Court Affirms Right to Sue U.S. Military Over New Base's Threats to Endangered Okinawa Dugong

Rare Japanese Dugongs One Step Closer to Finally Getting Their Day in Court 

SAN FRANCISCO— The 9th Circuit U.S. Court of Appeals today affirmed the right of American and Japanese conservation groups and Okinawan citizens to sue to compel the U.S. military to fully consider the impacts of a new U.S. military base in Okinawa, Japan. The base would pave over some of the last remaining habitat for endangered Okinawa dugongs, ancient cultural icons for the Okinawan people. The lawsuit is part of a long-running controversy over the expansion of a U.S. Marine air base at Okinawa’s Henoko Bay. Preliminary construction on the base began earlier this year.

After conservation groups and Okinawan community members filed a lawsuit to challenge the U.S. government’s inadequate assessment of the proposed new military base’s impacts on the dugong — including failure to consult with the relevant stakeholders or adequately consider all possible effects on the dugong as required by law — the government argued that the district court could not consider the case because of its foreign-policy implications. The court of appeals today disagreed, holding that the plaintiffs had standing to sue, and that the fact that the case related to a project in another country did not give the government license to ignore the requirements of U.S. law.  The court remanded the case to the district court for further proceedings.

“The court today affirmed the right to sue to prevent the U.S. government from taking action that might harm an endangered species of special importance to people in another country without giving serious consideration to the possible effects of its actions,” said Martin Wagner, managing attorney of Earthjustice’s International Program. “The law is intended to respect the cultural values of the Japanese people, and requires the Defense Department to make every effort to understand and minimize the effects of this project on the dugong.  Today’s decision affirms the right to ask the courts to ensure that the U.S. government complies with this law.”

Dugongs are gentle marine mammals related to manatees that have long been revered by native Okinawans, even celebrated as “sirens” that bring friendly warnings of tsunamis. The dugong is listed as an object of national cultural significance under Japan’s Law for the Protection of Cultural Properties. Under the U.S. National Historic Protection Act and international law, the United States must take into account the effect of its actions and avoid or mitigate any harm to places or things of cultural significance to another country. 

“Our folktales tell us that gods from Niraikanai [afar] come to our islands riding on the backs of dugongs and the dugongs ensure the abundance of food from the sea,” said Takuma Higashionna, an Okinawan scuba-diving guide who is a plaintiff in the lawsuit. “Today, leaving their feeding trails in the construction site, I believe, our dugongs are warning us that this sea will no longer provide us with such abundance if the base is constructed. The U.S. government must realize that the Okinawa dugong is a treasure for Okinawa and for the world.”

"This ruling is a critical lifeline for the highly endangered Okinawa dugong," said Peter Galvin, director of programs at the Center for Biological Diversity. "We are hopeful that an objective review of the project will cause the U.S. Department of Defense to rethink this environmentally and socially disastrous military base expansion plan.”

In 1997, it was estimated that there may have been as few as 50 Okinawa dugongs left in the world; more recent surveys have only been able to conclude that at least three dugongs remain in Okinawa. The Defense Department has authorized construction of the new base, despite the precariously low dugong population estimates.

“Paving coral reefs for a military airbase runway does not make us safer, but more vulnerable to planetary extinction. The Okinawa dugong, sea turtles, coral reefs and the ocean environment are the winners today in this 14-year litigation battle with Department of Defense,” said Todd Steiner, executive director of Turtle Island Restoration Network.  

For years many locals have protested and opposed the base-expansion plan for Okinawa, where 20 percent of the island is already occupied by U.S. military. This lawsuit was originally filed in 2003 by Earthjustice on behalf of the U.S. organizations Center for Biological Diversity and Turtle Island Restoration Network; the Japanese organizations Japan Environmental Lawyers Federation and the Save the Dugong Foundation; and three Japanese individuals. 

MEDIA AVAILABILITY: A delegation from Okinawa — including Hideki Yoshikawa, an Okinawa professor who serves as international director of the Save the Dugong Campaign Center; and Sakurai Kunistoshi, former president of Okinawa University — will be at the Center for Biological Diversity’s office in Oakland (1212 Broadway, Suite 800, Oakland) tomorrow and available for interviews. They will be conducting an informational luncheon program on the case from noon to 1:30 p.m., which journalists are welcome to attend, and are available for interviews before and after the program.
