Because the wind blew to the sea instead of mainland japan.

  Hi, so, I was actually deployed to Japan and discussed the wind predictions with the modelers at Lawrence Livermore who ran the simulations and I saw the isotope sampling data collected from the planes flying through the atmosphere over Fukushima. Getting a re-entrant flow for enough time get any meaningful amount of radiation over any populated area was never going to happen. Like, ever. Like, they seemed really apologetic for having ever run the simulations, but the question national leadership posed was "how long would you need re-entrant flow to get significant exposure?" So they had to sustain an irrational model until they got a time. And based on that we spent a huge chunk of Operation Tomadochi's $90M on keeping sealift resources on standby off the coast in case of a Vietnam-style evacuation.
