At the TS Development Group, we focus on developing optical materials centered on photochromic materials*, working closely with manufacturing and sales teams while meeting customer needs. Specifically, we aim to commercialize a wide range of development items by utilizing technologies such as molecular design and synthesis of photochromic dyes, formulation design and material synthesis for coating and sheet materials, and organic-inorganic hybrid technologies.
* Photochromic materials: Materials that change color when exposed to ultraviolet light. They are used in eyeglass lenses to protect the eyes from ultraviolet light.

Healthcare Development Dept.

We strive to leverage our group's technological capabilities throughout the cycle of health, prevention, diagnosis, treatment, and prognosis to contribute to life support and the improvement of quality of life (QOL). Currently, our main focus is the development of active ingredients (such as APIs, supplements, and vitamins), cosmetic materials, and medical materials related to diagnostic agents. On top of these products that are received by many professionals, in response to the recent diversification of modalities, we are also working on handling biomaterials and developing alternative materials. Tokuyama collaborates with domestic and overseas partners in the development of these products, which are manufactured and marketed globally.

IC Chemicals Development Dept.

Our core products, including high-purity IPA and TMAH, are semiconductor chemicals used in the manufacturing of advanced semiconductors. Based on insights gained through marketing activities, we leverage our proprietary technologies to develop new application products that precisely meet customer needs.
Our mission is to contribute to performance improvements and problem-solving for next-generation semiconductors. Acting simultaneously as researchers, marketers, and sales professionals, we strive each day to be trusted partners whom customers can rely on for consultation when they face challenges.

Electronic & Advanced Materials Development Dept.

As the developer of new products for the Electronic & Advanced Materials Division, the Electronic & Advanced Materials Development Department carries out research and development to create highly functional materials for semiconductors. Its work helps to support today's advanced information and telecommunications networks.
For semiconductor chemicals such as high-purity IPA and TMAH, the Department is working to further enhance its proprietary ultra-high-purification technologies. It is pursuing the development of next-generation chemicals with new functions to better match market needs. As part of the development of silica and silica composite materials, the Department has thoroughly refined its technologies for precise control of particle shape and surface conditions. This is especially important for advanced semiconductor encapsulants that support ultra-miniaturization and high levels of semiconductor device integration. Based on a precise understanding of market needs, the Department is accelerating development to deliver numerous cutting-edge products.
In the area of heat-dissipation materials, the Department is working to develop new materials based on aluminum nitride technology, where Tokuyama has the world's top market share. These materials help to deal with the increase in heat generation density, which has become a serious issue with today's high levels of semiconductor device integration.

Eco-Business Development Dept.

The Eco-Business Development Department develops waste material recycling technologies and creates new businesses to help reduce environmental impact. While focusing on waste materials that have traditionally been difficult to utilize in cement production, the department also sets its sights on developing technology for all kinds of waste that are considered difficult to treat. In the process of selecting targets and in consideration of business development, the department collaborates with the Recycling & Environment Promotion Department to better understand the needs of the market. One example of achievements is the original technology it created for recycling waste plasterboards. It established technology for enlarging crystals via crystallization reactions and launched a new business in this area via Tokuyama Chiyoda Gypsum Co., Ltd.

Chemicals Development Dept.

The Chemical Development Department is committed to providing basic chemicals that are essential to the fabric of society. Looking 10 to 20 years into the future, the department also seeks to expand into the energy and environmental fields, engaging in a wide array of development activities designed to contribute to society. Drawing on expertise in chlor-alkali electrolysis, the process which produces caustic soda and chlorine, the department works to develop world-leading high-performance electrolytic cells with innovative ideas that have never been tried before. Backed by a storehouse of manufacturing techniques, the department is also pursuing a range of projects, such as manufacturing and development of high-performance hydrogen materials with promising applications in the food and heath domains. It is also developing CO₂ capture and concentration technologies based on the soda ash production process, Tokuyama's flagship field of expertise since the beginning. With these and other endeavors, the department is taking up the challenge of helping to build a sustainable world.

Cement Development Dept.

As the central R&D organization of the Cement Business Division, the Cement Development Department carries out basic research, technology development and product development in fields such as cement and concrete, resource recycling, cement-based solidifiers, and construction materials. In addition, as part of the Group's efforts to help mitigate global warming, the department is working hard to develop technologies for reducing CO₂ emissions in the production of cement, including carbon capture and fixation.
Cement and concrete-related technologies are at the foundation of all R&D efforts for the Cement Business Division. Accordingly, the department focuses on creating more sophisticated quality evaluation technologies for cement clinkers, as well as collecting basic data on the physical properties of concrete. In the field of resource recycling, the department is exploring techniques for utilizing more types of waste matter as materials for cement or fuel for production while maintaining high product quality.
As conditions surrounding the cement industry grow increasingly difficult, the department is making every effort to fulfill the social mission expected of the industry by developing technologies that help enhance social capital while contributing to the development of a recycling-based society.

Bioethics

When conducting research and product development in the fields of Medical and Biological Research, Tokuyama deliberates through the "Bioethics Committee" to protect the human rights of research subjects, ensure their safety, and improve their welfare, while also ensuring ethical validity.
This committee operates in accordance with regulations based on the "Ethical Guidelines for Medical and Biological Research Involving Human Subjects" and notifications from relevant government agencies.
