The Yokohama Port Environment Improvement Contribution Ordinance was enacted in March 1980, and began in April of the same year.

As of March 31, businesses with a total site area of factories or business establishments in the Yokohama Port harbor area and Yokohama Port harbor area of 10,000 square meters or more are required, and notification is required.

Factories and workshops that conduct business activities continuously, warehouses and piles, sites such as offices and parking lots, and occupied water areas are applicable. It does not matter whether it is for-profit or non-profit, or whether it is self-owned.

・Construction or improvement of port environment improvement facilities
・Maintenance of harbor environment improvement facilities

It is a facility for improving the environment of beaches, green spaces, plazas, planting, rest areas and other ports.

This is the ratio of the expenses required for the construction covered by the burden to be paid by businesses. In principle, it is 1/2, but if it is recognized that people other than businesses in the burden area will benefit mainly due to construction covered by the burden, the burden ratio is reduced. .

This applies to the Yokohama Port harbor area and the Yokohama Port harbor area.

(Construction cost subject to burden) x (burden ratio) x (site area of the factory or business establishment of the target company) / (total site area of all factories or business establishments in the burden area)

If there is a green space that is open to the public or if more than 5% of the site area is greened, the area can be reduced.
