Quality Control

The basic stance of the Nikon Group is to make social and economic contributions through activities that provide products and services useful for society.

Quality Control for Products and Services

The Nikon Group has stipulated the following Basic Quality Policy.

Policies and systems for quality control

Basic Quality Policy
Based on its corporate philosophy of "Trustworthiness and Creativity," Nikon has established the following Basic Quality Policy. It aims to provide products that exceed the expectations of customers and contribute to the healthy development of society.
  1. Through creative and efficient manufacturing, enhance brand value and provide high-quality distinctive products to the market in a timely manner.
  2. Provide safe and environmentally friendly products to earn the trust of customers and society.

In order to implement the Basic Quality Policy, the Nikon Group has set its Quality Control Directive (QCD) as its basic rules on quality control. In the year ended March 31, 2013, we completely revised the QCD to clarify its relationship with ISO 9001. Moreover, we added environmental items to make it more consistent with other standards. We will share the revised rules across the Group to promote the provision of even better products and services.

Quality Control Committee

The Quality Control Committee deliberates and makes decisions on important issues in relation to the implementation of the Basic Quality Policy. Also, the committee strives to improve the quality control systems and conducts prompt reviews of them to ensure that they are working effectively.

ISO 9001 certification and consistent compliance with the "Quality First" policy

The Nikon Group is conducting business operations in line with its ISO 9001 Quality Manual, created based on the QCD, and all business segments of Nikon Corporation and major Group companies have acquired ISO 9001 certification. We also conclude quality assurance agreements with our business partners based on their understanding of the Nikon Group's "Quality First" policy. Moreover, every November, which is designated "Quality Month" in Japan, we invite external experts to give lectures so that employees of both the Nikon Group and their partner companies can improve their quality-related skills. In the year ended March 31, 2013, we invited Mr. Kazuhiko Noguchi from Mitsubishi Research Institute to Nikon Corporation's Ohi Plant to speak. His lecture, on the application of advanced risk management for quality improvement, was attended by 71 directors and employees of the Nikon Group as well as 106 employees of the Group's business partners.

Quality control audits

In the Nikon Group, quality control audits based on the QCD are conducted by a top executive. Specifically, the executive inspects, checks, and evaluates the quality control activities conducted at Nikon Corporation and Nikon Group companies to help them improve the quality of business operations as well as the quality of products created through these business operations. The audited companies are required to make corrections and improvements to rectify any shortcomings found in the audits, a process that leads to more appropriate quality control activities at the companies. Important findings are reported to the Executive Committee and are also used to improve internal controls. In the year ended March 31, 2013, quality control audits were performed at four departments of Nikon Corporation and at six major Group companies.

Product safety assurance

The Nikon Group gives due consideration to the safety of its products throughout their life cycle, starting from the initial planning stage.
Specifically, we design our products in line with the Safety Design Principle that we have formulated based on relevant international standards, and then confirm their safety through measures such as design reviews and inspections carried out during the production process. We also obtain safety certification from third-party certification bodies as necessary. Furthermore, our Product Safety Test Room ensures that only safe products reach our customers. This testing facility has passed stringent certification criteria based on the international standards set by TÜV SÜD Product Service GmbH, Germany, a certification body that tests laboratories in Europe.
In the fiscal year ended March 31, 2013, we published 28 test reports collating the results of the various tests that were conducted.

Information Disclosure in Case of a Safety-Related Problem

If a problem with product safety or quality arises, information is disclosed to customers as soon as possible and countermeasures are taken immediately after thorough investigations into the matter.
