Technology for the World KURAKI


Nagaoka Quality

Our engineers are enthusiastic about manufacturing machine tools, and their passion contributes to global engineers manufacturing other products.

Message from the President

We have been supplying innovative,
high quality products from the city of Nagaoka to our customers worldwide.

Hiroshi Yasukawa, President

KURAKI Co., Ltd. was founded in 1938 in Nagaoka — located in Niigata Prefecture of Japan — and it has been growing as a company to support the foundation of manufacturing ever since. Nagaoka is a city filled with traditional crafts and cultures. Inheriting the history and culture of Nagaoka, we have continuously strived to improve our technologies.

KURAKI’S technologies and machines are called “Mother Machines (machines that manufacture machines),” and they generally do not get much attention. However, it is exactly because they aren’t widely recognized that they must be carefully evaluated for progress.
For 80 years, we have been doing just that, and continuously evolving with our customers.

We have expanded our business not only in Japan but globally. Our products are used in the manufacturing of your electric appliances, automobiles, aircrafts, ships, and smartphones, supporting the development of a wide array of technologies. We believe this is all because we have listened to and made full use of feedback from our customers when developing our technologies.

KURAKI will continue to take pride in supplying innovative products of the highest quality — what we call “Nagaoka Quality” — from our here in Japan to our customers worldwide.

Hiroshi Yasukawa, President

Business Areas

The core businesses of our company focuses on the development, manufacturing and sale of “machine tools”. Our product portfolio comprises Horizontal Boring & Milling Machines especially designed for heavy duty machining in large-sized and heavy workpieces. This flagship of our company is offered in various models tailored to the specific customer’s requirements. The technologies developed and refined in the course of the design of these boring mills enabled us to also engage in the manufacture of “special machinery” for high-precision machining and mass production in a wide variety of applications such as automotive engineering, ship building and medical equipment. These technologies combined from perfect synergies to continuously increase our know-how and experience enabling us to provide manufacturers with highly efficient and high-value machines which frequently lead to the development of innovative products.
