Japanese bachelors are playing with dolls to help them find wives

Old-world customs are quickly falling out of favor in Japan.

Men and women no longer fall along typical gender lines of bread-winning and child-rearing. Instead, today's Japanese women are delaying marriage for their careers, while the country's bachelors are expected to lean into family life.

In 2010, the government launched the Ikumen Project, a campaign meant to teach single men the art of fatherhood and help them find wives. The name ikumen comes from a term coined by advertisers to describe men who take an active role in raising their children.

In a new workshop, put on by the Osaka-based company Ikumen University, men put on weight suits, change diapers on dolls, and learn what it takes to be a dad. Here's a look inside.
