Tokyo : So far the only good news to accompany the Fukushima catastrophe has been that for all the fallout, the radiation has been mostly contained due to Northwesterly winds which have been blowing any radioactivity mostly out and into the Pacific (coupled with relatively little rainfall), as well as the dispersion of irradiated cooling water which promptly enters the Pacific after which it is never heard of or seen again (there is at least a several year period before 3 eyed tuna fish feature prominently in restaurants across the country).
