Environmental problems are important issues that are shared by people all over the world, and companies’ efforts to reduce their environmental impact have influenced the quality of management and, in turn, the evaluation of their products.
Nakanishi has been working on environmental issues from early on, and in January 1999, acquired ISO 14001 certification, a global standard for environmental management systems.
In all of our corporate activities, including the development, design, manufacture, sale, and service of dental and other ultra high-speed rotary products, we will implement the following environmental activities with the aim of reducing the environmental impact for the future global environment, harmonizing with nature, and creating a healthy and prosperous society as the basis of our management.
