COMPANY PROFILE Providing Technology to Society Transforming Technology into Pride Tokuyama's technology, based on chemistry, creates the value that customers truly want.

Japan was once completely reliant on imports for its soda ash. In 1918, Tokuyama Corporation was established in Tokuyama (now Shunan City), Prefecture to remedy this lack of a domestic source.

Tokuyama later began producing cement, and then responded to the growth of ’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. VISION STRATEGY OF TOKUYAMA 【 New Foundation 】 【 Business Strategy 】

Since its founding, Tokuyama has had special advantages based on its highly efficient production facilities and its in-house power generation capacity, which is among the best in the nation. The company has exploited these strengths to develop traditional businesses such as chemicals and cement. More recently, MISSION Tokuyama entered the field of specialty chemicals, and the expertise it has gained through the business Centered on the field of chemistry, the Tokuyama Group has enabled the company to develop technical prowess in new fields. will continue to create value that enhances people’s lives Foundation Strengths Good natural port Highly efficient Japan s 8th leading ’ Employee integrity and competitive Tokuyama Factory in-house power Sound management and perseverance industrial complex through integration generation capacity
