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.

"the number of nonregular workers took off after an easing of labor laws in 1999" .. "To receive unemployment insurance, for instance, workers must have held the same job for at least a year, effectively excluding most temporary workers" .. "Today, 34.5 percent of Japan’s 55.3 million workers are nonregular employees"

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.
