We will always continue to be “No. 1”
with our “Only One” technology that
responds to the needs of our customers.

KOBELCO has continued to develop new products and technologies since it produced compressors for the first time in Japan in 1915. The “KOBELCO” brand and its products receive high evaluation both in Japan and overseas. We also produced the first screw-type air compressor, freezer, and vacuum pump in Japan. By reading customers’ needs and addressing them, we have produced our original technologies and “Only One” products that cannot be found anywhere else. Such achievements and experiences have lead to the development of our latest model and we have thus been “No. 1” in respective times. We will continue to be the front-runner in the industry by reflecting customers’ views in our technology and product development.
