I'm Japanese, so I can tell new information from Japan.
I was watching the TV news from 07:00 this morning.
FedEx 80 was trying to land RWY34L of NRT, then 21m/s wind from northwest, and also was windshear.
Windshear was reported by the airplane that landed on before FedEx, and ATC told the information about windshear to FedEx.
Judging from the picture of the television, the cockpit was crashed so hard when lying on its back.
I think the plane was in flame for 60 min or so.
and some photos here.
