Preserving Biodiversity and Sustainable Use

Introducing the Outline of Yamaha Motor Group’s Main Biodiversity Initiatives

Outline of Yamaha Motor’s Main Biodiversity Initiatives


We recognize the importance of preserving biodiversity and other issues related to sustainability, and also that addressing these issues can lead to opportunities for growth.

Yamaha Motor has always attempted to harmonize all of its corporate activities with the global environment, through initiatives including technological innovation in smaller, more environmentally friendly engines, the creation of products such as electrically power assisted bicycles and electric motorcycles that use smart power technologies, and research and development of next-generation power sources.

We have therefore formulated the “Outline of Yamaha Motor’s Main Biodiversity Initiatives” to build on these programs as we address biodiversity.



We will address biodiversity independently, systematically and continuously, based on our corporate philosophy, the Yamaha Motor Group Basic CSR Policy, and the Environmental Plan 2020, from the perspectives of “diversity of ecosystems, biological species, and genes,” “activities that supplement the benefits of nature,” and “minimizing the impact created.”Declaration

  • Contribute with intellectual technologies that respect the earth

    We are deeply aware of the significant benefits of nature on our product fields, and aim to use technology to preserve biodiversity.

  • Pursue activities that are in harmony with the earth’s environment

    We will continue to systematically address biodiversity by cultivating an ecological mindset and taking greater initiative.

    Where biodiversity is threatened, we will promote activities at a global level that protect and foster nature in harmony with the earth’s environment.

  • Make strides in environmental communication and information disclosure

    We will cooperate and work together with broad segments of society in our activities to address biodiversity, and strive to disclose information as appropriate.

Biodiversity Initiatives

We are continuously implementing systematic activities in line with the Outline of Yamaha Motor’s Main Biodiversity Initiatives, based on voluntary participation of employees.

We have been engaged in beach cleanup campaigns since the early 1990s on coasts in Japan and abroad to protect our beautiful and abundant seas. We are carrying on these activities and cultivating an ecological mindset. Some of our specific biodiversity initiatives are introduced below, including efforts to protect the habitats of creatures in danger of extinction.

Protecting the Endangered Loggerhead Sea Turtle

Every year, females of the endangered loggerhead turtle species come to Enshunada Coast, a natural site popular with locals, to lay their eggs.

We have been conducting beach cleanup campaigns at the coast in cooperation with Sanctuary N.P.O. for 27 years starting in 1991. A cumulative total of 12,600 volunteers have participated in these activities, including employees, their families, and friends.

Organizing “Sustainable Beach” Project

We organize cleanup activities to protect the endangered loggerhead sea turtle by collecting garbage that could be an obstacle to egg-laying, scraps of vinyl that could be eaten by mistake, empty plastic bottles or cans, and other litter. We also put down sand-filled cloth bags to prevent sand from blowing away, in order to restore the sandy soil of the beach itself that is essential for laying eggs.

Participating in the 28th Loggerhead Turtle Cleanup Campaign

Employees, their families, and friends continue to participate every year in cleanup activities organized by Hamamatsu City to protect the loggerhead turtle at the Nakatajima Sand Dunes.

Protecting the Endangered Riverside Tiger Beetle

The riverside tiger beetle is an endangered species that was driven from its riverside home by construction of levees and has managed to survive in the Nakatajima Sand Dunes. Since 2015, we have continued to carry out activities twice a year to protect the beetle’s habitat through the removal of alien plant species* in collaboration with the Coastal Control Division of Shizuoka Prefectural Government.

* Alien plant species: Diodia teres, Oenothera laciniata, Lolium perenne, Conyza canadensis

Implementation of Campaign to Remove Alien Plant Species

We carry out campaigns to remove alien plant species with volunteers, focusing on Oenothera laciniata in May and Diodia teres in September, when each species can be most effectively weeded out.

Protecting Nature Around Us

Lake Hamana is one of Shizuoka Prefecture’s cherished natural sites. In order to protect the lake’s nature, shore-cleaning activities are carried out twice a year, mainly by employees from Marine Business Operations.

Organized Marine Cleanup Activities at Lake Hamana

Employees from Marine Business Operations carry out cleanup activities twice a year using products such as personal watercraft and boats to collect trash that has washed onto shore, even in areas that cannot be reached by land.

Coral Reef Conservation Activities

Okinawa Prefecture is said to be home to more than approximately 360 species of coral. However, there are also reports that coral has been diminishing rapidly in recent years both in variety and in number. Alarmed by this situation, a local group launched “Team Tyura Sango,” a public-private joint project to restore the coral reefs.

Yamaha Motor has supported this project since 2007 through measures including volunteer participation in coral planting and financial assistance.

Protecting Rare Species at Test Courses

In order to minimize the impact of our test courses on the natural surroundings, we carry out ongoing initiatives to offset the effect of the courses on the areas around them.

Protecting Rare Plant Species at the Yamaha Motor Kikukawa Test Course

Yamaha Motor is maintaining wildlife diversity and preserving the environment through measures such as protecting areas of existing vegetation and planting trees around the perimeter of the Kikukawa Test Course in Shizuoka Prefecture. In 2008, before the start of construction, the Company conducted a one-year environmental assessment of the site and surrounding area. When the course commenced operations in 2013, we simultaneously began initiatives to preserve rare plant species. Initially, the number of plants declined, but as a result of monthly activities, the number of certain species of plants (Bletilla striata and Penthorum chinense) recovered to an increase in 2016, the third year of the project. We are still protecting the endangered species and near threatened species Cymbidium lancifolium, Cephalanthera falcata, Bletilla striata, Calanthe discolor, and Penthorum chinense through monthly monitoring by employees and with the cooperation of specialists.

Holding Nature Conservation Activities at Various Locations at Our Facilities


The egg-laying of the endangered forest green tree frog is monitored each year at Trail Land Hamakita.


We apply insecticides and plant insect-resistant black pines as measures to combat the pine weevil in the black pines that form a windbreak forest at the Hamaoka Test Course.


We created a pamphlet introducing the seven species of acorn native to the area around the Fukuroi Test Course and distributed it to employees.

Activities that Supplement the Benefits of Nature

We pursue activities to understand and supplement the benefits of nature by carrying out reforestation to supplement the natural beauty of the hilly land that forms part of the scenery of Lake Hamana and participating in Iwata City’s groundwater recharge project.


We aim to create a beautiful bamboo forest in a bamboo grove that has been neglected and become overgrown on hilly land next to the Yamaha Marina Hamana-ko facing the lake. At the same time, we have been carrying out reforestation activities every spring and fall since 2015 to keep the bamboo from invading the broadleaf forest.

Participating in Iwata City’s Groundwater Recharge Project

We carry out Japanese cypress planting and tree thinning in the forest in Iwata City’s northernmost area, a rich source of water. (The area is a “property ward,” a special public body in Japan.)

Protecting Upstream River Areas in National Parks

Group companies in Thailand are pursuing activities aimed at maintaining a balanced ecosystem and mitigating the impact of disasters (measures to prevent flooding by creating erosion-prevention dams) in coordination with the environmental activities of the United Nations.
