A Canadian single father who filed a complaint against Mitsubishi UFJ Morgan Stanley Securities Co. — claiming he was harassed after he took a paternity leave — said Thursday that he hopes his case will highlight workplace struggles faced by fathers in Japan.

"I saw a lot of women in the company going through this and suffering like this, and I got to the point where I couldn't stay silent," Glen Wood, 47, told a news conference at the Foreign Correspondents' Club of Japan in Tokyo.

And the hurdle is higher for men, he says.
