The Advantest Group's Guidelines of Action for Biodiversity

To show our gratitude for the gift of nature that is endowed by biodiversity, and to recognize the significance of biodiversity in underpinning the prosperity and the wellness of our society, the Advantest Group will carry out initiatives in conserving biodiversity and in contributing to the sustainable use of biological resources.

  1. Understanding Environmental Impact
    We identify, evaluate and share information on any aspects that may have a significant impact on biodiversity in the entire lifecycle of our business activities.
  2. Understanding Biodiversity
    We increase awareness and understanding of biodiversity among all employees so that they are able to engage in activities that give consideration to biodiversity in their business activities and daily lives.
  3. Reduction of Environmental Impact
    By seeking highly effective measures, and by carrying them out continuously, we reduce the impact of our business activities on biodiversity.
  4. Cooperation with Stakeholders
    We cooperate with a variety of stakeholders such as the government, educational organizations, NPOs, local residents and our business partners to promote activities related to the conservation of biodiversity.

Reflecting our commitment to living in harmony with nature, in 2001 Advantest established a biotope eco-park in Gunma R&D Center, with the aim of helping to recreate the original, natural landscape of the Kanto Plain, a landscape that is being lost to development; this biotope is the largest of its kind established by any private-sector company in Japan.

Advantest's biotope provides a venue in which Advantest employees can learn about the importance of protecting the global environment; the biotope is also used as a means of fostering communication with local residents. About 20 years have passed since the establishment, and the biotope now has an optimal environment for preserving the local ecological system and is playing a great role in protecting and growing threatened species. In addition, Advantest's biotope provides an ideal environment for achieving an SDG target, "15 LIFE ON LAND".

∗ Biotope: The word comes from the German words "bio" (living organisms) and "tope" (a location).

Floating heartFloating heart

At the biotope in the Gunma R&D Center, Advantest has been exploring and protecting animals and plants, growing plants, and getting rid of alien species under the guidance of Gunma University since 2001. Advantest is also protecting and growing boneset and floating heart, which have been designated as near threatened species by the national government and as threatened species (IA) by the Gunma Prefecture.

With regard to boneset, there are only five places where it grows naturally in Gunma Prefecture, one of which is Advantest's biotope. Advantest has been continuing these protection and growth activities for many years, which has led to the realization of an environment that enables the stable natural growth of boneset.

With regard to floating heart, there is only one place where floating heart grows naturally in Gunma Prefecture, and Advantest's biotope has been used as an evacuation shelter since 2012, where floating heart grows steadily.

Hosting of Nature Observation Events in the Biotope


Since 2005, Advantest has been holding nature observation events for elementary schools located near its sites, using the biotope as a venue for communicating with surrounding communities. Participants in these events learn what kinds of plants and animals live in the biotope by conducting a search. They also fish for crayfish to reduce the number of non-native species such as American crayfish, which encourages them to consider the importance of biodiversity. In fiscal 2018, about 100 children and parents from two neighboring elementary schools took part in our nature observation event. We plan to continue this activity, making it a centerpiece of cooperation with the community.

Conservation Activity to Protect Japanese Red Pine Trees at the Advantest Laboratories



Within the grounds of the Advantest Laboratories Ltd. facility (in Sendai City, Japan), there are approximately 80 naturally-growing Japanese red pine trees, which are about 100 years old and grow to a height of around 30 meters.
This Japanese red pine grove was designated a Protected Forest by Sendai City Government in 2007. To help ensure the maintenance of a rich natural environment, Advantest is working to conserve these Japanese red pine trees and the creatures that live in and around them.

Forest Conservation Activity in the Kusatsu Therapy Forest and national forests of Mt. Akagi



Forest conservation activity and participants

Every year since 2007, Advantest has been conducting forest conservation activities. Up until 2017, Advantest had been conducting the activities in the national forests of the "Kusatsu Therapy Forest" in Gunma Prefecture. Since 2018, Advantest has been pruning and conducting other activities in the national forests of Mt. Akagi to restore healthy forests. Through these activities, Advantest has raised the environmental awareness of its employees, thereby contributing to forest degradation prevention and water resources preservation. These conservation activities also contribute to the absorption of CO2 by forests.

Environmental Impact Assessment

Advantest records and assesses the environmental burden on the area surrounding its business establishments in accordance with ordinances and pollution control agreements.
In addition, we are managing plants and cultivating biotope at our business establishments while considering biodiversity.
