Nagano Prefecture

Message from the Governor of Nagano Prefecture

Shuichi Abe

The progression of global climate change is having a significant impact on our daily lives by increasing the number and scale of natural disasters and changing the distribution areas of plants and animals. In addition, the rapid decrease in population that is expected in the future will lead to a shortage of people to support local communities, including environmental conservation, and there are concerns about the decline in local vitality. Against this backdrop, I am convinced that Nagano Prefecture, with its beautiful and rich natural environment, its unique traditions and culture, and its strong regional ties, can be a frontrunner in building a new sustainable society. 

In 2017, Japan’s Ministry of the Environment, ICLEI, and Nagano Prefecture collaborated to hold Japan’s first International Conference on Local Renewable Energy in Nagano Prefecture. As a result of the conference, the Nagano Declaration by Local Government Leaders Aiming for a 100% Renewable Energy Region was issued.

In 2019, the G20 Ministerial Meeting on Energy Transformation for Sustainable Growth and the Global Environment was held in Karuizawa, a town with a rich track record of hosting international conferences. On the occasion of this meeting, we have compiled the ‘Nagano Declaration on Collaboration for the Development of a Sustainable Society’ together with ICLEI, and are calling for the support of local governments around the world. We will continue to strive for the realization of a sustainable society through partnerships with ICLEI and all other actors. 

Overview of Nagano Prefecture

Nagano Prefecture, located in the centre of the Japanese archipelago, has an area of 13,561.56 km2 and is the fourth largest of the 47 prefectures after Hokkaido, Iwate, and Fukushima. It is one of the most mountainous prefectures in Japan, blessed with a rich natural environment, with a series of 3,000-meter-high mountains bordering eight prefectures and large rivers such as the Chikuma, Kiso, and Tenryu Rivers flowing out of the mountains. 

Nagano Prefecture hosted the 1998 Winter Olympics and Paralympics, and became known for the international Nagano Snow Resort. Even today, many skiers from overseas visit Nagano to enjoy the magnificent mountain scenery and the world’s best powder snow.

Environmental Initiatives 

The Sustainable Development Goals (SDGs), which aim to solve economic, social, and environmental issues in an integrated manner, have begun to be implemented in Japan and overseas. In March 2018, Nagano Prefecture formulated the Fourth Nagano Prefecture Environmental Basic Plan with the basic policy of promoting measures based on the SDGs, and in June of the same year, Nagano was also selected as ‘SDGs Future City’.

In June 2021, the ‘Nagano Prefecture Zero Carbon Strategy – Actions until 2030 to achieve 2050 Zero Carbon’ was formulated, setting a high target of ‘reducing net greenhouse gas emissions by 60% by 2030’ to achieve zero carbon by 2050.

In November 2023, the Nagano Prefecture Zero Carbon Strategy Roadmap was formulated as a scenario for achieving the 2030 target set out in the strategy. In the future, Nagano Prefecture will continue to promote not only environmental conservation but also efforts to solve economic and social issues by utilizing the environment.
