Golden Week: Yokohama, Nikko and exploring Tochigi-ken

Since the big earthquake, tsunami and nuclear power plant incidents, tourists have been avoiding anywhere north of Tokyo like the plague. Perhaps it's the media's fault; their addiction to sensationalism overriding any pangs of guilt for causing unecessary panic. Perhaps it's down to the embassies advising against non-essential travel to anywhere north of the capital. Perhaps people are generally just keeping on the safe side, and don't know what to expect.
 
Well, I visited Yokohama, the second largest city in Japan, a few train stops before Tokyo (from Hamamatsu) and then I visited Nikko, a three hour train ride north of there. Neither were disaster zones, and even the "blackouts" didn't extend to more than a slightly inconvenient train schedule and a few escalators turned off. It seems that some places are making only a token effort to close down electricity, perhaps turning off one or two lights while most things go on as normal. Nikko is in Tochigi prefecture; the prefecture just next to (south-west of) Fukushima. Does this strike fear into your hearts? I'll tell you about it, and you can decide what you think.
