I'm no linguistics expert but how men and women speak in Japan seems quite a bit different. It might be an over generalization but when men speak it seems faster and everything runs together more. When women speak it's usually a bit slower and the words are enunciated more clearly...easier for a Westerner just learning the language to understand. Admittedly, I've never been to Japan so that idea comes more from what I've seen in movies/TV/anime than anything else.
