The Fuji Oyama Works of Hitachi High-Tech Science (Sunto-gun, Shizuoka Prefecture) has forested land approximately 44,000 m2 in area that has been named the Woodlands of Hitachi High-Tech Science. We have been conducting activities continuously since 2015 with the aim of working as a member of the local community to realize harmony with nature as well as to restore the forest to what it used to be under the traditional satoyama system of managing natural resources in the local environment as a part of the everyday lives of people living there.
We will continue to maintain and regenerate the woodland that takes up 87% of the total area of our premises.
Over the course of some 50 years, we will use plants that are native to the region to broadly transform the present artificial forest of Japanese cedar and Japanese cypress into a broad-leaved forest. We collected acorns from kunugi oak and konara oak trees on the property and cultivated seedlings to plant in a mix with a variety of other trees and return the forest to something more closely resembling its original natural state. The other trees include Japanese snowbell, mountain cherry, Japanese flowering dogwood, and Japanese maple, which are tall and medium-height trees, together with Japanese beautyberry, which is a shrub. Our aim is to restore the natural woodland as quickly as possible. This will also improve the ecology for wildlife such as the great tit (a bird) and the Pallas' Sailer (a butterfly).

Over the course of approximately five years, we will convert a portion of the lawn into a semi-natural zebra grass field full of native grasses. Every around April since 2016, we have been dividing zebra grass roots for replanting.

We are continuously working to eradicate invasive plant species such as Canadian goldenrod and annual fleabane.

Hitachi High-Tech Corporation received the highest rating of AAA under the JHEP certification system of the national organization "Ecosystem Conservation Society - Japan" for the "Woodlands of Hitachi High-Tech Science"(approx. 44,000 m2).
In 2015, Hitachi High-Tech Science's R&D facility became the first R&D facility in Japan to receive an AA+ rank under the JHEP certification system.
Then, continued efforts to preserve and restore biodiversity were evaluated very highly, leading to the "Woodlands of Hitachi High-Tech Science" project being awarded an AAA rating upon renewal every 5 years of the JHEP certification, the highest ranking possible.
The purpose of the "Woodlands of Hitachi High-Tech Science " is the restoration of a rich natural environment where a diverse range of species coexist. We will continue to strive to maintain and preserve biodiversity with our local communities and our employees.
