Our main initiatives

Creating Biotopes1

Otsuka pharmaceutical’s Tokushima Itano Factory has created facilities that are friendly to people and the environment on the basis of building harmonious relationships with the natural environment. The design of the factory complex includes incorporating the pre-construction landscape, and reintroducing native plants in an effort to preserve the original biological habitats. In addition, the biotope that are friendly to people and the environment with a total length of about 450 m, fed by cooling water from the plant, provides an environment for diverse aquatic creatures to flourish, including dragonfly larva, water scorpions, and pygmy water lilies.
Since 2004, we have been supporting the ”Extinct Fish Hemigrammocypris rasborella Revitalization Project” in collaboration with industry, government, academia and the private sector, and have been releasing the freshwater fish ” Hemigrammocypris rasborella2” to promote the conservation of rare species. By reviving endangered species, we are also contributing to raising employee awareness. It is also used for social studies tours and is a place for environmental education.
