Company Overview

Message from the President

Mitsubishi Nagasaki Machinery is a company involved in skilled manufacturing of industrial equipment in Nagasaki, which has deep ties to Mitsubishi, and bears both in its name. Since the start of the business that led to our company, we have overcome a history of hardships, including reconstruction from devastation caused by the atomic bombing towards the end of WWⅡ, and we are a company that has continued to pursue skilled manufacturing with resilience, flexibility, and spirit.

Our company’s predecessor was the Mitsubishi Steel Manufacturing Co., Ltd. Nagasaki Steel Works, and its origins can be traced back to the Nagasaki Steel Works of Mitsubishi Shipbuilding & Engineering Co., Ltd., which was established in 1919. In 1975, the company was reorganized and established as Mitsubishi Nagasaki Machinery Mfg. Co., Ltd. with the Industrial Machinery Division and the Steel Fabrication and Machining Division as its main businesses.

We supply a wide range of products to the world with our solid technological capabilities based on an advanced fusion of engineering and manufacturing: in the field of industrial machinery, from our world-renowned large industrial machinery such as forging presses and ring rolling mills, to magnetic separators, anti-vibration devices, and weighing instruments; and in the field of steel fabrication and machining, from large steel structures to super-high pressure equipment for energy, steelmaking, and various plants.

We have capabilities equivalent to those of a major heavy industry manufacturer with the mobility of a small operation, and our ability to meet diverse customer needs is one of our strengths.

Recently, the business environment has been undergoing significant and rapid changes, and we have made an effort to be quick to respond to them. While identifying what to protect and what to change, we will continue to transform and evolve, even as we protect the basics of skilled manufacturing. We will achieve sustainable growth through rolling medium-term business plans that incorporate the evolution of existing businesses and the challenge of new fields.

Going forward, through business activities based on compliance management that also balance business performance with solutions to corporate ESG and other social issues, we will strive to be a company that is trusted and needed by our customers, society, and the local community.

We look forward to your continuing patronage and support.

President　Tetsuo Kuga
