The ministry asks the developer to specify post-construction monitoring, including underwater-noise propagation during operation and rapid detection of possible migratory-bird collisions. If serious effects are identified, additional conservation measures should be considered with expert advice.

The proposed site off Niigata Prefecture covers about 9,242 hectares. The opinion is not an operating approval: the developer must still prepare the final environmental assessment document taking national and local opinions into account.
