Actually it's probably less than we think, since most people seem to think most of them are dating secretly. I'd suspect that more of them are in the "working hard to be an idol" school than we think. RKA is right in that who wants to hear about some chicks relationship woes? Who wants some jilted boyfriend turning up at a handshake event or theater causing embarrasment? Who wants to spend thousands of yen on some chick who's publicly dating some dirtbag? And I think in a lot of ways the RKJ protects the girls in prominent idol groups. If it wasn't there and girls did date freely then you can guarantee that lurid "sex life of idol" stories would be common in the tabloids and and dirt-blogs, nude and semi-nude "revenge porn"-style pics would be published and posted online (just look at the Tulisa from N'Dubz case or the SKE kks who had a bj pic show up) . The thing is most of the girls are in their teens or early 20's, they are in the public eye but (most of them) are not well paid....they aren't in a job where they can easily survive stories like that getting out. Anyway I don't want to derail the thread any more than that.
