A topical issue in Japan is the plight of foreign workers, more specifically, migrant workers, generally and more specifically in the wake of the GEC. A new documentary looks at their plight. Their site suggests the full video may be online at some point. Until then, I can't speak to the quality of the whole production. Worthwhile knowing it is doing the rounds though.
