Water Neutrality



Since its establishment, the Otsuka group's operations have had a deep connection to water, a resource essential to life. Through products that use water as a raw material, we have actively contributed not only to the treatment and prevention of diseases, but also the maintenance and promotion of health. We therefore recognize the importance of water to us as a resource, and consider its conservation to be a critical global issue. Moreover, water resources are unevenly distributed across different countries and regions, each of which faces different risks. We cooperate with all stakeholders, and conduct ongoing water conservation initiatives from intake to discharge (including cultivation of water resources, conscientious use and clean return), in the aim of sustainable water use.

Evaluating Water Risk at Manufacturing Sites

Considering environmental risk in each region is also important for sustainable growth in the diverse business models of the Otsuka group operating around the world. Since 2017, the Otsuka group has conducted primary water risk assessments at all consolidated manufacturing sites using the water risk assessment tool “Aqueduct,” developed by the World Resources Institute (WRI), so as to understand and minimize the impact of water-related risk on the group’s business activities. We also formulate analysis records for each site and implement comprehensive risk assessment by utilizing more detailed water data and collaborating among group companies. We will pursue the water resource conservation improve and use efficiency by identifying regional risks and promoting more specific research and collaboration among group companies, and by taking measures for region-based management and effective utilization.

Initiatives that Protect Water Sources through Forestry

One of our initiatives to cultivate water resources uses water conscientiously and returns clean water using water source protection* through forestry. Group employees and family members voluntarily participate in conservation drives, such as planting trees, in turn developing a sense of closeness with forests. These nurturing activities help to protect our rich natural environment and water resources, and are one of the Group initiatives that ensures a sustainable future.

  • Water source protection means nurturing and maintaining water resources, as well as using the natural capacity of forests to mitigate flooding and droughts. Forests soak up falling rain and snow, then allow that water to slowly flow into rivers as groundwater.


【In Japan】  
The Otsuka group has signed a partnership agreement with Tokushima Prefecture’s Tokushima Forestry Project, taking part in intensive forest management that is focused on large-scale forests covering 100 ha or more.


■Tokushima Forests – Forestry in Collaboration with Tokushima Prefecture  
In 2010, Otsuka Pharmaceutical Factory and Taiho Pharmaceutical signed partnership agreements with the Tokushima Cooperative Forestry Project, based on Tokushima Prefecture's Ordinance on Promotion of Global Warming Countermeasures. These initiatives have since grown, and currently eight Otsuka group companies have signed partnership agreements.
