At the center of our logo is the benzene ring, which represents benzene, a very important substance in the world of chemistry. Benzene is a very "stable" material, with carbon "C" at all vertices of the hexagon. And that "C" forms many substances by combining with various elements. On this earth where we humans live, there must be chemical substances with a benzene ring and "C" in everyone's field of vision.
“C partners Co., Ltd.” looks forward to joining as partners of various companies on this earth based on the services starting with "C", and facilitating clients to keep on their "stable" development. In the part of the blue circle that represents the earth, the chain that surrounds the earth represents the "C". This symbolizes our support on the development of your supply chain and the construction of management system that are spread all over the world.
Please share with us your vision.
As your partner, we are honored to help you reach your goals.


Representative Director
Yoshihiro Ogamo

It is a family of three, a wife and a daughter. After my child was born, I have become more concerned about harmful chemicals contained in food and personal belongings than ever before. Looking at child’s face makes me think about how to protect our global environment and pass it on to the next generation. Through consulting and auditing on Corporate Social Responsibility (CSR) and international sustainable certification, it is possible for companies to generate sustainable profits as well as to consider the natural environment in the supply chain. I hope this will ensure proper traceability of the products which we consumers pick up, improve the working environment in developing countries and Japan, and lead to many people working comfortably and living a comfortable life. In addition, every time I hear the news of people suffering from discrimination, various types of harassment, illegal labor, occupational accidents, etc. that are becoming apparent in Japan, I feel that the importance of CSR is understood and that it should be further permeated into society.
I started studying law while attending university (major in chemistry), and after graduating from university, worked in finance, trading, manufacturing and international certification body. Legal work such as negotiations with attorney, factory audit in automobile recycling industry, international certification audit (GRS, OCS, GOTS, RSPO), environmental committee member of the Japan Automobile Manufacturers Association, Inc. (domestic & global recycle), audit committee member of the Chiyoda-ward Ecosystem Promotion Council, CSR (labor, ethics, environment, occupational health & safety) audit of global supply chain (food industry, electronic industry, textile industry), EHS (environment & occupational health and safety) audit, government audit.
I have qualifications and experience of passing exams such as US Certified Public Accountant Exam (auditing and attestation), APSCA (Association of Professional Social Compliance Auditors), EICC (Electronic Industry Citizenship Coalition, now RBA The Responsible Business Alliance/Labor & Ethics), ISO9001 (Quality Management System), ISO14001 (Environmental Management System), ISO45001 (Occupational Health and Safety Management System), radiation protection supervisor, poisonous and deleterious substances, dangerous substances.
