Representative Director, Executive President
My name is Kazufumi Yokogawa, and it is my pleasure to serve as the Representative Director and Executive President of Tanaka Chemical Corporation. In the secondary (rechargeable) battery market where significant growth is expected, we will make our utmost effort towards stable and continuous company growth.
Tanaka Chemical Corporation is a company specializing in a single segment, i.e. positive electrode materials for secondary batteries. We focus on development and manufacturing of materials for Ni-MH batteries, and especially for Lithium-Ion Batteries. Though the secondary batteries are widely used for electrical appliances such as mobile devices, as well as vehicles such as Hybrid Electric Vehicles (HEV), most especially the market for vehicle batteries is rapidly expanding in a trend toward Electric Vehicles (EV). In order to respond to this trend, it is necessary to develop a higher-performance secondary battery, providing it in a timely manner to the market, satisfying demand in quantity and price, by keeping our traditional business style while providing a custom-made product to fit the needs of each customer. Under the current fortuitous opportunity where our market is experiencing explosive expansion of secondary growth, I believe our company will be able to see substantial growth through the achievement of these efforts,
In addition, in the rapidly growing market for vehicle batteries, the failure of an equipped secondary battery will damage vehicle performance, and will directly affect its safety. Therefore, a quality control factor for batteries is an essential requirement, even more than before, and we are also committed to improving our ability for numerical and theoretical analysis.
We value the credibility for our product earned from our customers in many years of experience. Furthermore, we value our technologies, such as Particle Sphering Technology which controls particle formation, and Multi-element Co-precipitation Technology which co-precipitates various elements at the atomic level. While being based on these advantages that Tanaka Chemical Corporation has, we aim for further growth in our company, coping speedily with environment changes in the market, and deepening a collaboration, versatilely with our parent company, Sumitomo Chemical Co., Ltd. in the area of development of higher-performance secondary batteries, the expansion of production capacity responding to market growth, the pursuit of rational production methods, and the improvement of numerical and theoretical analysis.
I would like to thank all of our customers, stake-holders and employees, for your continuous understanding and support.

We Pursue Quality in Every Process from Development
and Production to Distribution
We pursue a high level of quality in the total flow of our operation; from R&D and production technology, development of production facilities and equipment, to distribution and management. We keep maintenance and quality control at the highest level by carrying out chemical composition analysis of raw materials, intermediaries and final products, as well as physical characteristic analysis of crystallinity, viscosity and filling density of powder products. Through these achievements, we acquired ISO 9001 certification in October 2002. While valuing the fundamentals of manufacturing we, as a leading company in the industry, continue to take on the challenge to achieve further advancement in quality at an extremely high level.

Building a Recycling-oriented Society
In aspiring to carry out business activities and provide products that are friendly to the environment, we undertake continuous ecological improvement efforts through the establishment of an environmental management system. In 1999, we acquired ISO 14001 certification for our environmental management system. In 2011, we acquired a high rating in “Environmental Rating”, run by the Development Bank of Japan (DBJ) for “advanced effort for consideration towards the environment”.
We consider environmental protection as one of the important issues of management, and are striving to reduce our environmental impact across the board, from material procurement to development, production, logistics and waste disposal.
In May 2011, we received an environmentally rated financing from the Development Bank of Japan (DBJ) in which we were rated for “advanced effort for consideration towards the environment”.
