There is no longer such a stigma about being single(20 years ago, when I first came to Japan, if you were near 30 and still single, people thought there was something wrong with you! :shock:
Arranged marriages("omiai" in Japanese) over here tend to have a longer success rate as the couples are marrying for reasons other than love. (Security, to have a partner, to raise a family, etc) Most young people nowadays hope for love marriages in the future.
I have also heard of "modern" arranged marriages where the man and woman are matched up (not as in a dating agency), they go out a few times (family backgrounds/checks are carried out to "ensure" compatibility) and then if the couple like each other, they marry. I have read a few articles where some have said that they like this because it takes some (a lot?!?) of the pressure out of dating/trying to meet someone for love.
