The Group works to prevent air, water, soil, noise, vibration, and odor pollution and each base sets stricter voluntary standards than the legal emissions standards for pollutants and applies them daily. Additionally, we have put goals in place for the prevention of environmental pollution for the Medium-Term Environmental Action Plan 21-25, and we are working to achieve them.
We also work to prevent the external leakage of PRTR substances, VOCs, PCBs, and other substances, which are regulated by laws, and reduce the amount we handle.

The Group conducts land use history surveys of domestic bases where it owns land to identify soil contamination risk. If the survey finds that the soil or groundwater is contaminated, we notify the authorities and take appropriate action.

At our domestic bases, we monitor noise, vibration, and odor in accordance with related laws and regulations and confirm that they are within the established standards.

Based on the Law concerning Pollutant Release and Transfer Register/PRTR Law, the Group manages the amount of PRTR substances handled at our facilities and the emissions to the environment, and properly notifies the prefectures where we are located.
All organic waste solvents containing PRTR substances discharged from the research centers are treated as industrial waste to minimize the discharge to public water areas.
We are also studying the manufacturing processes and reducing the amount of target organic solvents used.
We are reducing VOC emissions by managing emissions and the amount handled, setting up collection facilities, and reducing emissions into the natural environment.

We completed disposal of high-concentration PCB (polychlorinated biphenyl) devices at the Group’s domestic bases by the disposal deadline.
Furthermore, we are conducting a confirmation survey of items with a low concentration of PCBs, including notification from the Ministry of Economy, Trade and Industry (March 31, 2022), and plan to move ahead steadily to complete disposal by March 31, 2027, the disposal deadline.

Surveys for sprayed asbestos have been conducted at domestic Group bases in the past under the Ordinance on Prevention of Asbestos Hazards, and we are taking relevant measures to prevent asbestos scattering. Additionally, when removing facilities, we check for the presence of asbestos in the sprayed materials, insulation, and building materials to be moved, and report the results of these checks to the government.

The Group is engaged in drug discovery research aimed at various modalities, and opportunities to handle various research materials and samples are increasing. In the use of genetically modified organisms, we have established in-house regulations based on relevant government and ministerial ordinances, such as the “Law Concerning the Conservation and Sustainable Use of Biological Diversity through Regulations on the Use of Living Modified Organisms (Cartagena Act),” which we comply with. Moreover, the in-house Ethics Review Committee prevents the spread of living modified organisms by receiving preliminary reviews of measures to prevent the spread of these organisms into the environment.

In addition, regarding the use of pathogens and research materials and samples that may contain them, we have established internal regulations based on laws and regulations including the “Act on the Prevention of Infectious Diseases and Medical Care for Patients with Infectious Diseases (the Infectious Diseases Control Law)” and prevent the leakage of pathogens.
