Okinawa Prefecture in southwestern Japan has filed a lawsuit to demand the cancellation of a decision by the land minister over a landfill project related to the relocation of a US base.
The ongoing landfill work is part of a plan to relocate the US Marine Corps Futenma Air Station in Ginowan City to the less-populated Henoko district of Nago City.
The prefecture filed the lawsuit with the Naha branch of the Fukuoka High Court on Friday. The lawsuit demands the cancellation of the decision that the land minister made last October to suspend the prefecture's retraction of the approval for the landfill work.
Landfill work began following the suspension decision.
On Tuesday, Okinawa Governor Denny Tamaki asked Prime Minister Shinzo Abe to suspend the work to allow time for negotiations on the relocation project that was opposed by a majority of eligible voters in the recent prefectural referendum.
Tamaki indicated that he hopes to solve the issue through dialogue.
The central government says it has told the prefecture that the landfill work will continue as scheduled, adding that dumping rocks and sand in a new area off Henoko will begin as early as next Monday.
