Every year, children in schools all across Japan take part in a sports day. It's one of the most important dates on the calendar, not just for the students, but for their parents too. This time on Japanology Plus, our theme is school sports days. Our main guest, sports writer Masayuki Tamaki, talks about their history, how they've changed, and their future. And in Plus One, Matt Alt follows a family as they prepare for, then attend, a primary school sports day.
