About Us

Appreciate every encounter with people and live today.

Nagase was started in 1950 by Noboru Nagase as a machine manufacturer owing only one turning lathe. Since its foundation, Nagase, as a growing manufacturer of super-precision grinders and nano machines, has been dedicated to “customer-oriented service”, “originality and ingenuity” and “creative technology”. Nagase’s strength is development. Here is the history of Nagase.

* Head office and factory in 1960

Foundation – Company Establishment

During WWII, Noboru Nagase, founder, was a master turner at a munitions plant. After the war, he started machine assembly in a space under the eaves of his wife’s parent’s place. Due to increased demand because of the Korean War, he developed many innovative machines, leading to the creation of Nagase.

1950 Noboru Nagase, founder, started machine manufacture in Kikuchi-cho, Gifu

1951 Developed vertical sawing machine GN-360 (patented)

1952 Developed compact vise (ORIGIN)

1956 Developed fully automatic hydraulic horizontal saw machine (equipped with saw blade clamper)
* Founder awarded Medal with Yellow Ribbon
from the government for this development. 

1958 Developed hydraulic No. 2 vertical milling machine


Growth – Becoming a Machine Manufacturer

At the height of Japan’s economic boom, Nagase, incorporated in the late 1950s, expanded a reinforced concrete factory in Kagura-machi, Gifu. Around this time, the first hydraulic grinder was developed in response to market demands for inexpensive surface grinders increased. The following year when the Tokyo Olympic Games were held, a cutting tool grinder was developed, which is still manufactured today.

1958 Established Nagase Ironworks Co., Ltd.

Development - Mass Production Based on Price Concept

The head office and factory was moved from Gifu to the current location. Located along the Mugi River upstream of the limpid Nagara River, the Nagase factory is blessed with expansive premises and clear water and air, which are indispensable for manufacturing accurate machines. This area is also a strategic point for transportation, and ensures smooth shipment of products to each destination. In this environment, we have been operating with the goals of manufacturing high quality products in a rational and timely manner.

Exploration - Development of Various Industrial Equipment

The Japanese economy was hit by significant business fluctuations due to the Nixon shock and oil shock in the 1970s. Nagase, which seemed to have enjoyed smooth sailing until then, was not an exception at that time. In the midst of overseas advance and production by major manufacturers, Nagase explored the best way to go while undertaking the development of various industrial machines.
