Iida City

Message from the Mayor of Iida City 

Takeshi Sato

In 2007, Iida City declared itself the Environmental and Cultural City. With the aim of creating a city where both people and nature thrive, it has been developing its environmental policies by focusing on the participation of citizens, businesses, and the government.

In 2021, the city council, representing citizens, and the Chamber of Commerce and Industry, representing businesses, jointly issued the Iida 2050 Zero Carbon City Declaration to regenerate lifestyles and the economy through using the environment.

In anticipation of the opening of the Linear Chuo Shinkansen Line, we will continue to collaborate with citizens to achieve harmony between development and the environment, and promote the creation of a vibrant and sustainable region.

Overview of Iida City

Surrounded by the Southern and Central Alps, Iida City is located in the southern part of the Ina Valley. Stretching north to south along the Tenryu River, it is the deepest valley in Japan with a depth of 2,700m. The city is blessed with a lot of nature, beautiful scenery, and a climate that has strong seasonal changes but is easy to live in.

In the past, the city prospered as a major transportation hub between the east, west, north, and south, but has developed economically and culturally in its own way. In preparation for the opening of the Nagano Station of the Linear Central Shinkansen, citizens, businesses, and the government are working together to create the most desirable place to live in Japan.

The Toyama-go (Toyama Valley) of the City was registered as a Minami-Alps Biosphere Reserve (UNESCO Eco Park) in 2014 in recognition of its rich natural heritage and valuable traditional culture and history, including the ‘Shimotsuki Festival’.

Environmental Initiatives 

The city has been working on the utilization of renewable energy in the region since 1914, with the establishment of a small hydroelectric power generation by residents and the establishment of Japan’s first electricity use union. 

In 1996, the city set its sights on becoming an ‘Environmental and Cultural City.’ In 2007, the city pledged to build a city where both people and nature flourish through the active participation and actions of citizens, businesses, and the government. Iida City was the first city in Japan to be declared an environmental city. 

Since 2013, Iida City has been working to return profits to local communities that use renewable energy for public benefit with the introduction of the ‘Sustainable Community Development through the Introduction of Renewable Energy’ ordinance.
