Yeah, I'm not anti-nuclear, but the attempt to minimize Chernobyl is pretty disgusting. It was a disaster that was dangerously close to an absolute catastrophe.
Man-made catastrophe from the ground up to the point that 7 security and redundancy safety protocols were either forcefully ignored or shut off AND the person in charge of Chernobyl the night of the explosion had no serious training in nuclear power. Then they tried to cover it up for how many days?
You have to wonder how many lives could have been saved if the evacuations would've occurred immediately after the explosion that blew the top of the containment vessel through the roof of the reactor room.
Fact of the matter remains, there are no similarities between Chernobyl and Fukushima, but irrational fear of an outcome similar to Chernobyl is what has the reactors shut down,
currently.

Not an option for Japan at all. They were ramping up nuclear production, not going down, with plans to go to 50% of their power supply with nuclear by 2030.
Based on what this article says here:
http://www.world-nuclear.org/info/inf79.html
Japan had 48.9 gigawatts of capacity in nuclear power. 2 gigawatts in wind already. To replace the 48.9 gigawatts of production, using the largest production turbine that cranks out 6 MW of power per unit and needs at minimum (
http://onlinelibrary.wiley.com/doi/10.1002/we.469/full) a spacing of 6 rotor diameters (413' x 6) you end up with an equation that looks something like this:
48.9x1000= 48900 Megawatts/6MW per turbine= 8150 units
Rotor diameter of 413' x 6 for minimum spacing gives you a circle with a diameter of 2478' or just under a half of a mile. Realistically, you have a dedicated area with a perimeter of 2478' so it takes an area of 1795 square miles to put the farm in.
That's bare minimum. The link I put up that you probably can't access recommends a minimum spacing of 15 blade diameters. That jumps it up to 11,219 square miles since each turbine takes up a square with a perimeter of over a mile now.
Japan is 145,000 square miles. You just used 1.2-7.7% of the total landmass of the entire island nation to put in enough wind turbines to replace the current capacity of nuclear power.
Yes, you could use the sea to base turbines in as well.
No, wind doesn't blow all the time nor does it blow at the optimal speed for the turbines.
In effect, wind is a fall-back supplement that can keep an energy company from having to burn additional coal/LNG/oil. Even as a fall back though, it's well-developed in Japan and you would never likely see production from wind begin able to replace the reliability and scope of production of nuclear power.
That is, reliability until people freak out and demand power plants be shut down without thinking ahead with respect to economics and/or availability.

Separate discussion. Japan's debt/GDP ratio is over 200%, making it either the highest or in the top 3 for sure.
The huge issue with debt in Greece, Italy, Spain? Not even close to that.
Japan has so far financed its debt by borrowing domestically from basically the savings of its population in the national banks.
What that means is that Japan's government gets exceptionally favorable rates to fund it's govt. Problem, they racking up their highest trade deficits in modern history of the nation in part because they're buying tons more oil, gas, and other fossil fuels to keep their country's lights on. That makes their economy all the more shaky. When/if they need to go internationally to borrow more money to fund their gov't the banks they're borrowing from are not going to give them the same favorable rates their getting domestically.
In effect, shutting down the nuclear plants is hurting the country, long term. They shut them down permanently, then the financial crisis that Europe is working through will look like a child's game compared to what happens to Japan when they start having to borrow outside the nation's own banks.
Hell, economists pontificate that Italy is too big to save, and too big to fail. Japan's economy is 60% larger.
The ripples felt in the world markets by the Euro Zone trying to prop up Greece and the problems they had with the logistics and money involved? Japan is 18x larger.
Japan, as a nation, cannot afford to keep running it's electrical grid without nuclear power. Simple economics. Nuclear is 30% cheaper than fossil fuel produced steam:

No, the nuclear power is not the cathartic issue that will trigger Japan's coming recession, but its certainly adding to it for no good reason other than irrational fear.
