Message from President
We will continue to contribute to society with the aim of "creating a future with dreams."
Since our establishment in 1932, we have been supporting the field of "Monozukuri" (manufacturing) as a specialized manufacturer of diamond tools, as well as supporting the production of useful products for an affluent life. The products and services we have provided to the world are being used at the sites of production activities in the most advanced fields of the times in various industries such as semiconductors, electronic devices, information and communication equipment, automobiles, medical and construction industry.
Humans have been creating many things in search of an affluent life. However, as a company involved in the manufacturing industry, we have very mixed feelings when we think that the more things are developed and the more affluent we become, the more they lead to the deterioration of the global environment.
On the other hand, an affluent life requires goods, and manufacturing will unquestionably continue and even expand in the future in the pursuit of affluence. Nowadays, in order to create a sustainable and better world, we are required to understand global issues and tackle them as a corporate activity, and many companies are now aiming to do so.
Based on our management philosophy of "continuing our operations that contribute to a safe, secure environment following its natural circulation law," we will continue to aim for manufacturing that leads to the creation of a better natural environment.
We believe that pursuing the required performance of tools and continuing to contribute to quality and productivity improvement will lead to a reduction of the burden on the global environment, even in a society where affluent lifestyles and manufacturing are expanding.
Today, in the field of information and communication technology, the use of big data and AI are rapidly evolving and beginning to penetrate deeply into our lives. In the future, we will continue to see widespread technological innovation in new situations and environments, such as "automated driving," "robotics," and "next-generation communication standards," at a speed completely different from that of the past.
We will continue to refine our original discoveries and ideas while maintaining a broad perspective toward the future, and to contribute to society by playing a role in the most advanced fields in the midst of rapidly changing technological innovation.
We look forward to your continued support in the future.
We make efforts to the best of our ability to attain our high technological missions,
based on the excellent characteristics of diamonds, for a considerate society, and continue our operations
that contribute to a safe, secure environment following its natural circulation law on the manufacturing products.
