Aichi Prefecture

Message from the Governor of Aichi Prefecture 

Hideaki Ohmura

Aichi Prefecture is the largest manufacturing prefecture in Japan. We have been promoting a variety of environmental measures to also become a top runner in the environmental sector. Aichi Prefecture has the highest installed capacity of residential solar power generation systems, electric vehicles, plug-in hybrid vehicles, and fuel cell vehicles in use in Japan.

In 2020, the United Nations launched the Decade of Action to achieve the SDGs. Aichi Prefecture hopes to become the ‘Environmental Capital of Japan’ by making a significant contribution to achieving the SDGs. The Fifth Aichi Prefecture Environmental Basic Plan, which will guide the prefecture’s environmental policies until 2030, sets out this goal. It aims to achieve the SDGs by using the environment as the driving force for the integrated improvement of the economy and society. It also promotes cooperation and collaboration with local actors through partnerships and develops an understanding and awareness of the SDGs.

Overview of Aichi Prefecture

Aichi Prefecture is located in the centre of Japan. It stretches 106km from east to west and 94km from north to south. With a total area of 5,170 km², it covers about 1.4% of the country. For a prefecture with a large urban area, it has a relatively green and spacious land use and a high percentage of forests and agricultural land. Aichi Prefecture is leading the way in Japan’s industrial development. It is the nation’s leading industrial prefecture in terms of production, especially in the automobile industry. It is also one of the leading agricultural prefectures.

In addition, Aichi Prefecture has hosted three international events: the Aichi Expo, the 10th Conference of the Parties to the Convention on Biological Diversity (COP10), and the UNESCO World Conference on Sustainable Development (ESD). A high level of environmental awareness has subsequently taken root throughout the region.

Environmental Initiatives 

To solve multiple issues in an integrated manner, Aichi Prefecture is prioritizing promoting measures that contribute to achieving the SDGs. The aim of the ‘Environmental Capital Aichi’ is for social and economic improvements to be integrated with environmental improvements. The plan will be the driving force to achieving the SDGs in Aichi Prefecture.

To actively contribute to the achievement of the ‘Aichi Targets’ adopted at COP10, Aichi Prefecture established the ‘Group of Leading Subnational Governments toward Aichi Biodiversity Targets (GoLS)’ in 2016 with state and prefecture-level regional governments around the world that are making advanced efforts in biodiversity conservation, and has encouraged the activation of initiatives by local governments around the world.

On the occasion of the adoption of the new Kunming-Montreal Global Biodiversity Framework at COP15 in December 2022, the GoLS has changed its name to ‘Group of Leading Subnational Governments toward Global Biodiversity Targets’, and it continues to work with ICLEI and other local government groups worldwide to actively conserve biodiversity conservation activities to achieve the new framework.
