COMPANY PROFILE

Providing Technology to Society

Transforming Technology into Pride

Japan was once completely reliant on imports for its soda ash.

In 1918, Tokuyama Corporation was established in Tokuyama (now Shunan City),

Yamaguchi Prefecture to remedy this lack of a domestic source.

Tokuyama later began producing cement, and then responded to the growth of Japan’s chemicals

industry by adding a broad array of chemicals to its product lineup.

The company’s main business fields are: information and electronics,

where its main product is polycrystalline silicon, which has numerous semiconductor applications;

life and healthcare, which includes eyeglass lens materials, dental materials, and other such products;

and environment and energy, which includes resources- and other environment-related businesses.

At the Tokuyama Group, we are committed to creating value centered on the field of chemistry.

In the process, we can do our part to help enhance people’s lives as well as build a better society.

Tokuyama's technology, based on chemistry,creates the value that customers truly want.

Taking responsibility as the only soda ash manufacturer in Japan ̶ Leveraging reliable technologies to assure a stable and continuous supply of products to customers

Soda ash is a basic chemical used as a raw material in the production of glass, soap, and other products. Up until the early 20th century, Japan had completely relied upon imported soda ash. Aiming to remedy such constraints, i.e. the lack of a domestic source, Tokuyama (then “Nippon Soda Kogyo”) was established in 1918 to begin soda ash production domestically. Since then, the soda ash business has been a mainstay of Tokuyama’s traditional businesses.

The high safety and reliability of plant and equipment for soda ash, calcium chloride and sodium bicarbonate, along with the strict product quality controls, enable Tokuyama to manufacture food additive grades in addition to industrial grades.

Technologies have evolved and accumulated in the century since Tokuyama’s establishment, and the earnest efforts of Tokuyama employees continue to ensure “Tokuyama quality.”

High-quality caustic soda, manufactured using an ultra-energy-saving process at a large-scale plant

Caustic soda is produced by the electrolysis of brine. Tokuyama is one of the largest manufacturers in Japan. Its advanced ultra-energy-saving technology is highly appreciated, and won the Japan Soda Industry Association Prize for Technology in 2007.

High-purity chlorine and hydrogen, by-products of caustic soda production, are supplied to work sites throughout the Tokuyama Factory and used widely as raw materials for an array of derivatives and products.

Caustic soda is a basic inorganic chemical with a very wide range of applications. It is used in the manufacture of paper, synthetic fiber, soap, chemical seasonings, and so on. Tokuyama does its utmost to assure a stable and continuous supply, living up to the pride acquired over its long history.

High-purity aluminum nitride powders produced using Tokuyama’s proprietary technology have extremely few impurities and feature high heat dissipation (thermal conductivity) as well as electrical insulation.

Tokuyama’s aluminum nitride products are used as heat dissipation material for such applications as micronized semiconductor devices, the operation of which becomes unstable when heated, and industrial electronic equipment which generates high heat. The company’s aluminum nitride powder holds a 60% share of the global market. This is one of the company’s highest value-added products which contributes to technological innovation.

Leveraging outstanding quality and R&D capabilities to provide the polycrystalline silicon that supports the ongoing miniaturization of semiconductor devices

The Tokuyama Factory is a world-leading manufacturer of high-purity polycrystalline silicon, which is produced as a raw material for silicon wafers. All of Tokuyama’s advanced purification technologies are utilized to develop the company’s polycrystalline silicon.

The raw material for polycrystalline silicon is silica stone. Through a reduction process, silica stone is turned into metallic silicon, which is then reacted with hydrogen chloride to produce trichlorosilane. This is purified by distillation, and reacted with hydrogen to produce high-purity polycrystalline silicon inside a bell jar.

Outstanding quality and the highest level of purity in the world are what make Tokuyama so competitive. Further growth of the business can be expected.

Recycling and Environment BusinessTokuyama uses a wide variety of waste materials as alternative raw materials or as recycled fuel in its cement kilns. Careful inspections are carried out to ensure an environmental friendly manner of operation.

Major Products Waste plastic recycled as an alternative fuelMunicipal incinerator ash recycled as an alternative raw material for cementGypsum recycled from wasted gypsum board

Main applications

Buildings Dams Bridges

Commitment to recycling material Cement Business : Helping to realize a recycling-oriented Society

Tokuyama’s cement business was started to utilize waste material generated from the production process of soda ash. In 1995, Tokuyama succeeded in becoming the first manufacturer in the cement industry to use waste plastics as an alternative of fuel in the front section of a cement kiln (rotary kiln), and established a technology.

The production capacity of the Nanyo Plant of the Tokuyama Factory, as a single factory, is one of the largest in Japan. Cement-related products from here, such as cement and cement soil stabilizer, are used in construction of buildings and lifeline support facilities such as port facilities, bridges and roads. These materials are indispensable components of social infrastructure.

People are refined by another.Tokuyama’s journey in pursuit of cement and other technologies has reached 100 years. Odyssey continues further

In the cement production process, Tokuyama accepts a large volume of waste materials, including waste plastics which are generated from manufacturing activity of outside companeies and municipal incinerator ash which is generated from incineration of household waste, and uses them as alternatives of raw materials and fuels.

Highly sophisticated operation skills are necessary to use waste materials as alternatives, because waste materials are inconsistent in terms of quality. Thus, in cement production, it is vitally important that the operation skills of veteran operators are passed on to younger operators.

Tokuyama has a unique approach of training which requires the trainee to “plan and do on their own”. Firstly, the trainee (younger operator) is given instructions of job from trainer (veteran) at their workplace, and then the trainee drafts a personal work plan by foreseeing and taking notes on hidden risks and remarkable points before he does the job.
