A Japan-U.S. working-level group of experts will provide two options for relocating U.S. Marine Corps Air Station Futenma to Camp Schwab in Nago's Henoko district, a draft report showed Sunday.

With two key Okinawa elections scheduled for September and November, the government of Prime Minister Naoto Kan has decided to shelve the runway issue until after the polls, sources said earlier.

Both plans aim to achieve the task by reclaiming waters off the coast of Henoko, but one calls for two runways in a V-shaped formation while the other envisages the building of a single runway, an option expected to reduce the need for reclaimed land by 25 percent, the draft says.
