I wrote a long response to this, but decided to simplify.
I think Japan's big problem is a matter of rapid cultural change since the end of World War II, gender roles have been moved around substantially. For girls to not be forced into arranged marriages and be able to say "no" is fairly new, and for guys in a culture that still has a big focus on "face" the abillity of a girl to say "no" and be cruel about it is unusually horrifying, more so than cultures where this has been the case for a much longer period of time, or where things had not been so rigid in the past.
I also think there is an issue with standards of beauty, I've read some stuff analyzing lolicon and the reasons for it, and the conflict between the Japanese tradition of child brides and attributing youth to beauty (which leads into things like the high pitched voices cultivated in public service) and recent enforced changes against having sex with children.
Basically in a culture where a generation or so ago, it was expected that someone was going to marry a 12 year old who might not have much choice in the matter, suddenly being in a generation that has to court girls on a much mor equal footing can probably be awkward with surprisingly little to have learned from. I mean if your parents were around when mine were in the 1960s or whatever, only a decade or two after WW II and did things "traditionally" how do people from a borderline arranged marraige reassure their kid about dating?
There is also apparently a trend towards having wives that are much younger than you are. This means some guy marrying late in life might expect to marry an 18 to 20 year old and of course with women having more empowerment and choice in the matter.. that might be tricky, especially if the guy doesn't have money.
Not to mention the tradition I've read about which is still apparently in force to an extent where the wife is expected to help take care of the husband's parents and such. Oftentimes leading to a wife having to virtually abandon their own family, which again is not exactly an appealing prospect that has girls jumping up and down with joy now that they have more of a choice in the matter.
That's my thoughts at any rate.
