I couldn't find the full article on-line, but doesn't this strike anyone as really odd? Not the women looking for better oppertunities thing (oh how they deserve it), but companies hiring Japanese workers to work in a foreign location at foreign wage levels? If you are going to pay Person A the same as Person B, why base your decision on which one has the same nationality as you? Don't tell me there aren't a bevy of Japanese speaking Koreans, Chinese, or other Asian workers who could fill the same job.
Other Asian countries not male dominated? Since when? Maybe less than Japan, I honestly don't know, but don't let The Man sell working abroad as gender equality heaven.
Oh, but I forgot, they want Japanese workers, who they will probably be more willing to promote even if they are women. Ah, now it all seem clear...
