In my experience... yes, yes, absolutely yes. It's really confusing to me, I guess, because of my background. I mean, guys in Japan can be REALLY emotional - more emotional than guys in my culture. Still, they don't express their emotions verbally like guys in my culture do. It's like they're not supposed to.
I also remember a book saying the difference between American and Japanese comics: an American comic is packed with words, while Japanese comics are packed with pictures expressing emotions.
So it's natural for them to be as emotional as women, but they can't talk about it. That's the sense I got, anyway.
