USD/JPY traded up to 81.11 a short time ago after having officially closed in NY at 80.72. There is an air of clam so far this morning despite earlier news of a fire burning at the No 4 reactor at the Fukushina Daiichi Power station. The Nikkei is up 3.5% in opening trades but futures market is currently in the red. All up look for another messy session. As I write USD/JPY has just dipped back to 80.90 (last 80.95) perhaps tracking the Nikkei futures rather than the physical market.
