Do your research, if you are speculating then pray hard as you buy. They are in deflation for the past decade, so it is a mixed feeling for japan. Government has massive debt, local economy is not expanding or explosive anymore. Their exports are not doing well because of the yen. If rare earth really is viable in japan, then maybe they will have their economy boosted in the future.
Short term, yes. Long term, no. Overall, probably no. They are experiencing slight deflation which means the value of yen 'as cash' is going up over time, at least for a while. Yen's debt to GDP ratio is 200% and with Japanese household savings locked up in Government bonds it is not looking good for their economy. They are in deep trouble because their population is aging fast and there is almost no way to support that population without a detrimental hit to Japan's economy. Shorting the Euro would be more profitable and probably less risky. *these are my views only, not financial advice and may not be correct etc etc
