Narrow Road Widening and Improvement Project

Updated: June 3, 2024

Roads in our neighborhood are one of the most important facilities for our lives. In particular, roads in daily life are not just for passage, but also play an important role in ensuring sunlight and ventilation, protecting a comfortable living environment, and serving as evacuation routes in the event of a disaster.

However, in Inagi City, there are many narrow residential roads with a width of less than 4 meters, so-called "narrow roads." Narrow roads are not only dangerous for people and cars, and bicycles and cars, but also pose a major obstacle to the passage of emergency vehicles and firefighting activities in the event of an emergency.

Therefore, in order to eliminate these narrow roads and create a better living environment, the city has been carrying out the Narrow Road Widening and Improvement Project since fiscal 1991.

We ask for your understanding and cooperation in order to promote the creation of a safe, comfortable, and people-friendly city.


Narrow Road Widening and Improvement Project Implementation Status

Business target

A site adjacent to a road designated by a specific administrative agency pursuant to Article 42, Paragraph 2 of the Building Standards Act and a road whose route has been approved by the city pursuant to Article 8, Paragraph 1 of the Road Act.

Note: For information regarding Building Standards Act specifications, please contact the Tama Building Guidance Office.
Note: For route certification, please inquire at the Management Division of the Urban Construction Department of Inagi City (3rd floor of City Hall).

Business content

If you donate or lend the land free of charge, the city will develop it as a road (pavement, drainage facilities, etc.) and maintain it. In addition, the city will subsidize part of the cost of relocating or demolishing properties on setback land or corner cutting land. If you donate the corner cutting land, we will provide a subsidy.

Note: By agreeing to use the setback land and corner cutting land as public roads and submitting the necessary documents, such as a free loan application form, you will be eligible for a reduction in fixed asset tax and city planning tax.
