Supply Chain Management

Promotion of Sustainable Procurement

Approach to Promotion of Sustainable Procurement

We have established the procurement policy and the CSR policy in compliance with the international code of conduct to ensure compliance with respect to labor, the environment, safety, quality, etc. in our supply chain so as to contribute to society. We are working with our business partners to make improvements so that we can establish sustainable procurement activities.

Basic Policy for Material Procurement

We shall comply with the laws and regulations of each country, social norms, and the CSR Code of Conduct, and conduct procurement activities with integrity based on corporate ethics.

We shall implement initiatives concerning the CSR Code of Conduct in line with the RBA Code of Conduct and strive to eliminate adoption of conflict minerals.

We request that our suppliers cooperate with us in ensuring compliance with laws and regulations and social norms in our supply chain.

2.Prioritization of the environment

We shall conduct procurement activities with full consideration for conservation of the global environment and reduction of environmental impact in order to realize a sustainable society in harmony with the environment through our products and services.

We request that our suppliers follow our Green Procurement Guidelines and make efforts to conserve the environment and use and produce parts and materials with less environmental impact.


We shall deepen mutual understanding with all our suppliers based on better partnerships and value relationships rooted in trust.

4.Open door

We shall conduct the best possible business transactions, both in Japan and overseas, based on the principles of free competition. 

We shall always deal fairly and impartially with all of our suppliers. We select suppliers through appropriate procedures, considering material quality, delivery dates, prices, reliability of management, and the technological development capabilities of the suppliers, as well as evaluating whether they are fulfilling their social responsibilities.

We shall respond in good faith to our suppliers’ requests and inform them of the information necessary for the transaction. At the same time, we seek useful information from our suppliers. We shall strictly manage trade secrets provided to us and maintain confidentiality.

CSR Procurement Initiatives

We have strengthened our CSR supply chain management in accordance with the RBA*1 Code of Conduct, and share our CSR mindset with our business partners. We have established a new Green Procurement Guideline*2 and require all business partners to submit a consent form to ensure our Basic Procurement Policy and CSR Policy are thoroughly instilled across the supply chain. 


Responsible Business Alliance. Consisting mainly of US-based companies, it has members from around the world. Since the alliance's formation, its main purpose has been to exercise social responsibility. It has formulated a Code of Conduct which includes suppliers and works to promote its widespread adoption.


Our Green Procurement Guideline lays out our action policy, covering topics such as our philosophy on green procurement, inspection of chemical substances and high-risk minerals contained in supplies, and list of self-managed substances.


Measures against the Issue of Conflict Minerals

Regarding conflict minerals*, we are strengthening initiatives by promoting information sharing with our business partners in order to ensure that our procurement activities across our supply chain do not benefit armed groups that encroach upon human rights.


Conflict minerals: Tin, tantalum, tungsten, gold (collectively “3TG”) as well as cobalt from the Democratic Republic of the Congo (DRC) and adjoining countries are designated as conflict minerals.
