Quality is the first priority of our products.We set up product quality assurance system starting from raw materials receiving process until finished products
     are delivered to our customers including after-sales warranty to ensure that NHK Spring's products meet global quality standards.

     In addition, "Culture of Quality" is what we have always adhered to, which consists of 5 principles:

       First : Customers are the first priority.
       Second : Provide maximum satisfaction to customers.
       Third : Next process is customer. (Inside Customer)
