It mostly consists of sticking their head in the sand and pretending the problems don't exist. :-)

Not really, but it seems that way sometimes. The overall plan is called "Abenomics", named after the current prime minister who put the plan together. The Council on Foreign Relations does a decent job on covering the major points and has a good additional resource list to boot.

In short, though, it's a three pronged approach. There was a stimulus package, which really didn't stimulate much, quantitative easing with a target of 2% inflation, which has only caused small bumps of inflation followed by more deflation and increases in public debt, and structural reforms, for which there is little real political appetite.

There have also been some laughable attempts to attract more foreign skilled workers, but again, there's little political will to fix the issue. Honestly, at this point, I don't know if even a massive wave of immigration would be enough to save the country. They should have been focusing on small groups that could be integrated into society starting decades ago, but foreigners are still the big scary other in Japan. This is despite the rather low occurance of foreign crime there.

In summary, too little, too late and without the political or social will to really make much of a difference at this point.
