The word nakōdo (仲人) means "matchmaker or go-between". In the past, when arranged marriages or o-miai were more common, the nakōdo would seek out suitable prospects for a man or woman and introduce them with photos and a resume.
Now, something I didn't until very recently know about this o-miai business is the money involved. A matchmaker could earn a million yen or more for a successful match, quite a bit of cash ($10K~). And he or she would be given gifts every summer and winter until his or her death. Not a bad gig.
Insurance salesladies often took on this service as a side business as they had a large number of contacts and were privy to all kinds of private information.
Even today, when more and more couples are marrying for "love", nakōdo are still invited to perform a ceremonial role at the wedding itself. If the groom is, for instance, a doctor, he might invite one of his professors or an important doctor from his hospital to do the duty. The nakōdo will receive from ¥500,000 to over ¥1,000,000 for this service, which usually amounts to sitting in front of everyone at the wedding, making a long and tedious speech and then getting drunk.
As of today, I hereby throw my hat into the nakōdo business for the low, low cost of ¥350,000 a pop. I'm sure I can scrounge up a mourning coat somewhere and, more importantly, I promise I will not to get too stinking drunk and embarrass everyone at the nuptials.
You know where you ca--HIC--can find me.
