The Ichijima Factory has proactively worked to develop a mixed forest comprising both coniferous trees and broadleaf trees from the perspective of protecting biodiversity, to this end carefully conserving a native forest that exists on its premises. At the same time, the factory has been active in protecting rare species living on its premises. For example, its efforts to nurture great purple emperor (Sasakia charonda) butterflies date back to 2007, when staff began to cultivate Chinese hackberry (Celtis sinensis) trees to feed the butterfly’s larvae. In 2011, staff then manufactured a cage to protect the pupae until emergence. Once the butterflies began breeding successfully, the factory started to invite children from neighboring kindergartens to observe them every year. In addition, the factory’s premises have been approved by the local government as a habitat area for Lefua echigonia (Cobitidae family), a class I endangered species of loach fish, for
risk dispersion. Based on this approval, the factory is engaged in the protection and nurturing of this species, employing a biotope developed within its premises.

In autumn, the factory makes its premises open to kindergarteners so that they can enjoy acorn gathering. As such, the factory has also been active in facilitating interaction with fellow community members and promoting environmental education via the use of greenery. These efforts, in turn, helped the Ichijima Factory garner outstanding recognition and be chosen for the above award.
