CSR Activities at Plants

The Nihongi Plant is located at the foot of the nature-rich Mt. Myoko—one of the 100 Famous Japanese Mountains— and began operations in February 1920 as the birthplace of the Nippon Soda Group. On February 1, 2020, the plant celebrated its 100th anniversary, a significant milestone in our history. Throughout our 100-year history, we have continued our operations in close harmony with the natural environment and gained the deep understanding and support of our stakeholders including the local community through various interactions.
We promote CSR activities with the participation of all employees, and conduct business activities with meticulous consideration for not only process safety and disaster prevention, but also safety and health, environmental conservation, and quality assurance. Through these efforts, we aim to contribute to realizing a vibrant society, as well as to build a plant that earns the trust and provides peace of mind not only to all employees working at the plant but also to local residents. In recent years, we have engaged in community development activities in innovative ways together with the Nakago-ku General Office, the community development association, elementary and junior high schools, and other local residents, further strengthening our bonds with the community.
In anticipation of the next 100 years, we will transform our existing business structure from one centered predominantly on inorganic industrial chemicals to one focused on products with higher added-value, such as agrochemicals, pharmaceuticals, pharmaceutical excipient, and functional chemicals, achieving new growth for the plant through technological innovation. Moreover, to achieve zero accidents, zero disasters, and stable production, we will continue to engage in activities for environmental protection, process safety and disaster prevention, and safety and health with the united efforts of all employees.

Takaoka Plant started operation in 1934 by the Oyabe River in Takaoka City, Toyama Prefecture. The area sits amid the Tateyama mountain range, the Hida mountains and the Hakusan mountain range, which provide abundant water, and by Toyama Bay, which is rich in natural resources. Supported by abundant water and electricity, we manufacture basic chemical products through the electrolysis of sodium chloride (salt), which is the basis of the chemical industry. Using these chemical products as ingredients, we also manufacture functional chemicals and agrochemicals, essential items in modern society.
There are many issues associated with the process of manufacturing these products, including large amounts of electricity consumption and the generation of waste. Taking these issues seriously, we have been engaged in various efforts for conserving the environment, such as energy reduction and waste recycling. Since Takaoka Plant is a chemical plant, all employees working here handle hazardous substances professionally and safely. We also place strong emphasis on ensuring safety and disaster prevention so that even if an accident does occur we can minimize damage and prevent any impact on the environment or on residents in nearby communities.
We recognize that it is the responsibility of our plant and the Company to ensure the safety and security of the environment of Toyama Bay, one of the most beautiful bays in the world, as well as the local communities.

Mizushima Plant started operations in 1969 in the Mizushima Industrial Area, which extends from the mouth of the Takahashi River in Okayama Prefecture and has excellent access to supplies of industrial water, oil, and electricity, while being conveniently located for land and sea transportation. The plant received raw materials from neighboring companies. Because of the highly toxic cyanide handled at the plant, all employees working at the plant, including those of partner companies, are aware of the need to handle hazardous materials safely. We have engaged in CSR activities based on safety standards, including handling raw materials and products, use of protective equipment, and work procedures.
As announced on our website in March 2024, the decision has been made to close the Mizushima Plant during FY 2026/3, and production ceased as of December 2024. Even during the period leading up to the factory’s closure, we will continue working toward the key goal in our plant’s policy to achieve zero accidents and disasters.
We will therefore undertake the necessary work to close down the plant with safety as our top priority, and will continue to conduct inspection patrols, emergency drills, education, and other activities to ensure occupational safety and health.

The plant started operations in 1969 as Nissou Kasei Co., Ltd., in a section of the Keiyo Industrial Zone, which faces the east side of Tokyo Bay. In 1999, it became the Nippon Soda Chiba Plant, which it has remained to the present. Rather than large-scale generic petrochemical products for general use, the Chiba Plant produces chemicals with a focus on specialty chemicals at mid-sized plants. Common applications for our products include liquid polybutadiene as a raw material in acrylic paints used in smartphones and for printing plates, and VPPOLYMER as a widely used, key material for photoresists, which are essential for the manufacture of semiconductors.
In December 2024, we finished installing solar panels on the plant premises, and the solar power generation system went into full operation. This system will allow us to reduce CO2 emissions by approximately 1,140 metric tons annually. As a chemical plant located in the greater Tokyo region, a great deal is required of us.
Our foremost priority is to ensure zero accidents and zero disasters, and with safety and reliability as our watchwords, all who work at the plant engage in activities for environmental protection, process safety and disaster prevention, and safety and health. By providing a stable supply of various products that support people’s lives, our aim is to become a plant that is valued by all.
