Few of the participants are talking about their favorite hobbies, movies or restaurants, or indeed, even about themselves. They are talking about their grown-up, still single children who they are hoping to match up and marry off. One woman, in her 60s, speaks proudly of her 34-year-old son, a public elementary school teacher. A man in his 80s talks affectionately about his career-minded son, 49, who works as a controller at an electric company. Each of the parents has forked out 14,000 yen ($96) to attend this event, hosted by the matchmaking agency Association of Parents of Marriage Proposal Information. And they are all hoping to meet someone just like them; a parent whose still single daughter or son might be the perfect match for their own lonesome child. It's not that Japan, a notoriously work-obsessed nation where time is at a premium, hasn't tried out the more direct approach to speed-dating, where the youngsters do it for themselves. It's more that leaving the young to it doesn't seem to be working.
