Japanese weddings

My boss's daughter is getting married today and I'm sitting alone at the office, answering phone calls. Not that I mind - this wedding will probably a very boring affair.
The family that I live with is very old - my boss is the 13th head of it - so they are very traditional and that is why this was an arranged marriage. "Omiai kekkon" - arranged marriage - is still very common in Japan (especially in old, rich families); after all they can't give their child away to just every family. During and omiai the smallest details are taken into consideration - family's status, wealth, history, medical records, etc - there are even special archives that you can check before marrying someone. I don't know the exact data, but I've heard that about 20-30% of marriages are arranged and they are considered to be more stable and lasting than "renai kekkon" - marriage for love - because there are no strong feelings involved; the whole thing is more like a business deal.
I can believe that there are some people who are okay with that - they don't want to risk emotional pain, family's rejection or just seem to not care much about who are they marrying (I have a strong suspicion that that's the case in my boss's daughter's case; plus, she probably wants to get out of her mother's clutches. My boss is a very interesting woman, but she can also be the most overbearing person in the world...) - but for me it would be not acceptable. Who knows, maybe I'm just too emotional or I've seen one too many romantic movies.
The other thing is that the couple usually doesn't have mutual friends and they don't hang out with each other - the husband is supposed to go drinking with his collegues and the wife goes shopping with her gilrfriends. Basically, they just meet from time to time at home - they are more roommates than a couple in my opinion. But most of the Japanese girls I've talked to seem to be okay with that - they don't want their husband to meddle with their personal life. I've never broached the subject with a guy; I wonder what are their thought on the matter.
