Supreme Court Ruling Stops Awase Tideland Reclamation Project, Okinawa Prefecture - December 2001

Awase Tidal Flat, located in central Okinawa Prefecture, forms an important ecosystem that is home to rare plants and animals from Japan and abroad. However, the reclamation plan that had been underway since the 1990s had caused serious ecological destruction. The plan was intended to develop port facilities and commercial areas, and was supposed to revitalize the local economy. However, many objections were raised due to inadequate environmental impact assessments and the negative impact on biodiversity.

Endangered species such as the mussel and horseshoe crab inhabit the tidal flats, and the installation of the anti-pollution membrane was found to have a negative impact on the seafloor environment. Citizens' groups and environmental groups called for the cancellation of the plan and appealed for a field survey to be conducted. The Awase Tidal Flat has attracted international attention as a candidate for registration under the Ramsar Convention, and the reclamation plan has become a symbolic case that calls into question the state of Japan's environmental policy.

Conclusion of the Plan
In 2010, the Supreme Court ruled that the Awase Tidal Flat reclamation project "lacked economic rationality," and Okinawa Prefecture and Okinawa City decided to cancel the project. As a result, a certain degree of preservation of the natural environment of Awase Tidal Flat has been secured, but there are still issues surrounding the balance between environmental protection and regional development. Citizens' groups and environmental groups continue to call for the preservation of the tideland.
