ken, I am really curious about how you managed to get anything "radical" or "communist" out of the Japan Times. Click-bait sure, sensationalist yeah, and I'll even give you "anti-government" if you want, but I'd really like to see the articles where they're advocating socialism.
If you do want news from a communist perspective, I recommend you go to the horse's mouth:
http://www.japan-press.co.jp/Anyway, to help the OP out, here are some links:
The Sendai International Relations Association (SIRA), which maintains a nice space with lots of information and a multi-language library in the International Center there:
http://www.sira.or.jp/english/index.htmlThe "Life in Sendai" guide, which has lots of basic information, including what do in the even of a disaster:
http://www.sira.or.jp/english/foreigner/And the "Sendai at a Glance" guide, which has a lot more detailed information on specific doctor's offices, places to have fun, etc.:
http://www.group-niji.org/index.htmlAnd to answer your questions:
They are not distributing anti-radiation pills. However, the nearby Onagawa nuclear plant (operated by Tohoku Electric Power), which suffered no damage in the disaster, could possibly restart within the next two years.
There is no bubble to burst, as Japan has experienced only slow, and most likely sustainable growth in recent decades. The effects (if any) of "Abenomics" are still unclear, and most likely will remain so in two years time, but they certainly haven't caused rapid economic growth that could possibly be leading up to a bubble.
People in Sendai are seen as people. The city itself is probably considered a bit out in the boonies for the people of Tokyo, but within Tohoku it is the major city and happening place.
If you find yourself distressed SIRA offers quite a lot of support and contacts. They may be able to set you up with a counselor, etc. who could help you with your problems.
There are quite a lot of foreigners in Sendai. Having good transport links it is a mildly popular tourist destination, as a large city there are a fair number of foreign English teachers, and with a large number of universities there are quite a lot of foreign students living in the city.
