[...] The main body of radioactive surface plume of which activity exceeded 10 Bq m−3 travelled along 40° N and reached the International Date Line on March 2012, one year after the accident. A distinct feature of the radioactive plume was that it stayed confined along 40° N when the plume reached the International Date Line. [...]
A distinct feature of the radioactive plume was that it stayed confined along 40 N when the plume reached the International Date Line, as stated in Sect. 3.2. The radioactive plume travelled 1800 km (from 160 E to 178 E) for 270 days (9 months) (Fig. 5); therefore, an average zonal speed (u) of the surface radioactive plume was calculated to be about 8 cm s−1 which was consistent with the speed of the reported surface current of 4–16 cm s−1 in the region (Maximenko et al., 2009). [...]
We can also assume that the Fukushima radioactive plume moved with surface water [...]

Is Japan Responsible for damages in an american court?

I spoke to a Nuclear Tech for the guys that have lots of boats in the ocean there you can guess who that is. He said that there is not much we should worry about because if something did happen they would never let the smartest people a superpower has "chill" in the area. He was there literally scanning entire fields of grass just for tiny tiny tiny amounts of radioactive material. In his conclusion if you are worried about the damage from the disaster you might as well never see the sun again or eat a banana again because it will damage you more long term. Just saying from what he told me. We have learned a lot from what happened just like every other disaster. I was scared about the fall out too but the way he put it put me at ease and he seemed like a straight shooter.
You're welcome. I think it's sound, as I'm a former radiation worker so I've had training in this stuff. But the truth is, we don't really know how many people will die as a result of the Fukushima disaster. I think if there's any concern it would be greatest for Japanese schoolchildren living in contaminated areas since children are thought to have greater susceptibility to radiation damage (as they are still growing). One Japanese official quit his post in protest over how high Japan regulators set the limits of radiation that schoolchildren could be exposed to after the disaster.

Thanks for your input it is seems like it is sound in regards to what happened.
The plume is not visible so there's no way to photograph it.

Anyone have any photos of it?, that would pretty insanely awesome.
The majority of premature deaths caused by Chernobyl are expected to be the result of cancers and other diseases induced by radiation in the decades after the event. This will be the result of a large population (some studies have considered the entire population of Europe) exposed to relatively low doses of radiation increasing the risk of cancer across that population. Interpretations of the current health state of exposed populations vary. Therefore, estimates of the ultimate human impact of the disaster have relied on numerical models of the effects of radiation on health. Furthermore, the effects of low-level radiation on human health are not well understood, and so the models used, notably the linear no threshold model, are open to question.
Given these factors, studies of Chernobyl's health effects have come up with different conclusions and are the subject of scientific and political controversy.
No statistically significant increase in major birth defects or other untoward pregnancy outcomes was seen among children of survivors.
