@  SlyCooperFan1Well, I checked the Japanese Wikipedia article of Joint Assault, it says "since the Tokyo Sky Tree is completed, it's assumed the time is after early spring of 2012, however, since the fourth runway of Tokyo International Airport is not seen, so it's also assumed to be earlier than October 21st 2010, there's no anwser".

Original text "東京スカイツリーが完成している所を見ると2012年早春以降と考えられるが、東京国際空港の4本目の滑走路が描かれていないことを考えると2010年10月21日以前となり、不可解である".
