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.

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)

Adult Yamato salamander
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 the larvae and eggs that inhabit the Shiga Works premises since. We have also confirmed spawning and hatching in the conservation pond every year since fiscal 2021. In addition, there is a risk that the redevelopment of Shiga Works could lead to a reduced habitat for wild Yamato salamanders. To combat this, we are implementing ongoing initiatives in fiscal 2024 to maintain and improve their natural habitat, including creating a new habitat outside of the conservation pond into which larvae will be released.
Conserved Area Certification
Conserved Area Certification
In September 2024, Yui no Mori was certified as a conserved area by the Ministry of Environment, Government of Japan. This is a site certification system in which the Ministry of Environment certifies areas where biodiversity is being conserved through private or other initiatives. This certification system was launched in 2023 in order to achieve the international target of conserving the ecosystems of at least 30% of land and sea areas by 2030 (known as the 30by30 target).
Scarlet dwarf dragonfly habitat preservation

New wetlands
Transfer of adult insects
As part of 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 while minimizing this loss. In fiscal 2023, we created new wetlands using mountain spring water, silver grass, and sedges, and we transferred eggs, larvae, and adult insects to this new area along with hydrophytes and aquatic plants from the existing habitat. We also set up a net about one meter tall to enclose the wetlands. The plants that were transferred here are flourishing, and it has become an environment in which the dragonflies can settle easily. In fiscal 2024, we conducted a habitat survey in the newly created wetlands, and we confirmed that adult scarlet dwarf dragonflies are inhabiting the area.
Creating opportunities to interact 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 using natural materials procured on site.
Conservation activities at global subsidiaries
Daifuku Intralogistics India Private Limited (ILIN) has been making efforts in biodiversity conservation for over ten years through the planting of trees. By actively planting native plants that are well-suited to the local climate and soil, ILIN is contributing to the conservation of the local ecosystem while also creating a pleasant working environment surrounded by greenery.
Collaborations with local communities
Participation in the Biodiversity Biwako Network’s dragonfly conservation efforts through corporate collaboration
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 five companies are actively involved: Asahi Kasei Corporation; Asahi Kasei Juko 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
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.
