Japan has been very open with the radiation levels. Tokyo is about four hours south of Fukushima, and while they have noticed a slight increase in radiation, it's very slight. The level in Tokyo now is reported to be 0.8184 micro-grays over a 24 hour period. Thus, if you spent 4,686.72 years in Tokyo at this level, you would accumulate the same amount of radiation as getting a single X-ray.
