Conservation of Green Spaces

  • We carefully manage green spaces at each of our offices. On the Katsuta Plant premises, we grow about 1,700 evergreen and deciduous trees, including 600 cherry trees, around the buildings while preserving natural forests that attract various insects, wild birds, and small animals. We also replace old trees with young trees as planned. In fiscal year 2019, we replanted 24 trees.

Undertaking of Vegetation Surveys

We’ve conducted nature conservation activities whatever possible such as management of trees and bird watching on our premises.
We recognize the significance of the "biodiversity and ecosystem conservation activities" to further develop ourselves as a company, and promote them by establishing the "environmental policies" and the "guidelines related to conservation of biodiversity".
In the first stage, we conducted a vegetation survey of a natural forest and a nature conservation area within the premises of our plants. The survey revealed 52 kinds of plants at Katsuta Plant, and 20 at Sawa Plant.
We are committed to carrying out further field surveys and conservation activities.
We will also raise awareness of our employees, and participate in local environmental conservation activities.

Control of Invasive Nonnative Species (Lanceleaf Tickseed)

  • In the City of Hitachinaka, there are many areas where lanceleaf tickseeds, which are invasive species, grow.
    Invasive species are species which have been introduced to areas outside their original habitats and threaten biodiversity as identified by the government. It is prohibited to grow, store, import, transport or raise them.
    We’ve participated in the extermination activity campaign of lanceleaf tickseeds hosted by the association aiming to improve the environment of Hitachinaka since fiscal year 2017. We will participate in extermination activities of invasive species wherever possible.
