Daifuku Group Action Guidelines for Biodiversity

Basic Approach

The Daifuku Group recognizes that addressing biodiversity conservation is an important theme to be addressed in order to create a sustainable society. Under the Daifuku Group Environmental Policy and the Daifuku Environmental Vision 2050, we aim to achieve zero negative impacts on natural capital by implementing specific annual plans based on a medium- to long-term perspective.

Action Guidelines

  • Through systematic training and awareness-raising, all Group executives and employees will gain a better understanding of the sustainable use of ecosystem services and the importance of biodiversity conservation.
  • By referring to international guidelines, we will work to understand and evaluate the impact on biodiversity of all of our business activities, from the procurement of raw materials to the disposal of products.
  • We will comply with laws, regulations, and international rules related to biodiversity conservation, and we will collaborate and cooperate with a diverse range of stakeholders, including governments, NPOs and NGOs, local residents, business partners, and employees.
  • We will minimize negative impacts on biodiversity by reducing CO2 emissions in manufacturing, promoting resource recycling, and reducing hazardous substances.
  • We will consider the ecosystems of the surrounding area in our use of land, and we will implement initiatives at each of our sites that will lead to the conservation of biodiversity.
  • We will make efforts to communicate with stakeholders by actively disclosing information on natural capital as well as information on our biodiversity conservation efforts.

Major Initiatives

The relationship between Daifuku and biodiversity

In order to clarify the relationship between business activities and ecosystems, Daifuku has mapped the interaction of product processes, land use, and other aspects with ecosystems. Based on this map, Daifuku notes the impact on ecosystems by the land use at Shiga Works, which is endowed with abundant nature, and is conducting business activities that take biodiversity into account.

Conservation activities at Shiga Works

In terms of site area, Shiga Works is one of the largest factories in Shiga Prefecture. A survey of ecosystems within Shiga Works confirmed more than 1,000 native species as well as over 70 species of wildlife listed in the Japanese Red List (compiled and maintained by the Ministry of the Environment) and the Shiga Prefecture Red Data Book. In order to preserve this precious natural environment for future generations, we are pursuing various conservation initiatives through the Yui Project*, which promotes communication both within and outside the company.

  • *Yui means “to bring together," and the project is a compilation of various activities that connect water with greenery, people with nature, and people to people.

Results of ecosystems survey (endangered species)

Listed below are the species of wildlife that inhabit or grow within the Shiga Works premises and are classified as endangered in the Japanese Red List 2020.

Threatened - Vulnerable (VU): Species with a high risk of extinction in the wild.

Yui no Mori

As part of the Yui Project, we constructed Yui no Mori (yui means “bring together” and mori means “forest”), which is located within Shiga Works and comprised of conservation ponds, a learning center, and more. It is used as a place for learning within and outside the company, as well as for the biodiversity conservation of plants and animals such as a Japanese red pine forest unique to the region and the rare species of Yamato salamander. In fiscal 2021, we removed dead pine trees and laid woodchips along the Yui no Mori roadside.

Breeding of Yamato salamanders in conservation ponds (artificial ponds)

We are working to preserve the endangered Yamato salamander. To ensure a stable habitat, a conservation pond was constructed in 2014, and we have been relocating larvae and eggs that inhabit the Shiga Works premises since. In fiscal 2021, we confirmed the first spawning and hatching to have occurred in the conservation pond, and we have verified that this happened again in fiscal 2022. Furthermore, since the redevelopment of Shiga Works could lead to a reduced habitat for the Yamato salamander, in fiscal 2023 we created a new habitat in addition to the conservation pond and released larvae into it.

Scarlet dwarf dragonfly habitat preservation

As the wetlands in which scarlet dwarf dragonflies have been confirmed to inhabit will be lost during the redevelopment of Shiga Works, we are working to secure a new habitat for the dragonflies. In fiscal 2023, we created new wetlands using mountain spring water, silver grass, and sedges, and we transferred eggs, larvae, and adult insects to the new area along with plants and topsoil from the existing habitat. We have set up a net about one meter tall so that the dragonflies can settle, and we will continue to observe them.

Creating opportunities for interacting with nature

At Shiga Works, we hold nature observation events with experts so that employees have opportunities to interact with the many plants and animals that inhabit the area. We also hold events such as Christmas wreath making and moss ball making using natural materials procured on site. In fiscal 2023, we are planning to hold nature observation and Christmas wreath making events.

Collaborations with local communities

Participation in the Shiga Green-activity Network’s Biodiversity, Environment, and CSR Research Association


The Biodiversity, Environment, and CSR Research Association is a working group established within the Shiga Green-activity Network, and Daifuku has participated as a founding member since 2015. The association plans and holds seminars and other events for members intended to facilitate learning about the basics of biodiversity, create opportunities to learn about the latest CSR trends centered on the field of biodiversity, and encourage communication between association members.

Participation in the Biodiversity Biwako Network's dragonfly conservation efforts through corporate collaboration

Planning exhibit (Lake Biwa Museum)
Special exhibit (Lake Biwa Museum)

In 2016, neighboring companies* of Shiga Works launched the Biodiversity Biwako Network, which is engaged in biodiversity conservation activities using the 100 dragonfly species confirmed in the prefecture as indicators. The project, entitled Operation Dragonfly 100: Save Shiga's Dragonflies, has three strategies: search for the 100 dragonfly species in Shiga Prefecture, protect them, and educate the public about them. We are also engaged in regular monitoring at the company site, maintenance of biotopes and extermination of invasive alien species, nature observation meetings, exhibitions and presentations of our activities, as well as understanding of the current state of nature in the surrounding area.

  • *Currently, the following six companies are actively involved: Asahi Kasei Corporation, Asahi Kasei Juko Co., Ltd., Sekisui Chemical Co., Ltd., Sekisui Jushi Corporation, Daihatsu Motor Co., Ltd., and Daifuku Co., Ltd.

Blue Ocean Initiative (BOI)

Daifuku has been a supporting member of the Blue Ocean Initiative (BOI), a blue action platform formed by a coalition of corporations, since 2023. The BOI is expanding the scope of its activities to achieve sustainable and effective ocean conservation and prosperity through multifaceted interactions and business co-creation with all stakeholders that have ties with the ocean.

Members of the Osaka Bay Blue Carbon Ecosystem Alliance (MOBA)

Daifuku has endorsed the Osaka Bay Blue Carbon Ecosystem Alliance (MOBA) of Osaka Prefecture since 2024. This Alliance endorses the creation of a blue carbon ecosystem in Osaka Bay in order to realize the Osaka Bay MOBA Link Initiative, which will connect Osaka Bay with a corridor of blue carbon ecosystems (seaweed beds and tidal flats that absorb and store CO2). The Alliance carries out its activities with the cooperation of its members, which consist of companies, organizations, research institutes, and government agencies.

Declaration of Support for Osaka Biodiversity

Osaka Biodiversity

Daifuku Group company Contec Co., Ltd. endorses Osaka Prefecture’s biodiversity preservation activities. In 2023, we submitted a Declaration of Support for Osaka Biodiversity to the Osaka Prefectural Government, and its registration has been approved. This registration system enables the Osaka Prefectural Government to support the efforts of companies and organizations within the prefecture that declare their commitment to actively work toward conserving biodiversity.
