I believe Japan will be forced to vacate Tokyo due to Fukushima exposed spent fuel rods.

22. Japan Has No Plan to Halt U.S. Beef Imports on Mad-Cow Case

http://www.bloomberg.com/news/2012-04-25/japan-has-no-plan-to-halt-u-s-beef-imports-on-mad-cow-case-1-.html

Japan won’t suspend U.S. beef imports even after the discovery of mad-cow disease in California, said an agriculture ministry official.

“We are importing beef from the U.S. under rules agreed between the two nations, based on the assumption that mad-cow disease has not yet been eradicated,” Minoru Yamamoto, director at the ministry’s international animal health affairs office, said today by phone. “We don’t plan to halt imports because of the discovery in the U.S.”

The first U.S. case of the brain-wasting disease in six years was found in a dairy cow before it entered the food chain and posed any threat to consumers, John Clifford, the U.S. Department of Agriculture’s chief veterinarian, told reporters yesterday in Washington. The cow was identified as part of routine testing for the disease, Clifford said.

Japan restricts U.S. beef imports to cattle 20 months old or younger as older animals are at higher risk of having the disease. The regulation was put in place before Japan resumed purchases in 2005 of American beef, which had been banned after of the first discovery of the disease in the U.S. in 2003.

Transfer of US Troops Out of Japan Hardly a Withdrawal
http://news.antiwar.com/2012/04/27/transfer-of-us-troops-out-of-japan-hardly-a-withdrawal/

The U.S. and Japan have come to an agreement on the relocation of about 9,000 U.S. Marines that will leave their bases in Okinawa, with about 5,000 transferred to Guam and the rest spread among other locations in the region.


US military bases in Japan, Wiki
Contrary to the narrative in the media, the closure of five bases and transfer of 9,000 troops off the Japanese island of Okinawa is not anything like a withdrawal or a drastic pullout. There will still be 9 bases and 17,000 marines remaining on the island and over 30,000 U.S. troops in Japan overall.

Up to 85% of the Okinawan population wants U.S. troops out. Not only do they not want to be occupied by a foreign military, but they’re fed up with the outrageous behavior of the American Marines. Between 1972 and 2009, there were 5,634 criminal offenses committed by US servicemen, including 25 murders, 385 burglaries, 25 arsons, 127 rapes, 306 assaults and 2,827 thefts.

The newly announced plan is part of an agreement from 2006, when the U.S. and Japan agreed to transfer 8,000 U.S. Marines from Okinawa to the island of Guam and to relocate the Futenma Air Station to another part of Okinawa. The plan stalled for years due to resistance from Okinawans who would not agree to the new location of the airbase.
