A group of dads and their small kids gathered around for a step-by-step demonstration of how to make perfect French toast. Then they got busy cracking eggs and beating them, cutting the bread into small squares that they dipped in the egg and then dropped into a hot skillet to watch sizzle as a buttery scent wafted through the room. Finally, they sliced up some banana and strawberry and topped the whole thing off with whipped cream. Voila!

"In 'Kramer versus Kramer,' (a film about a man who is suddenly thrust into single fatherhood) Dustin Hoffman can't make French toast," said Tomoyuki Katayama, the event's organizer. "But then he learns how and does it beautifully at the end."

That little anecdote sheds light on the events that led 41-year-old Katayama to the Gender Equality Center in Nishinomiya city in Hyogo Prefecture on a Saturday morning in mid-January. He was there to help local dads bond with their kids over French toast, to give a talk on the state of single fatherhood in Japan and offer his thoughts on the way forward, as he recently had in a bunch of other cities.
