Some excellent blogposts on Japan's problems via Economonitor:
1) All exports and money printing can't offset Japan's debt, ageing and domestic demand woes: http://www.economonitor.com/edwardhugh/2013/02/12/japans-looming-singularity/?utm_source=contactology&utm_medium=email&utm_campaign=EconoMonitor%20Highlights%3A%20End%20Games
2) Does end of growth (Japan's example) spell end of high quality of life? http://www.economonitor.com/dolanecon/2013/02/15/growth-and-quality-of-life-what-can-we-learn-from-japan/
3) Japan's forgotten (but not fully unwound) debt bubble: http://www.economonitor.com/blog/2013/01/the-setting-sun-japans-forgotten-debt-problems/
All worth a read.
I can add that in 2011 Quality of Life Index by International Living magazine, ranking 191 countries around the world, Japan was in 7th place (rank range is between 7th and 10th), whilst Ireland was in 20th (rank range between 20th and 26th) in terms of overall quality of life, with Japan outperforming Ireland in 4 out of 9 categories of parameters on which the rankings were based and tying Ireland in one category.

Note: the above rankings did throw some strange results, so careful reading into them.
