Tatsuro Shirasu

Our company is based on the management principles of "Develop and provide products, technologies, and services that differentiate us from other companies, boost corporate value, and contribute to the creation of a prosperous society." Based on these principles, we focus on our two core areas of ferroalloys and functional materials to drive, grow and develop the company, while building mutually beneficial relationships with customers, suppliers, shareholders and other stakeholders.

Business Profile


As Japan's top manufacturer of ferroalloys, which are used as secondary raw materials for steel making, we have been maintaining domestic production of our main product, manganese ferroalloy, taking advantage of its cost competitiveness, due to the Tokushima Plant owning its own unloading berth. Furthermore, we have established our operational structure in globally competitive locations, shifting production of some products to overseas J/V companies.
Through such a structure, we are committed to continue to stably supply high quality products to various customers, such as major steel-making companies.

Functional Materials

As an ingredient of positive electrodes for lithium-ion batteries, lithium manganate helps provide the foundation for energy saving devices that contribute to carbon dioxide reduction, as does ferro boron, a raw material for amorphous alloys and NdFeB magnets.
Lithium-ion batteries are used in the power sources of electric vehicles (EVs) and hybrid electric vehicles (HEVs), and the electric power storage modules supporting smart grids. Amorphous alloys are used in high efficiency transformers, and NdFeB magnets are used in EVs, HEVs, and wind turbine generator motors. These contribute to building an environmentally harmonious society.
We manufacture and sell boric products used for making glass, dyes, etc. They are indispensable materials in daily life, and we have gained a good reputation for their quality.

Environmental Recycling Systems

Our 'contracted recycling' type ion exchange resin tower series enables water and resource recovery. This is a recycling system built by Nippon Denko, a manufacturer of metals and chemicals. We provide products for reduction, reuse and recycling (3Rs) that support a society with an environmentally sound material cycle. We also provide water purification devices equipped with ion exchange resins, reverse osmosis membranes, etc.

Other Businesses

Our Tokushima and Hidaka Plants are producing diverse fertilizers indispensable for soil improvement, by making use of the soil-improving properties of by-products obtained from ferroalloy production. Nippon Denko's fertilizers have earned a strong reputation for their significant effects, such as the improvement of soil and crop quality, stable cultivation, the enhancement of resistance to damage from disease, insect pests, and grain filling, and also the prevention of bending of plants due to stronger roots and stalks. We operate a hydraulic power plant at the Horoman River basin, located in Hidaka, Hokkaido, that supplies electricity to the Hidaka Plant and the Hokkaido Electric Power.
