This is going to have massive effects on the Japanese economy for the coming years, remember that the Japanese economy was in a pretty dire state before the event.
Japan will see electricity shortages (also, it's going to be a hell of a lot harder for Japan to build new nuclear plants in the future, due to local opposition... which has its own problems, as Japan will be forced to stick with more fossil fuels, which, of course, have ever-rising prices), the supply chain has been completely ruined, billions of corporate and consumer assets have been lost, massive destruction to infra-structure, not to mention the loss of life - not to be cold, but each working life lost results in slightly less work in the economy.
And the worst could yet to come - if there is any major radiation leak, it could render parts of Japans already limited space completely uninhabitable for many, many years.
