The Environment Agency will create a database of tidelands in Japan, making records on topography and fauna over a five-year period to protect those sites, agency officials said Tuesday.

The agency has included an appropriation of 100 million yen for the project in its budgetary request for fiscal 2001, the officials said.

Under the project, which will cover 1,500 tidelands across Japan and incorporate data from private-sector and historical materials, agency officials will inspect some 120 of the 1,500 tidelands and release the acquired data on the agency's Web site, they said.
