Japan is increasing coal-based power generation (coal sourced mostly from Australia, but some from China), and I have no doubt that Japan is increasing petroleum consumption to compensate for loss of nearly 20% of their electricity-generating capacity. This is one of the reasons why the price of oil has remained stubbornly high despite a massive global economic slowdown.
These are not without consequences. The negative effects of burning coal are well understood, and increased reliance on oil will cause even more rapid depletion of already depleted oil reserves (not to mention increased dependence on atavistic, tribal dictatorships), bringing us closer to predicted disruptions due to peak oil.
The good side of this is that people are learning to live with less, and producers of consumer goods are developing ever more efficient appliances. Hopefully this will also spur Japan to establish a sort of "Manhattan Project" for renewable/green energy, whereby they can emerge nuclear-free and less reliant on oil producing regimes. But in the short term, there are threats of power shortages, and Japan is bringing decomissioned coal-fired plants back online. You can check daily projected power consumption at this site
