If I understood correctly, I believe that the last refugee shelter was closed on December 28th. Never the less, 350,000 people are living in temporary shelters. A lot of these communities are made up of residents from many different areas, so they are being encouraged to make bonds with their new neighbors.
After the quake many volunteers came to the affected areas to help the locals rebuild. Since then the number of volunteers has dropped quite a bit, but there are still people coming to help those in need. I just saw some footage of people helping a farmer pick plastic, glass and other bits of debris from his crop land.
The number of self defence force personnel being deployed has been reduced as well. This has worried some communities that have lost of lot of manpower for labor and police forces.
Work continues to clean up the Fukushima nuclear reactors. After the accident, there was talk of a "cold shutdown" planned to take place within the first nine months. That may have been achieved already, but at that time no one knew how badly the reactor cores had melted down. Last news I heard was for a 30 to 40 year plan to clean up the reactor cores. But this too is probably only a guess since it is not known yet how the core material will be disposed of. Not only that, the technology to do this does not even exist and needs to be developed. The following is a newspaper diagram explaining a proposed method of extracting the core material...

The most recent side effect of this disaster regards construction companies who unknowingly used concrete making ingredients which had been polluted with radiation. This has caused some streets and buildings to have been constructed with radioactive materials. Last I heard, this investigation is still under way, but residents in some of these places have been relocated. It sounds like last May there was a proposal for a government regulation on the radiation levels in construction materials, but somehow this regulation was never created.
There was one other unexpected occurrence related to the nuclear disaster. Because of the fear of radiation, many people started carrying around their own radiation detectors. There were actually a few incidents of people finding radioactive hot spots that were totally unrelated to the Fukushima disaster.
That's all I can think of to report on for this year. Happy New Year and lets hope for the best as Japan continues to rebuild in 2012.
