Yes, indeed it will, since Japan's (and most other countries) pensionsystems are constructed to be financed by the young. You don't pay your own pension but someone else's grannie. So get your own retirement fund.
Demographics are interesting. One of the reasons that Africa is poor is that such a huge percetage of the population is so young and youngsters don't produce that much. The young are African so let in the young in your country or you will die poor (nice slogan for the social democratic party in the 2006 election, isn't it Anders?)
