From what I hear Japan doesn't have a good social safety net. See eg. http://www.nytimes.com/2009/02/08/world/asia/08japan.html?pa... I would be happy to be wrong and the situation might have improved very recently?
That's an interesting article about how Japan hadn't yet extended their safety net (which includes things like universal health care) to the emerging edge case of mass layoffs, something that just didn't happen in their culture before.
Sounds like a third of the workforce is at risk of homelessness any time their temp runs out and this has been developing for ~ 15 years.
