products such as power supply equipment and control equipment produced from such a sincere attitude are highly evaluated for performance and reliability that are not found in overseas products, leading to direct transactions with major manufacturers, and further development of next-generation product development, which we believe it leads to further orders.

The target areas are “semiconductor manufacturing equipment”, “equipment for social infrastructure”, “Equipment for general industry”. Since its founding, we have accumulated technological capabilities and expertise by concentrating our business in a balanced manner in these three fields, which creates stabilized management by dispersing risks such as economic fluctuations, and protect the environment in which employees can relentlessly devote themselves to manufacturing. Our products are active in places where absolute safety and reliability are required such as semiconductor, automobile, solar cell manufacturing site, mobile phone base station, defense, railways. Especially in the areas such as fast chargers for electric vehicles, which are expected to grow greatly in the future, business transactions are also expanding. Even today, the possibility of becoming the key to the future competitions in Japan are born from the hands of each employee, the technology that supports “MADE IN JAPAN”.
